# List event types

Source: https://docs.coderhelm.com/api/reference/webhook-endpoints/list-webhook-event-types

`GET /api/webhooks/event-types`

Every event type CoderHelm sends, with an example event. The `webhooks` section of this document has each one's schema.

## Authentication

A team API key: `Authorization: Bearer chk_...`. The key needs the `webhooks` scope. See [Authentication](https://docs.coderhelm.com/api/authentication).

## Responses

### 200

The catalog.

Headers: `RateLimit-Limit`, `RateLimit-Remaining`, `RateLimit-Reset`.

### 401

The key is missing, malformed, revoked or expired, or the person who made it left the team.

### 403

The key lacks the scope this endpoint needs (`missing_scope`).

### 429

Over the key's rate limit (`rate_limited`), or, for endpoints that start work, over the team's monthly token limit (`token_limit_reached`).

Headers: `RateLimit-Limit`, `RateLimit-Remaining`, `RateLimit-Reset`, `Retry-After`.

### 500

Something failed on CoderHelm's side. Safe to retry reads.
