Platform IP Addresses

Outbound IP Addresses

When Publica.la connects to your external services (authentication APIs, permission endpoints, or webhook receivers), all requests originate from the following IP addresses over HTTPS (port 443):

IP Address
44.219.135.50
3.218.91.65
100.51.119.83
2600:1f10:43f2:8300::/56

The 2600:1f10:43f2:8300::/56 entry is an IPv6 CIDR range: requests may originate from any address within it.

Allowlist all of the addresses above. Any of them can serve a given request, and we keep this page current as addresses are added or retired, so re-check it whenever a call from us is rejected.

When You Need This

If your infrastructure uses IP-based access control, you may need to allowlist these addresses. Common scenarios include:

• Permission APIs: Your server validates reading permissions for Publica.la users
• Webhook receivers: Your firewall restricts incoming connections by IP
• Authentication endpoints: Your identity provider allowlists third-party callers

Important Notes

• These IPs apply to all outbound requests from our platform, including background jobs and queue workers.
• All outbound traffic uses HTTPS (port 443).
• You can verify that requests from these IPs originate from Publica.la. If you receive requests from other IPs claiming to be our platform, please contact your account manager.
