Today
- Set or clear
webhookUrlfrom the dashboard (or apps API). - Top-up completion is also reflected when the React Native SDK finishes the sheet and your app refreshes balance via
getBalance. - Provider webhooks (for example PawaPay → Jaza) are handled inside Jaza — you do not implement aggregator webhooks.
Guidance
Prefer refreshing balance and UX from the mobile SDK callbacks (onTopUpComplete) plus your BFF. Treat outbound merchant webhooks as complementary, and verify any signature scheme documented in the dashboard when events are enabled for your account.
