Webhooks
Learn how to use webhooks to get alerts on subscriber and post events.
Checking for the API Key
We send a
POST request to the webhook endpoints you specify. To verify that the request came from Letterdrop, check for a field in the header of the request with key api-key and make sure it matches the value in your Settings.If the API Key is absent, you're getting hit up with requests from our evil twin from another dimension. Do not trust him under any circumstances!
