Telegram error 404: Not Found

The request path did not match /bot<token>/<method> in a way Telegram recognizes. HTTP 404 with description Not Found is returned when the method name does not exist (a typo such as sendMesage, or a method from a newer API version than the server supports) or when the bot prefix is missing or mangled so the path does not route to a bot at all. An empty or wildly malformed token can also land here rather than at 401.

It is easy to confuse this with a 404 from your own webhook endpoint, which appears in getWebhookInfo.last_error_message as Wrong response from the webhook: 404 Not Found. This entry is about the Bot API itself returning 404 to a request you made.

Method names are case-insensitive per the docs, so casing is not the issue; spelling and the path prefix are.

{"ok":false,"error_code":404,"description":"Not Found"}

Use a maintained client library so method names are checked by the compiler or at import time. Centralize the base URL and token in a single client instance with a startup getMe check. Keep local Bot API server versions in step with the features you use.

When the path is right but the token is bad, you get 401 Unauthorized instead; testing the token and path together with getMe via the token checker distinguishes the two in one step. A 404 in getWebhookInfo.last_error_message is your endpoint's 404, not Telegram's; that side is covered in the webhook debugging guide.
