> Set up OAuth2.0 with Client Credentials grant type in Postman for authenticating your service via Visma Connect.


In Postman, you can set the authorization method and details either per request or collection. To authenticate your service, perform the following setup:

1. Choose the **OAuth2.0** authorization type.

2. Select the **Client credentials** grant type.

3. Use the following access token URL: <https://connect.visma.com/connect/token>.

4. Fill in the client ID and the client secret.

5. Enter the scope `business-graphql-service-api:access-group-based`.

6. Select **Send as Basic Auth header** option for *Client Authentication*.

These settings are shown in the following image:
