# Error codes The Zoom API uses HTTP Status codes to reflect a successful or unsuccesful request. 2XX status codes represent a successful request, 4XX/5XX status codes represent an error took place. If you receive an error status code, check the body for an error code and message. ## Status codes | Status Code | Description | | ----------- | ------------------- | | `2XX` | Successful request. | ## Client error codes (4xx) | Status Code | Description | Most Likely Cause | | ----------- | ----------------- | --------------------------------------------------------------------------------------------------------------------------------------- | | `400` | Bad Request | Invalid/missing data. | | `401` | Unauthorized | Invalid/missing credentials. | | `403` | Forbidden | User does not have permission or has not authorized [shared access permissions](/docs/api/using-zoom-apis#shared-access-permissions). | | `404` | Not Found | The resource doesn't exist. For example, invalid or non-existent user ID. | | `409` | Conflict | The request conflicts with the current state of the resource. For example, creating a user with an email address that already exists. | | `429` | Too Many Requests | The request exceeded an [API rate limit](/docs/api/rate-limits/). Review your request frequency and implement retry logic with backoff. | ## Zoom-specific | Status Code | Description | Most Likely Cause | | ----------- | -------------------- | ----------------------------------------------------------------- | | `4700` | Invalid Access Token | The access token is invalid, expired, or missing required scopes. | ## Server error codes (5xx) 5xx errors indicate a server-side issue unrelated to your request. Implement retry logic with exponential backoff and jitter. If errors persist, check the [Zoom Status page](https://www.zoomstatus.com/) for ongoing incidents. | Status Code | Description | Most Likely Cause | | ----------- | --------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | `500` | Internal Server Error | An unexpected error occurred on Zoom's servers. Retry with exponential backoff; if the issue persists, contact [Zoom Support](/support/). | | `502` | Bad Gateway | Zoom's gateway received an invalid or no response from an upstream service. Retry after a short delay. | | `503` | Service Unavailable | Zoom's servers are temporarily unavailable, possibly due to scheduled maintenance or high load. Retry after a brief delay. Check the [Zoom Status page](https://www.zoomstatus.com/) for known incidents. | | `504` | Gateway Timeout | Zoom's gateway timed out waiting for an upstream service to respond. Retry the request. Consider using pagination or filters if your request involves large datasets. | ## Error response example ```json { "code": 300, "message": "Request Body should be a valid JSON object." } ``` ## Error response when sending invalid fields ```json { "code": 300, "message": "Validation Failed.", "errors": [ { "field": "user_info.email", "message": "Invalid field." }, { "field": "user_info.type", "message": "Invalid field." } ] } ```
