The EMMA API uses the OAuth2 authentication protocol. Authentication is done by obtaining a token with a user that has access to the apps we want to interact with via the API.
The base URL of the api is https://ws.emma.io.
Before connecting to the EMMA API we must know the API Key of our application.
See cobo to get the EMMA Key at https://docs.emma.io/en/configuracion#general-emma-key
To obtain the token we must first make a call to the /oauth2/login endpoint with the following parameters:
{
"username": "username",
"password": "password",
}
Example of a call using cURL
curl -X POST "https://ws.emma.io/oauth2/login" -H "Content-Type:application/json" -d "{\"username\": \"your-username\", \"password\": \"your-password\"}"
Sample response:
{

}
For authenticated API calls we must send the apiKey header with the content of our API Key and the Authorization header with the content of the token_type and access_token that we have obtained from the /oauth2/login call.
