# Webhooks
> Subscribe to Cashfree KYC Link webhooks to track when customers open, complete, or fail verification journeys initiated through shareable KYC links.
Webhooks are event-based notifications that are received when a specific event related to the KYC verification occurs.
In rare cases, such as network retries, read timeouts, processing delays, or delivery failures, the same webhook might be sent more than once for the same event. To prevent unintended side effects, implement idempotency in your webhook handler to handle duplicate deliveries.

## Webhook signature
You will receive the webhook signature in the webhook header. Here is a sample header from a webhook request.
| Header name | Header value |
| ------------------- | :------------------------------------------: |
| content-length | 1099 |
| x-webhook-attempt | 1 |
| content-type | application/json |
| x-webhook-signature | 07r5C3VMwsGYeldGOCYxe5zoHhIN1zLfa8O0U/yngHI= |
| x-webhook-timestamp | 1746427759733 |
Always capture the webhook payload in its raw text format before parsing into JSON. Parsing and re-serialising the payload can change the structure (for example, array ordering, spacing, or `null` handling) and cause a signature mismatch during verification. Use the exact raw body string from the request when computing the signature.
## Webhook payload fields
The webhook payload contains important metadata in its top-level fields.
| Field | Type | Description |
| ------------ | -------- | --------------------------------------------------------------------------------------------- |
| `event_type` | `string` | Indicates the type of event that triggered the webhook. |
| `event_time` | `string` | The UTC timestamp of when the event occurred, formatted in ISO 8601 (`YYYY-MM-DDTHH:MM:SSZ`). |
| `version` | `string` | Indicates the webhook format being used. Default version is "v1". |
| `data` | `object` | Contains event-specific details related to this feature. |
Verifying the signature is mandatory before processing any response. Refer to [Signature Verification](/api-reference/vrs/webhook-signature-verification) for more details.
