For Simpplr B2B API
See the steps in Create a Client Application with Client credentials grant type. Please note only a user with Application manager role can do this.
Once you have the client credentials you can check and try out the B2B API as described below
1. Generate an access token
To try out a B2B API, you will have to generate an access token. To create the token, navigate to OAuth token endpoint API under B2B section, enter the client ID and secret and trigger the API.

2. Test if the token works hitting the test API
We will try to fetch the users in the system.
- Click
Authorization -> Test
in the left navigation panel under B2B section - Enter the access token in the credentials section. Note if you had logged in, this would have been pre-filled with access token for trying out the User API. Replace it with the token from the earlier step.
- Click
Try It

If this works, you can try the other B2B API of your interest.
