Looks like your WhatsApp Trigger node might need to be re-authorized.

Go to the node settings and click “Re-authorize” to refresh the connection with Meta. Let me know if this works!

Hello Achamm,

Thanks for responding. We tried that suggestion too, but it didn’t work.

We followed the steps in the 1 link below, and we were able to make the trigger work correctly.
