Step 1: Open our test Facebook Page:

Then click "Message" to start chat.

Step 2: From a real Facebook tester account (added in App Roles -> Tester), send this exact message:
Test from Meta review

Step 3: Our server receives the webhook at:
https://chatbot.hikmatech.com/public/webhook.php

https://chatbot.hikmatech.com/public/index.php

Step 5: Log in with temporary reviewer credentials:
Username/Email: [TEMP_USERNAME_OR_EMAIL]
Password: [TEMP_PASSWORD]

Step 6: Open the newest thread and confirm the incoming message "Test from Meta review" is visible.

Step 7: Send a reply from the inbox UI.

Step 8: Confirm the reply appears in the same Messenger conversation.
