How to enable webhooks for Email service

A webhook is a mechanism for receiving notifications about certain events. You can set up notifications about email deliverability and subscriber activity.

How to create a webhook

To create and send webhooks automatically, go to the Account Settings section in the API tab and click Create a webhook.

Select the event triggered by the webhook in the email service regarding sending an email:

• email marked as spam;
• email opened;
• link in the email clicked;
• new subscriber;
• subscriber unsubscribed;
• subscriber deleted from the list;
• delivered;
• campaign status changed,
• soft bounces,
• hard bounces.

Next, specify the URL, to which notifications will be sent.

For each event, you should create separate webhooks.

Send data format

When a webhook is triggered, SendPulse sends a POST request to the specified URL with the JSON data type.

Data is sent every minute or when the limit of 100 events is reached.

Data is sent in the following format:

[
  {
    "timestamp": "1496827422",
    "event": "event_name",
    "task_id": "3668141",
    "email": "john.doe@sendpulse.com"
