WhatsApp error 135000
Error 135000: Unknown error in the request
Error 135000 means Meta could not send the message because of a problem with the request’s parameters that it did not name. Check the request against Meta’s endpoint reference; if it still fails, contact Meta support.
- Meta’s description
- “Message failed to send because of an unknown error with your request parameters.” Meta’s error codes, 5 October 2026
- Charged by Meta?
- No. Meta charges only for delivered messages, and this one was not delivered.
Common causes
- A request that does not match what the endpoint expects, in a way Meta does not identify.
How to fix it
- Check the request’s syntax and fields against Meta’s endpoint reference.
- If the request looks right and keeps failing, contact Meta support with the details.
What Fliok does about it
- Fliok does not handle 135000 specially: a send that fails with it may be retried a few times before it is marked failed.
Meta sets and changes these codes. If anything here disagrees with Meta’s current reference, Meta is right.
Both are unknown errors. 135000 points at your request’s parameters; 131000 does not say where the problem is.
