Hey @milaapmp
So your best choice here would be to user our Server to Sever OAuth app
The only thing that changes is the token generation (the API calls will remain the same)
With the JWT app type you use your API key and Secret to create a JWT token.
With the Server to Server OAuth endpoint, you will use the credentials associated with your app (account ID, client ID and client Secret) to request an access_token to our OAuth endpoint
Here’s a helpful post on how to generate access tokens using Postman
