Sandbox

Test integrations without moving real money. Use base URL https://api.watenga.africa with sk_test_* and pk_test_* keys from a Sandbox app in the Developer Console.

How to get sandbox keys

Open the Developer Console → Apps & credentials. Click New App and select the Sandbox environment. Your sandbox Client ID and Secret Key are shown after creation.

Sandbox and Live are separate apps with separate keys. Never mix them.
