Update Webhook
PATCH /webhooks/:webhookId
You can update the following fields: url, eventTypes, description, enabled. Fields you leave out stay as they are, and description: null removes the description. The secret stays the same and is not included in the response.
To stop webhook events for a while, set enabled to false:
{ "enabled": false }
The errors are the same as for Create Webhook, plus 404 with WEBHOOK_NOT_FOUND when the webhook doesn't exist, was deleted, or has the other mode (live or test) than your API key.
