# PPI Webhooks

> Index of prepaid instrument (PPI) wallet webhooks, including credit events, wallet notifications, and HMAC verification for JSON payloads.

PPI (wallet) integrations use webhooks for asynchronous outcomes such as wallet credits. Payloads include **`event_type`** and a **`signature`** field; follow the dedicated verification guide before processing money movement. For general webhook reliability guidance, see the [Cashfree webhooks overview](/docs/api-reference/webhooks/overview).
