What a WhatsApp API error response looks like
When an API call or message send fails, Meta returns an error object rather than a successful response. Understanding its shape is the first step to diagnosing any issue quickly.
A few commonly seen error codes
These are illustrative examples only- not exhaustive. Always check Meta's official Cloud API error-code reference or contact Get Click Media support for the current definitive list.

Common WhatsApp API error
categories, grouped by cause
Most errors fall into one of these four buckets- knowing which one narrows down the fix fast.
Template & Policy Errors
Occur when a message template is unapproved, paused, or the content violates WhatsApp's messaging policy. Example: sending a template that Meta has since rejected or disabled.
Authentication & Token Errors
Error 190 is a common illustrative example- typically tied to an expired or invalid access token used to authenticate API calls.
Rate-Limit Errors
HTTP 429 responses signal you've exceeded your current messaging tier or API call rate limit and need to slow down or request higher limits.
Recipient / Number Errors
Errors like 133010 typically mean the destination number isn't registered on WhatsApp or is otherwise unreachable.
5 steps to diagnose a WhatsApp API error
Read the error code and message
Note the numeric code, title, and any error_data detail returned in the response.
Check template status
Confirm the template used is approved and not paused, disabled, or edited since approval.
Verify number registration
Confirm the recipient number is active on WhatsApp and correctly formatted with country code.
Check access token validity
Confirm your token hasn't expired and has the required permissions.
Escalate if unresolved
Contact your BSP or Get Click Media support with the error code, timestamp, and message ID.

When to escalate to your BSP
Not every error needs a support ticket- these are the signals worth raising with your BSP rather than troubleshooting alone.
Error persists after basic checks
You've verified template status, number registration, and token validity, but the error keeps recurring.
Account-level restriction suspected
You suspect a quality rating drop, messaging limit change, or platform-side restriction beyond your control.
Related webhook events look off
Status updates or delivery events stop matching what you expect- check your webhook setup alongside the error.

Questions about WhatsApp API error codes
Meta's error responses typically include a numeric error code, a short title, a human-readable message, and often an error_data field with additional detail about what specifically went wrong.
It generally indicates a re-engagement message was attempted outside the 24-hour customer service window, meaning a template message is required instead of a free-form reply. Always confirm against Meta's current official error reference, as definitions can be updated.
It's commonly associated with an expired or invalid access token- the fix is usually to refresh or regenerate the token used for API authentication.
HTTP 429 typically signals rate limiting- your app is sending requests faster than your current messaging tier or API rate limit allows. Slowing down request volume or requesting a tier increase usually resolves it.
It's typically related to the recipient's phone number not being registered on WhatsApp, so the message cannot be delivered to that number.
No- this page lists a few well-known, illustrative examples to explain common error categories. Meta updates and expands its error codes over time, so always check Meta's official Cloud API error-code reference or contact Get Click Media support for the current definitive list.
Escalate when an error persists after checking the basics- template status, number registration, and token validity- or when you suspect an account-level restriction, quality rating drop, or platform-side issue that you can't resolve from your side alone.
