Airtable webhooks

Notifications that a base changed. The ping has no data; call the webhook payloads endpoint to read the changes.

Events

tableData changes
tableFields changes
tableMetadata changes

Signature

Header X-Airtable-Content-MAC: 'hmac-sha256=' + HMAC-SHA256 of the raw body with the webhook's MAC secret (base64 decoded), hex encoded.

✓ A bin checks Airtable signatures: add the MAC secret (base64) under Signature verification (Airtable).

Retries

Airtable retries the ping with backoff, and the payloads stay available for 7 days.

See a retry schedule in the calculator.
