You need to invoke Appian interfaces from an existing web portal.

The preferred solution for invoking Appian interfaces from an existing web portal is to implement an embedded interface approach. Appian provides the ability to embed interfaces (such as forms or dashboards) within other web applications, allowing seamless integration and interaction with Appian functionality from within an existing portal.

Embedded Interface Approach Overview:

Appian interfaces can be embedded in other web applications using iframe technology or JavaScript, allowing users to interact with Appian processes without leaving the existing portal.

This approach is ideal when the goal is to provide Appian functionality within a different user interface while maintaining the user experience of the existing portal.

Why Not Other Options?:

A. Appian Site: While Appian Sites provide a customized user interface within Appian, they do not integrate with external portals.

C. Custom UI instead of Appian UI: Creating a custom UI bypasses the built-in capabilities of Appian, leading to increased development effort and complexity.

D. Headless solution: A headless approach typically involves using Appian as a backend service without a user interface, which is not suitable for this requirement.
