Authentication via API (Classic)

To interact with MightyCall API, you must first authenticate your request by obtaining an authorization token. Authentication is performed by sending a POST request to:

https://api.mightycall.com/v4/auth/token

This endpoint returns a bearer token, which is required to access all other API methods. The token is valid for 24 hours, after which it must be refreshed or reissued.

There are 2 ways Classic customers can authenticate via API:

• By using their API key + User key, if they have a User key generated and toggled on in API integration;

• By using their API key + extension, if they don’t have a User key generated and toggled on in API integration.

So, for John here we will use the first method, and for Peter – the second one.

1. Create a new HTTPS request in your API client (we're using Postman here).

    

   

2. Select a method for your API request (we'll need POST for this case) and enter the endpoint: https://api.mightycall.com/v4/auth/token
   
   
3. In the Headers tab, add the following information:
   
   

   Key	Value
   x-api-key	The API key that from your account's API Integration section
   Content-Type	application/x-www-form-urlencoded

   
4. In the Body tab select x-www-form-urlencoded and enter the following:
   
   

   Key	Value
   grant_type	client_credentials
   client_id	The API key that from your account's API section
   client_secret	Your User key or extension

   John is using his User key as client_secret:
   
   
   Peter is using his extension as client_secret:
   
   
5. Click to Send the request. As a result, you should receive a 200 OK response containing your access_token (bearer token) valid for 24 hours, of which can be used for authorization in further API requests.
   
   
6. You can use refresh_token to include in the body of your new authentication API request: it will regenerate the bearer token and reset the 24 life cycle timer. In that case, you will need to change grant_type to refresh_token and remove other parameters from the Body tab:
