Webhooks
Trusted IP allowlist for webhooks
Use Straddle’s published IP allowlist to restrict inbound webhook traffic to your endpoints, ensuring secure communication for ACH event notifications.
In case your webhook receiving endpoint is behind a firewall or NAT, you may need to allow traffic from Straddle’s IP addresses.
This is the full list of IP addresses that webhooks may originate from grouped by the region of the sender.
The list is also available as a JSON file: webhooks-ips.json.
