# Replaced Link Click

`POST replacedLinkClick` (webhook)

This webhook uses Telnyx headers (telnyx-timestamp, telnyx-signature-ed25519) that are compatible with Standard Webhooks specification for SDK generation. Custom validation logic can map these to standard webhook-timestamp and webhook-signature equivalents. See https://github.com/standard-webhooks/standard-webhooks for details.

## Headers

- `telnyx-timestamp` integer, required — Unix timestamp for replay attack prevention
- `telnyx-signature-ed25519` string, required — Ed25519 signature of timestamp|payload for verification

## Payload

- ReplacedLinkClickEvent
  - `data` ReplacedLinkClick
    - `message_id` string, uuid — The message ID associated with the clicked link.
    - `record_type` string — Identifies the type of the resource.
    - `time_clicked` string, date-time — ISO 8601 formatted date indicating when the message request was received.
    - `to` string — Sending address (+E.164 formatted phone number, alphanumeric sender ID, or short code).
    - `url` string — The original link that was sent in the message.

## Acknowledgement `200`

The server must return an HTTP 200, otherwise we will reattempt delivery at the failover webhook URL.
