WhatsApp Business Cloud Coexistence: “Resource not found” after Meta says “Account connected to Make”

[Ilie_Florentina]

What is your goal?

I want to connect my existing WhatsApp Business App number to Make using WhatsApp Business Cloud Coexistence, so I can use the Watch Events module and automate WhatsApp conversations.

What is the problem & what have you tried?

I am trying to connect an existing WhatsApp Business App number to Make using WhatsApp Business Cloud → Watch Events with Coexistence. Meta Embedded Signup completes successfully and shows “Account connected to Make”, “Phone number connected” and “Your account is active”. However, when Meta redirects back to Make, I get “Resource not found” and the connection is not saved.

I have tried creating the connection again and repeated the Embedded Signup process, selecting the existing WhatsApp Business account, existing phone number and Coexistence option. I also confirmed that two-step verification is OFF, the Phone Number ID exists, Make is listed as a partner in Meta, and Make has the required WhatsApp permissions.

I also checked Make → Credentials → Connections, and no connection was created. The result is the same after retrying. I do not want to deregister, replace or remove the existing production WhatsApp Business number.

Error messages or input/output bundles

Error message: “Resource not found”

The error appears after Meta Embedded Signup completes successfully and redirects back to Make. The connection is not created or saved, so there are no input/output bundles available.
