We are adding new webhook server IP addresses:
Additionally, we are deprecating
If you manage a list of IPs that you expect Trello webhooks to come from, the list should be updated to include these changes.
All webhook request will come from one of the following IP addresses/subnets:
126.96.36.199 188.8.131.52 184.108.40.206 220.127.116.11 18.104.22.168 22.214.171.124/28
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.
