To use the sandbox environment, you must generate a token using your test credentials (clientId and clientSecret from the dashboard) and the sandbox base URL (https://sandbox.nomba.com). Using the wrong URL or credentials will cause authentication failures. See the Environment page for details.
Endpoint paths are the same as production — the sandbox is selected by the base URL and your test credentials, so you can point an existing integration at https://sandbox.nomba.com without changing your routes.

Before you start

  1. Generate a sandbox token — POST https://sandbox.nomba.com/v1/auth/token/issue with your test clientId and clientSecret
  2. Set a test webhook URL — on the dashboard under Developer → Webhook Setup, and subscribe to the events you care about. Several sandbox scenarios report their outcome only by webhook. See Webhooks.
