Outbound Communication Guidelines
To ensure the security, reliability, and proper functioning of outbound integrations or workflow webhooks in Zenduty, customers must adhere to the following guidelines when configuring their endpoints:
✅ Allowed Configuration
- Use HTTPS (Port 443):All URLs must use HTTPS and the default port 443.
- Example (valid): https://api.example.com/api/webhook/
❌ Not Allowed
- Custom Ports in URLs:URLs specifying ports other than 443 are not supported and will be considered invalid.
- Example (invalid): https://example.com:8000/api/webhook/
- IPv6-only Domains:Domains that resolve only to IPv6 addresses are not allowed. Domains must be either IPv4-resolvable or support dual-stack (both IPv4 and IPv6).
- Private IP Address Resolution:If the provided domain resolves to a private IP (e.g., 10.x.x.x, 192.168.x.x, or 172.16.x.x–172.31.x.x), it will be considered invalid.
🔔 Notifications and Compliance
- Customers currently using ports other than 443 will receive notifications prompting them to update their webhook configurations accordingly.
