    # 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 endpoint in this API Reference.)*

    - The **Config API**, which you can use for configuration and management. *(All other endpoints in this API Reference.)*


    ## 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 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 one. 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

    ```
