From the administration panel, select the Integration section and go to the "Tracking Systems" tab

Activate the integration below and enter the app_id, which you can find in edrone's settings, under Integrations.

Go to the Integration in edrone settings and find the "Syncing subscription status" section. Here you need to input the endpoint address, which contains the name of your domain and "/inne/edrone.php" postfix, for example:
https://examplestore.com/inne/edrone.php

Next, you need to choose a version, the current one is NATIVE_4 and which types of status you want to send to your platform.

The last step is to set the status to Enable and press 'Save'
