# webhook_endpoint_limit_reached

- HTTP status: 409
- Retry: No
- Execution: not started
- Admin needed: no

**Webhook endpoint limit reached.** Each workspace can have a limited number of webhook endpoints per mode (test and live counted separately).

## What it means

The API returns HTTP 409 with `error.code` set to `webhook_endpoint_limit_reached`. The default message is: "This workspace already has the maximum number of webhook endpoints for this mode."

## Common causes

- The limit in `details.limit` was reached.

## How to identify it

Check the response status (`409`) and `error.code` (`webhook_endpoint_limit_reached`). Branch on `error.code`, not on the message text: messages can be reworded, codes do not change within v1. Log `error.request_id` (also sent as the `X-Request-Id` header) so support can find the request.

## How to fix it

- Delete an endpoint you no longer use, or subscribe one endpoint to more event types.

## Retry guidance

Sending the request unchanged fails the same way. Fix the cause first (see How to fix it), then send it again.

## Did anything happen?

This request was refused before any call was placed and before anything was charged.

## Idempotency

Nothing was done and the refusal is not stored under the Idempotency-Key. Fix the cause, then send the same request (with the same key if you sent one).

## Who can fix it

The developer who sends the request can fix it; no administrator action is normally needed.

## When to contact support

If the error persists after the steps above, contact [support@relationsai.com](mailto:support@relationsai.com). See [Support](/resources/support) for what to include (the `request_id`, the time in UTC, the operation, and whether you used a test or live key) and what never to send (API keys, Authorization headers, webhook signing secrets, recording links, transcripts or customer data).
