Allow webhooks by IP address
If you receive webhooks from seven, you can restrict incoming requests to our IP addresses. seven sends webhooks from several servers, so there are several addresses, both IPv4 and IPv6. Please always allow all addresses on the list.
Current list
The complete and always up-to-date list is in our API documentation. To keep your firewall updated automatically, it is also available in machine-readable form as JSON.
There you will also find the addresses for SMPP, in case your firewall restricts outgoing connections.
Changes
New addresses are added to the list at least 7 days before we start using them. Before an address is removed, we announce it in our Changelog.
In addition to checking the IP address, we recommend verifying the signature of every webhook. See the API documentation for details.
