• I have created an integration flow with http sender which just outputs “This is a test message”.

• Select the Authorization as “Basic Auth” . Input “ClientID” value as username and “Client Secret” value as password.


• Now, send the message and you will get a response back with the access_token.

• Now, call the actual integration flow URL now by selecting the authorization as “Bearer” and input the value which you have got in the access_token field of the previous step.

• Hurray!! Its success and we have got the expected response back.


• The Postman test can also be done in another way. Call the Integration Flow endpoint directly by selecting the authorization as “Oauth 2.0”.


• Then, Configure the new token by selecting the Grant type as “Client Credentials” and fill in the appropriate filed with its respective data.

• Click “Get New Access Token” --> ”Proceed” --> “Use Token”. Now, send the request and you can see the same expected response.


• Also, you can see sync button and select the same to get the access token each time the request is being made.

• Hurray!! Its success again and we have got the expected response back.
