We are adding new webhook server IP addresses:
22.214.171.124/28 (that is,
126.96.36.199). If you manage a list of IPs that you expect Trello webhooks to come from, the list should be updated to include the new IP addresses.
All webhook request will come from one of the following IP addresses/subnets:
188.8.131.52 184.108.40.206 220.127.116.11 18.104.22.168 22.214.171.124 126.96.36.199/28
We continue to recommend that you check the
x-trello-webhook header included in each webhook request to validate that that the webhook came from Trello’s servers. For more on validating signatures, check out the Webhook Signatures section in webhooks’ documentation.
