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 dashboard.
How to get sandbox keys
Log into your merchant dashboard at dashboard.watenga.africa. Go to Developer in the sidebar. Click New App and select 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.
