How to add your callback URL in the Portal
In your Portal navigate to eSIM Go Settings > API Details > Choose v3 from the dropdown.
Once you have added your callback URL click Save Changes.
Notifications to Expect
Notifications to expect are 1%, 50%, 80% and 100% usage notifications. All the notifications are displayed in this section of our developer documentation https://docs.esim-go.com/api/notifications/.
Troubleshooting your Callback URL
1 Checking the History tab in the Portal
If you find that you do not receive usage notifications you can troubleshoot first by checking the History tab in the Portal for the specific ICCID.
The History tab is available for every ICCID from the SIM Management section of the Portal.
If the notifications are present in the History tab in the Portal and you have still not received the notifications then you should check the configuration of your callback URL.
2 Using a third party website to test
This third party website is also a useful resource for testing webhooks by copying and pasting your callback URL:
