Step 1: Setup your callback URL
You can use Flock's webhooks to send and receive messages from external services using JSON packets. An outgoing webhook sends messages from a Flock channel to an external service.
Before you create an outgoing webhook, you'll need to set up a Callback URL - an HTTP/HTTPS endpoint on your server that accepts JSON payloads. E.g. https://api.yourservice.com/callback
The messages are posted to your endpoint with the HTTP headers Content-Type: application/json;and Accept-Encoding: gzip, deflate. The JSON payload is in the body. If you need help setting up your callback URL, contact developer support.
