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 |
|---|
54.156.183.195 |
54.235.200.172 |
These IP addresses are scheduled to change in Q2 2026 due to an infrastructure migration. We will notify affected customers in advance with the new addresses.
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.
