Webhooks

Webhooks allow you to subscribe to real-time notifications about various events that occur in MailerLite. For example, when a new subscriber is added to your account, HTTP POST callback is sent to your provided URL with a payload containing the new subscriber. It allows you to get the most recent updates without constantly polling the API. You can see your existing webhooks, create new, update and delete them.

Security

Webhook requests include Signature header, its value is HMAC (sha256) which is generated from payload JSON using webhook's secret. You can check its validity in order to be guaranteed that a request is sent from our side.

An example of a function which produces a signature in PHP:

public function generateSignature(string $jsonPayload, string $secret): string
{
    return hash_hmac('sha256', $jsonPayload, $secret);
