Ensure your Loon integration works correctly by simulating Account Updater responses in the Loon sandbox.

Step 1: Request Access to Loon

📘

Note

The Loon sandbox is not available for self-signup at this time.

If you’re interested in Loon, contact us to request a demo. The Pagos Accounts team will email you with an invitation to our Loon Sandbox environment. Follow the link in the invitation to confirm your email address, create a Sandbox password, and complete your account setup.

Step 2: Generate Your Loon Sandbox API Keys

To generate your API keys:

1. Log into your Sandbox.
2. Click Developers at the bottom of the left navigation.
3. Click Create API Key.
4. Save the Client Key and Private Key in your secrets for future reference.

🚧

Important

This is the only time you can view this Private Key!

These API Keys are universal across the sandbox and will be used for testing both Toucan and Loon.

Step 3: Test Loon

You're ready to begin testing the full capabilities of Loon. Follow the instructions in our Loon Overview guide to perform the following actions in the Sandbox using our Sandbox testing values:

1. Authenticate to confirm your access to the Loon service
2. Set up webhooks to receive notifications when important events occur
3. Register encryption keys with Loon
4. Prepare your data to be transferred securely to Loon
5. Submit Card Update Inquiries via the API (sending files via SFTP is not currently possible with the Loon Sandbox)
6. Check the status of your inquiry jobs
7. Receive updated card details
