Postman collection

Explore every endpoint without writing code. The collection is generated from the same OpenAPI description as the API reference.

Download Postman collection Download openapi.json

Import and configure

In Postman, select Import and choose the downloaded collection file.
Open the collection’s Variables. baseUrl is set to the sandbox, https://api.sandbox.credchek.com.
Set apiKey to a sandbox key (cc_test_…). Use the Current value column so the key stays on your computer and isn’t synced.
Send a request, such as List products.

Use sandbox keys in Postman

Avoid putting production keys in shared workspaces. If you must test against production, create a short-lived, read-only key and revoke it when you’re done.
