As part of the integration process, you need to set up an HTTPS webhook endpoint where CryptoProcessing can send callbacks. After you create the endpoint, register it in CryptoProcessing.
Keep a Master API key active to receive callbacks. CryptoProcessing does not send or queue callbacks while no Master key is active.

​
Set up callback URL

1

In your portal, go to Settings and switch to the Callbacks tab.

2

Click Set up URL.

3

Specify the URL of your webhook endpoint.

Your webhook URL must use HTTPS, use a domain name, and be considered safe by VirusTotal and similar scanners.
4

Enter your 2FA code and click Set up URL.

For additional security, you can whitelist the CryptoProcessing IP addresses used for callback delivery. Contact Support for the current list of IP addresses.

FAQ

​
Can I add more than one callback URL?

No. You can only add one callback URL per merchant account. Setting up a new URL replaces the existing one.
