Webhooks for Tracking Activity
Webhooks allow you to track contact activity in the eSputnik in real time and automatically send notifications about each event to a specified client URL
Webhooks are configured by adding an external URL to your account. After that, you will automatically receive data about contact actions across various media channels via POST requests.
The system sends requests to your server whenever one of the following events occurs:
- Delivered — the message was delivered to the contact.
- Undelivered — the message could not be delivered.
- Read — the contact opened the message.
- Unsubscribed — the contact unsubscribed from the campaign.
- Clicked — the contact clicked on a link in the message.
- Spam — the message was marked as spam.
Note
Before setting up webhooks, you need to configure an URL on your server where you want to receive messages — POST requests in JSON format — and process the data accordingly.
Creating Data Export
Open the Data export tab in your account settings, click the New data export button, and select Webhook.

Connection
Add a Webhook name and specify the Webhook URL you previously set up on your server.

Autentification (optional)
If authentication is enabled on your server, enter the login and password that your server requires to accept requests. Enable the Authentication toggle and fill in the corresponding fields.

Export Activity Statuses
By default, all activity statuses are selected for tracking. You can modify this list by deselecting the checkboxes following to the statuses you don't want to track.

After setting up the data export via webhook, click the Save button.

The webhook will be active, and data will be sent in real-time to the specified URL.

Settings Verification
The system will check the URL's availability using the GET request. If errors occur, your server may block our request for various reasons. You can determine the exact cause based on the server error code on your side.
If the check is successful, the setup is complete.
After that, perform any action in your eSputnik account — for example, send yourself an email. The POST request in JSON format with information about the latest activity will be sent to the specified URL.
For example, if a contact receives an email, opens it, and clicks a link, the system will sequentially send three requests with the statuses: DELIVERED
, READ
, and CLICKED
.
If the webhook URL does not return the HTTP 200 response code, the POST request attempt is repeated with incremented intervals (1 minute, 2 minutes, 4 minutes, 8 minutes, and up to 1 request per hour). The following requests are postponed until the first one is successfully delivered, and then delivered in their sequence.
Webhook Deactivation
To deactivate the webhook, click the three-dot icon, select Deactivate webhook, and confirm the action.

Deactivation suspends the sending of requests, but the webhook remains saved in the system and can be reactivated later.
Data Export Editing
To change the settings, click on the webhook name, edit the data, and save the settings.

Alternative Methods for Tracking Activity Statuses
For comparison/alternative, the API method Get contacts activity is used.
It works by sending GET requests from your side, where you can specify a time interval (up to 3 months) and parameters (such as email, status, etc.).
