# TeXML Call Answered

`POST TexmlCallAnsweredWebhook` (webhook)

Webhook sent when a TeXML call is answered.
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.
