How to Fix the Generic User Error (135000) in WhatsApp Cloud API

Recently, we’ve encountered the frustrating “generic user error” (Error code: 135000) in the WhatsApp Cloud API, affecting several users. Many reported that their dynamic templates, which previously worked fine, suddenly stopped functioning.

Investigating the Issue

After verifying all API calls related to the templates, we found no mistakes on our end. Yet, the error persisted. Searching through the Meta Developer Forum, we discovered that while no official solution exists, a common workaround has helped many: deleting all templates and recreating them. (Source)

We tested this solution for multiple clients. Deleting and recreating the templates temporarily resolved the issue. To further ensure stability, we also removed and re-added the associated phone number, which ultimately fixed the problem for several users.
