Am trying to Integrate Salesforce Marketing cloud with Facebook Messenger with REST API as provided by the Salesforce help doc /ott/v1/send.
Am getting proper response from the Postman but not getting any messages in messenger:
Step 1: Register a Facebook Page via API
Step 2: Send message via /ott/v1/send
Am getting proper response back. But couldn't able to see any message in messenger.
Any help will be much appreciated.
