# Link Confirmation - Verify OTP

This webhook is triggered when a user submits the OTP to confirm care context linking. Validate the OTP generated during the [Link Initiation](/api-reference/user-app/abdm-connect/webhooks/discover-link-init) step. If valid, proceed to link the care contexts.

<Note>
  After validating the OTP, call the [On Link Confirm API](/api-reference/user-app/abdm-connect/care-contexts/discover/link_on_confirm) with the list of care contexts to complete the linking.
</Note>
