IP addresses

For your integration to work properly, you must ensure it can reach the IP addresses of Checkout.com's API. If your integration receives webhook notifications from us, make sure it also allows requests from Checkout.coms webhook servers.

You can retrieve the lists and update your allowlists programmatically.

Retrieve IP address lists

You can retrieve the IP address lists in machine-readable format from the following endpoints.

Production environment:

• https://checkout.com/docs/public/files/ip-lists/api-live.txt
• https://checkout.com/docs/public/files/ip-lists/webhooks-live.txt

Sandbox environment:

• https://checkout.com/docs/public/files/ip-lists/api-sandbox.txt
• https://checkout.com/docs/public/files/ip-lists/webhooks-sandbox.txt

Each file contains a list of IP addresses and CIDR blocks, with one address or block displayed per line.

Send requests to Checkout.com's API

Your integration will send requests to specific IP addresses, depending on whether you're in a live or sandbox environment.

Receive webhook notifications

If your integration is configured to receive webhook notifications, they will be sent from specific IP addresses, depending on whether you're in a live or sandbox environment.
