Respond to Activation
How to respond to the challenge required for your webhook-endpoint activation.
GET
Once your webhook-endpoint is declared in your Lucca account, our servers will send a GET request to your endpoint with a challenge string in query parameters. You must respond with the challenge value in the response body.
Some domains are whitelisted and won’t need to pass a confirmation challenge
(e.g. Zapier)
Path Parameters
Name of the webhook-endpoint on your server.
Maximum length:
500
Query Parameters
The challenge value you must return
Response
200 - text/plain
OK
When responding to the activation challenge workflow, return the challenge value as a simple string. When receiving a regular event, simply return an empty "200 OK". Refer to the documentation for all status codes and their meaning.
