Test Environments

Sandbox

Clearpay provides a sandbox environment for development and testing. Your Clearpay account manager will provide you with sandbox credentials.

Accounts created within a Clearpay sandbox only exist within the sandbox. When you make a transaction in the sandbox, no money actually moves.

API calls in the sandbox use the base URL https://api.sandbox.clearpay.co.uk.

Sandbox Business Hub

Contact your Clearpay account manager or delivery manager to request access to the sandbox Business Hub. The sandbox Business Hub provides the same functionality as the production Business Hub.

You can log into the sandbox Business Hub at https://portal.sandbox.clearpay.co.uk/

You can view all sandbox orders and settlement files, but no settlements are made to your bank account.

Test customer accounts

You can create test customer accounts in the sandbox environment within your test checkout flow. Each customer account requires a unique email address and phone number.

Note: No SMS messages are sent in the sandbox. Use 111111 as the verification code.

Test credit cards

The sandbox capture response (approved/declined) is determined by the CVV value. Use 000 for approval and 051 for decline.

You can use any dummy Visa or Mastercard number and future expiry date, as long as it passes a mod 10 check and hasn’t already been used by a different sandbox customer account. You can also use these dummy cards:

  2. Fork the collection.
  3. Choose a label, workspace, and environment for your fork.
  4. Regularly pull the latest changes to update your forked collection.
