Generate OAUTH Token

To test any REST services you provide via Apex, an OAUTH token will be required. This makes debugging simpler and faster.

See https://developer.salesforce.com/docs/atlas.en-us.api_rest.meta/api_rest/intro_understanding_username_password_oauth_flow.htm for a reference.

The following information is needed from the Connected App Configuration:

  • client_id
  • client_secret

The OAUTH Token is generated using CURL.

CURL - Generate OAUTH Token
curl -d "grant_type=password&client_id=<client_id>&client_secret=<client_secret>&username=<salesforce_user_name>&password=<salesforce_password><security_token>" -X POST https://login.salesforce.com/services/oauth2/token

NOTE: there is no space between <salesforce_password> and <security_token>

For the endpoints, use the following for the live system:

https://login.salesforce.com/services/oauth2/token

And the following for the test / sandbox system:

https://test.salesforce.com/services/oauth2/token

The following shows a sample response received from the SalesForce system:

 The portion in "access_token" is required for testing the APIs using CURL.
