Appian Cloud Integration

Appian provides different ways to integrate your applications with external systems.

Beyond assisting customers in the configuration of some of these integration points, changes to default product properties are not supported in Appian Cloud. Appian Cloud utilizes standard configuration settings that are the default for Appian.

Appian developers are required to design their applications to work within those specifications rather than requesting custom settings to circumvent suboptimal design patterns or poor performing system integrations. The only changes to settings allowed are those that are exposed via the web browser via the Admin Console.

Design considerations

When integrating Appian Cloud with external systems, know which attributes can change without prior notice and which remain constant. To implement a robust integration, avoid dependencies on variable attributes.

Attribute	Type	Details
IP address of VPN gateway	Fixed	If a VPN gateway is configured for an Appian Cloud environment, the IP address of each VPN gateway is fixed.
Environment URL	Fixed	The URL to access an Appian Cloud environment will not change unless the change is exclusively requested by Appian customers.
IP addresses	Variable	Other than the IP address of the VPN gateway (if VPN is configured), all other IP addresses related to Appian Cloud (including email servers) are subject to change at any time and should not be directly referenced. DNS records should always be consulted to get the current IP addresses being used.
SSL certificates	Variable	Default SSL certificates used for Appian Cloud environments are managed by Appian and renewed routinely. Appian may replace these certificates at any time and without prior notice. Systems integrating with Appian should not rely exclusively on cached certificates and should not pin these SSL certificates or their chain of trust, as it could lead to connectivity issues when a new SSL certificate gets deployed. If you must pin the SSL certificate or chain of trust for your environment, we recommend configuring a custom domain using your own SSL certificates.
