# Introduction
The m3ter platform supports two HTTP-based REST APIs returning JSON encoded
responses:
- The **Ingest API**, which you can use for submitting raw data measurements.
_(See the
[Submit Measurements](https://www.m3ter.com/docs/api#tag/Measurements/operation/SubmitMeasurements)
endpoint in these API Reference Docs.)_
- The **Config API**, which you can use for configuration and management. _(All
other endpoints in these API Reference Docs.)_
## Authentication and Authorization
Our APIs use an industry-standard authorization protocol known as the OAuth 2.0
specification.
OAuth2 supports several grant types, each designed for a specific use case.
m3ter uses the following two grant types:
- **Authorization Code**: Used for human login access via the m3ter Console.
- **Client Credentials**: Used for machine-to-machine communication and API
access.
Complete the following flow for API access:
1. **Create a Service User and add Permissions**: Log in to the m3ter Console,
go to **Settings**, **Access** then **Service Users** tab, and create a
Service User. To enable API calls, grant the user **Administrator**
permissions.
2. **Generate Access Keys**: In the Console, open the _Overview_ page for the
Service User by clicking on the name. Generate an **Access Key id** and **Api
Secret**. Make sure you copy the **Api Secret** because it is only visible at
the time of creation.
See
[Service Authentication](https://www.m3ter.com/docs/guides/authenticating-with-the-platform/service-authentication)
for detailed instructions and an example.
3. **Obtain a Bearer Token using Basic Auth**: We implement the OAuth 2.0 Client
Credentials Grant authentication flow for Service User Authentication. Submit
a request to the m3ter OAuth Client Credentials authentication flow, using
your concatenated **Access Key id** and **Api Secret** to obtain a Bearer
Token for your Service User. _See examples below._
4. **Bearer Token Usage**: Use the HTTP 'Authorization' header with the bearer
token to authorise all subsequent API requests.
> Warning: The Bearer Token is valid for 18,000 seconds or 5 hours. When the
> token has expired, you must obtain a new bearer token.
Below are two examples for obtaining a Bearer Token using Basic Auth: the first
in cURL and the second as a Python script.
### cURL Example
1. Open your terminal or command prompt.
2. Use the following `cURL` command to obtain a Bearer Token:
```bash
curl -X POST https://api.m3ter.com/oauth/token \
-H 'Content-Type: application/x-www-form-urlencoded' \
-u your_access_key_id:your_api_secret \
-d 'grant_type=client_credentials'
```
Replace `your_access_key_id` and `your_api_secret` with your actual **Access Key
id** and **Api Secret**.
3. Run the command, and if successful, it will return a JSON response
containing the Bearer Token. The response will look like this:
```json
{
"access_token": "your_bearer_token",
"token_type": "Bearer",
"expires_in": 18000
}
```
You can then use the Bearer Token _(the value of `"access_token"`)_ for
subsequent API calls to m3ter.
### Python Example
1. Install the `requests` library if you haven't already:
```bash
pip install requests
```
2. Use the following Python script to obtain a Bearer Token:
```python
import requests
import base64
# Replace these with your Access Key id and Api Secret
access_key_id = 'your_access_key_id'
api_secret = 'your_api_secret'
# Encode the Access Key id and Api Secret in base64 format
credentials = base64.b64encode(f'{access_key_id}:{api_secret}'.encode('utf-8')).decode('utf-8')
# Set the m3ter token endpoint URL
token_url = 'https://api.m3ter.com/oauth/token'
# Set the headers for the request
headers = {
'Authorization': f'Basic {credentials}',
'Content-Type': 'application/x-www-form-urlencoded'
}
# Set the payload for the request
payload = {
'grant_type': 'client_credentials'
}
# Send the request to obtain the Bearer Token
response = requests.post(token_url, headers=headers, data=payload)
# Check if the request was successful
if response.status_code == 200:
# Extract the Bearer Token from the response
bearer_token = response.json()['access_token']
print(f'Bearer Token: {bearer_token}')
else:
print(f'Error: {response.status_code} - {response.text}')
```
Replace `your_access_key_id` and `your_api_secret` with your actual **Access Key
id** and **Api Secret**.
3. Run the script, and if successful, it will print the Bearer Token. You can
then use this Bearer Token for subsequent API calls to m3ter.
## Submitting Personally Identifiable Information (PII)
**IMPORTANT!** Under the
[Data Processing Agreement](https://www.m3ter.com/docs/legal/dpa), the only
fields permissible for use to submit any of your end-customer PII data in m3ter
are the `name`, `address`, and `emailAddress` fields on the **Account** entity -
see the details for
[Create Account](https://www.m3ter.com/docs/api#operation/PostAccount). See also
section 4.2 of the
[Terms of Service](https://www.m3ter.com/docs/legal/terms-of-service).
## Error Codes
The APIs return standard HTTP response codes to indicate request success or
failure.
- `200` code indicates success.
- `4xx` codes are failures due to problems with the request _(client side
errors)_.
- `5xx` codes indicate valid API requests and the failure is on the server side.
See
[HTTP Error Codes](https://www.m3ter.com/docs/guides/m3ter-apis/http-error-codes)
for examples and more information.
## Rate and Payload Limits
### Config API Request Rate Limits
- **Source IP Address.** Individual host machines can send up to 20,000 requests
over a rolling 5-minute period. _(An average of 66 requests per second)._
- **m3ter Organization** Each m3ter Organization can send a maximum of 50
requests per second from any number of source IP addresses.
If you exceed either of these rate limits, requests are throttled and an HTTP
429 _(Too Many Requests)_ error response is returned:
- **Source IP address rate limit** - 429 is returned until the total number of
requests in the rolling 5-minute period drops below 20,000.
- **m3ter Organization rate limit** - 429 is returned for the remainder of the
second in which throttling has occurred.
See
[Config API Limits](https://www.m3ter.com/docs/guides/m3ter-apis/config-api-limits)
for more information.
### Data Explorer API Request Rate Limits
As part of the Config API, requests made to the Data Explorer are subject to
tighter request rate limits:
- **Generally** 1 request per second.
- **Burst** 10 requests per second.
If you exceed either of these rate limits, requests are throttled and an HTTP
429 (Too Many Requests) error response is returned.
**Note: Burst limit for Data Explorer requests?** We allow short bursts of
higher TPS to allow us to accommodate occasional spikes. For example, if the
sustained rate is 50 TPS, we might set a bucket capacity (N) of 150. This means
that you can do up to 150 TPS for 1s (and empty the bucket), but in the next
second you'll only be able to do 50 TPS because that is all that has been
refilled. If requests drop below 50 TPS for a period of time, the bucket will
refill back up to full capacity allowing another spike. This is usually referred
to as "burst capacity".
### Ingest API Request Rate and Payload Limits
#### Request Rate Limits
- **Source IP Address.** Individual host machines can send up to 5,000 requests
over a rolling 5-minute period. _(An average of 16 requests per second)_.
- **m3ter Organization.** Each m3ter Organization can send a maximum of 50
requests per second from any number of source IP addresses.
If you exceed either of these rate limits, requests are throttled and an HTTP
429 _(Too Many Requests)_ error response is returned:
- **Source IP address rate limit** - 429 is returned until the total number of
requests in the rolling 5-minute period drops below 5,000.
- **m3ter Organization rate limit** - 429 is returned for the remainder of the
second in which throttling has occurred.
#### Payload Limit
For the Ingest API, the maximum request payload size allowed is 512KB. If you
exceed this request payload limit, then you'll receive a 403 (Forbidden) error
response.
See
[Ingest API Limits](https://www.m3ter.com/docs/guides/m3ter-apis/ingest-api-limits)
for more information.
## Pagination
**List Endpoints** API endpoints that have a List resources request support
cursor-based pagination - for example, the `List Accounts` request. These List
calls support pagination by taking the two parameters `pageSize` and
`nextToken`.
The response of a List API call is a single page list. If the `nextToken`
parameter is not supplied, the first page returned contains the newest objects
chronologically. Specify a `nextToken` to retrieve the page of older objects
that occur immediately after the last object on the previous page.
Use `pageSize` to limit the list results per page, typically this allows up to a
maximum of 100 or 200 per page.
**Search Endpoints** API endpoints that have a Search resources request support
cursor-based pagination - for example, the `Search Accounts` request. These
Search calls support pagination by taking the two parameters `pageSize` and
`fromDocument`.
The response of a Search API call is a single page list. If the `fromDocument`
parameter is not supplied, the first page returned contains the newest objects
chronologically. Specify a `fromDocument` to retrieve the page of older objects
that occur immediately after the last object on the previous page.
Use `pageSize` to limit the list results per page, typically this allows up to a
maximum of 100 or 200 per page. Default is 10.

---
API Quick Start This API Quick Start section provides an entry point to using
the m3ter APIs. The example given takes you through the steps of first
authenticating with the m3ter platform then going on to retrieve a list of
Accounts for your Organization. Code examples are provided in Python,
JavaScript, C++, and command line HTTP via `cURL`.
See also
[Getting Started with API Calls](https://www.m3ter.com/docs/guides/m3ter-apis/getting-started-with-api-calls)
for more on using our API with examples.
## Step 1: Create a Service User and add Permissions
Log in to the m3ter Console, go to **Settings**, **Access** then **Service
Users** tab, and create a Service User. To enable API calls, grant the user
**Administrator** permissions.
## Step 2: Generate Access Keys
In the Console, open the **Service Users Details** page for the Service User by
clicking on the Service User **NAME**. Generate an **Access Key id** and **Api
Secret**. Make sure to copy the **Api Secret** as it is only visible at the time
of creation.
For further guidance on these two steps, see
[Creating and Configuring Service Users](https://www.m3ter.com/docs/guides/organization-and-access-management/managing-users/creating-and-configuring-service-users)
in our main user Documentation.
## Step 3: Install Dependencies (if applicable)
### Python
Install the `requests` library:
```bash
pip install requests
```
### JavaScript
Install the `axios` library:
```bash
npm install axios
```
### C++
Install the `libcurl` and `jsoncpp` libraries.
For Windows based systems with `vcpkg` package manager installed:
```bash
vcpkg install curl[openssl] jsoncpp
```
For Debian based Linux operating systems:
```bash
sudo apt-get install libcurl4-openssl-dev libjsoncpp-dev
```
## Step 4: Obtain a Bearer Token using Basic Auth
Submit a request to the m3ter OAuth Client Credentials authentication flow,
using your concatenated **Access Key id** and **Api Secret** to obtain a Bearer
Token for your Service User.
### cURL
```bash
curl -X POST https://api.m3ter.com/oauth/token \
-H 'Content-Type: application/x-www-form-urlencoded' \
-u your_access_key_id:your_api_secret \
-d 'grant_type=client_credentials'
```
Replace `your_access_key_id` and `your_api_secret` with your actual **Access Key
id** and **Api Secret**. Run the command, and if successful, it will return a
JSON response containing the Bearer Token.
### Python
```python
import requests
import base64
# Replace these with your Access Key id and Api Secret
access_key_id = 'your_access_key_id'
api_secret = 'your_api_secret'
# Encode the Access Key id and Api Secret in base64 format
credentials = base64.b64encode(f'{access_key_id}:{api_secret}'.encode('utf-8')).decode('utf-8')
# Set the m3ter token endpoint URL
token_url = 'https://api.m3ter.com/oauth/token'
# Set the headers for the request
headers = {
'Authorization': f'Basic {credentials}',
'Content-Type': 'application/x-www-form-urlencoded'
}
# Set the payload for the request
payload = {
'grant_type': 'client_credentials'
}
# Send the request to obtain the Bearer Token
response = requests.post(token_url, headers=headers, data=payload)
# Check if the request was successful
if response.status_code == 200:
# Extract the Bearer Token from the response
bearer_token = response.json()['access_token']
print(f'Bearer Token: {bearer_token}')
else:
print(f'Error: {response.status_code} - {response.text}')
```
Replace `your_access_key_id` and `your_api_secret` with your actual **Access Key
id** and **Api Secret**. Run the script, and if successful, it will print the
Bearer Token.
### JavaScript
```javascript
const axios = require("axios");
const btoa = require("btoa");
const accessKeyId = "your_access_key_id";
const apiSecret = "your_api_secret";
const basicAuth = btoa(`${accessKeyId}:${apiSecret}`);
const url = "https://api.m3ter.com/oauth/token";
const options = {
method: "POST",
url: url,
headers: {
Authorization: `Basic ${basicAuth}`,
"Content-Type": "application/json",
},
data: {
grant_type: "client_credentials",
},
};
axios(options)
.then((response) => console.log("Access Token:", response.data.access_token))
.catch((error) => console.error("Error:", error));
```
Replace `your_access_key_id` and `your_api_secret` with your actual **Access Key
id** and **Api Secret**. Run the script, and if successful, it will print the
Bearer Token.
### C++
```C++
#include <iostream>
#include <string>
#include <curl/curl.h>
#include <json/json.h>
#include <sstream>
#include <cstdlib>
#include <base64.h>
size_t write_callback(void *contents, size_t size, size_t nmemb, void *userp) {
((std::string *)userp)->append((char *)contents, size * nmemb);
return size * nmemb;
}
int main() {
// Replace these with your Access Key id and Api Secret
std::string access_key_id = "your_access_key_id";
std::string api_secret = "your_api_secret";
// Encode the Access Key id and Api Secret in base64 format
std::string credentials = base64_encode(reinterpret_cast<const unsigned char*>(access_key_id.append(":").append(api_secret).c_str()), access_key_id.length());
// Set the m3ter token endpoint URL
std::string token_url = "https://api.m3ter.com/oauth/token";
// Initialize libcurl
curl_global_init(CURL_GLOBAL_DEFAULT);
CURL *curl = curl_easy_init();
if (curl) {
// Set the headers for the request
struct curl_slist *headers = nullptr;
headers = curl_slist_append(headers, "Content-Type: application/x-www-form-urlencoded");
std::string auth_header = "Authorization: Basic " + credentials;
headers = curl_slist_append(headers, auth_header.c_str());
// Set the payload for the request
std::string payload = "grant_type=client_credentials";
// Prepare the request
curl_easy_setopt(curl, CURLOPT_URL, token_url.c_str());
curl_easy_setopt(curl, CURLOPT_HTTPHEADER, headers);
curl_easy_setopt(curl, CURLOPT_POSTFIELDS, payload.c_str());
curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, write_callback);
// Send the request and store the response
std::string response;
curl_easy_setopt(curl, CURLOPT_WRITEDATA, &response);
CURLcode res = curl_easy_perform(curl);
long response_code;
curl_easy_getinfo(curl, CURLINFO_RESPONSE_CODE, &response_code);
// Check if the request was successful
if (res != CURLE_OK || response_code != 200) {
std::cerr << "Error: " << response_code << " - " << curl_easy_strerror(res) << std::endl;
} else {
// Parse the JSON response
Json::Value json;
std::istringstream(response) >> json;
std::string bearer_token = json["access_token"].asString();
std::cout << "Bearer Token: " << bearer_token << std::endl;
}
// Cleanup
curl_easy_cleanup(curl);
curl_slist_free_all(headers);
}
curl_global_cleanup();
return 0;
}
```
Replace `your_access_key_id` and `your_api_secret` with your actual **Access Key
id** and **Api Secret**. Run the program, and if successful, it will print the
Bearer Token.
## Step 5: Retrieve Organization ID
Copy your Organization ID from the m3ter Console by going to **Settings**,
**Organization**, then the **Configuration** tab. The Organization ID is
displayed on the _Organization Details_ card and you can **Copy** it directly to
your clipboard.
## Step 6: Retrieve Accounts List
Make a call to the
[List Accounts](https://www.m3ter.com/docs/api#tag/Account/operation/ListAccounts)
API endpoint using the Organization ID copied in the previous step. Use the
Bearer Token to authorize API calls in the HTTP 'Authorization' header.
### cURL
```bash
curl -X GET "https://api.m3ter.com/organizations/{orgId}/accounts?pageSize={pageSize}&nextToken={nextToken}" \
-H "Authorization: Bearer {access_token}"
```
Replace `{orgId}`, `{pageSize}`, `{nextToken}`, and `{access_token}` with your
Organization ID, desired page size, next token _(if needed)_, and Bearer Token
respectively.
### Python
```python
import requests
org_id = 'your_org_id'
page_size = 'your_page_size'
next_token = 'your_next_token' # Optional, use if needed
access_token = 'your_bearer_token'
url = f'https://api.m3ter.com/organizations/{org_id}/accounts?pageSize={page_size}&nextToken={next_token}'
headers = {
'Authorization': f'Bearer {access_token}'
}
response = requests.get(url, headers=headers)
if response.status_code == 200:
accounts = response.json()
print(accounts)
else:
print(f"Error: {response.status_code}")
```
Replace `{orgId}`, `{pageSize}`, `{nextToken}`, and `{access_token}` with your
Organization ID, desired page size, next token _(if needed)_, and Bearer Token
respectively.
### JavaScript
```javascript

console.log(accounts);
} else {
console.log(`Error: ${response.status}`);
}
})
.catch((error) => {
console.error(`Error: ${error.response.status}`);

# Integrations Webhook API Example
A major benefit of using m3ter is that it seamlessly integrates with your
current technology stack. You can create webhook destinations to link you
integrations using the API, or via the Console:
- This section provides a worked example showing you how to set up a Webhook via
the API.
- See
[Creating and Managing Destinations](https://www.m3ter.com/docs/guides/integrations/setting-up-native-integrations/creating-and-managing-destinations)
in the m3ter documentation for instructions on using the Console.
## Step 1: Create a Service User and Generate Access Keys
1. **Create a Service User**: Log in to the m3ter Console, go to **Settings**,
**Access** then **Service Users** tab, and create a Service User. To enable
API calls, grant the user **Administrator** permissions.
2. **Generate Access Keys**: In the Console, open the **Service User Details**
page for the Service User by clicking on the **NAME** hotlink text. Select
**Generate Access Key** to generate an **Access Key id** and **Api Secret**.
Make sure you copy the **Api Secret** because it is only visible at the time
of creation.
For further guidance on completing **Step 1**, see
[Creating and Configuring Service Users](https://www.m3ter.com/docs/guides/organization-and-access-management/managing-users/creating-and-configuring-service-users)
in our main user Documentation.
## Step 2: Obtain a Bearer Token using Basic Auth
We implement the OAuth 2.0 Client Credentials Grant authentication flow for
Service User Authentication. Submit a request to the m3ter OAuth Client
Credentials authentication flow, using your concatenated **Access Key id** and
**Api Secret** to obtain a Bearer Token for your Service User. Here's an example
in Python code:
```python
import requests
import base64
# Replace these with your Access Key id and Api Secret
access_key_id = 'your_access_key_id'
api_secret = 'your_api_secret'
# Encode the Access Key id and Api Secret in base64 format
credentials = base64.b64encode(f'{access_key_id}:{api_secret}'.encode('utf-8')).decode('utf-8')
# Set the m3ter token endpoint URL
token_url = 'https://api.m3ter.com/oauth/token'
# Set the headers for the request
headers = {
'Authorization': f'Basic {credentials}',
'Content-Type': 'application/x-www-form-urlencoded'
}
# Set the payload for the request
payload = {
'grant_type': 'client_credentials'
}
# Send the request to obtain the Bearer Token
response = requests.post(token_url, headers=headers, data=payload)
# Check if the request was successful
if response.status_code == 200:
# Extract the Bearer Token from the response
bearer_token = response.json()['access_token']
print(f'Bearer Token: {bearer_token}')
else:
print(f'Error: {response.status_code} - {response.text}')
```
Replace `your_access_key_id` and `your_api_secret` with your actual **Access Key
id** and **Api Secret**. Run the script, and if successful, it will print the
Bearer Token.
## Step 3: Create a Webhook (Destination)
After obtaining the Bearer Token, you can use it to authorize your API calls.
Here's a Python example of creating a webhook:
```python
import requests
import json
# API endpoint
url = "https://api.m3ter.com/organizations/{orgId}/integrationdestinations/webhooks" # replace {orgId} with your organization's UUID
# Headers
headers = {
"Content-Type": "application/json",
"Authorization": f"Bearer {bearer_token}" # replace with your actual Bearer Token
}
# Request body
payload = {
"url": "https://your-webhook-listener.com", # replace with your actual webhook listener URL
"credentials": {
"type": "M3TER_SIGNED_REQUEST",
"apiKey": access_key_id, # replace with your actual API key
"secret": api_secret # replace with your actual secret
}
}
# Make the POST request
response = requests.post(url, headers=headers, data=json.dumps(payload))
# Print the response
print(response.json())
```
## Step 4: Validate Incoming Requests
Once your webhook is set up, you'll want to validate incoming requests to ensure
they're coming from m3ter. All requests we make to your webhook are signed by
us. When you receive a request on your configured endpoint, validate the
`X-m3ter-signature` header by preparing a payload string that you sign with your
API secret.
You must concatenate the following data using a pipe '|' separator to compute
the payload:
- url
- query string - Currently, there's no support for passing in query parameters.
For now, you can hard code to this string: '{}'
- API Key - provided in the `X-m3ter-apikey` header.
- timestamp - provided in the `X-m3ter-timestamp` header.
- body - the request body.
You can now set up and validate webhooks using the m3ter Console and API. Always
refer to the latest [m3ter documentation](https://www.m3ter.com/docs) for
accurate and up to date information.
