Outgoing IP Addresses

If your systems require IP allowlisting for incoming connections from Showpass, use the addresses listed below. These IPs are used for all outbound API requests, webhooks, and third-party integrations initiated by our platform.

Current IP Addresses

34.83.8.110
34.168.12.250
35.230.81.80
35.230.119.67

Who Needs This?

You'll need to allowlist these IPs if you:

  • Use Authorize.net as your payment gateway
  • Have firewall rules restricting incoming API requests
  • Integrate with third-party systems that require IP allowlisting
  • Need to verify the source of requests from Showpass

Authorize.net Users

Important: If you use Authorize.net with fraud detection enabled, you must add these IPs to avoid transaction issues.

Configuration Steps

  1. Log into your Authorize.net account
  2. Navigate to Account → Fraud Detection Suite → Transaction IP Velocity Filter
  3. Add all four IPs to the IP Address Exclusion section
  4. Save your changes

Why This Matters

Without IP allowlisting, legitimate transactions processed through Box Office or high-volume sales may be flagged as suspicious and placed under review, requiring manual approval.

Best Practices

When configuring your allowlist:

Step Action
✅ Add all four IP addresses to ensure uninterrupted service
✅ Use CIDR notation if required (e.g., 34.83.8.110/32)
✅ Allow traffic on port 443 for HTTPS connections
✅ Test the connection after configuration
✅ Document the configuration for your team
