This release introduces Building Extensions documentation, enabling developers to create and submit custom extensions for the Candescent Digital Banking platform — including support for Widgets (web) and Aspects (for web and mobile).

What's New​

Building Extensions guides​

The documentation includes comprehensive guidance on extension types, platform support, and the submission workflow through the Developer Console. Widgets are self-contained UI components built with the CDX extensibility SDK, providing access to user context, branding, and HTTP services; the documentation includes an overview, web SDK reference, platform capabilities, OLB integration details, and FAQ. Aspects are JavaScript files injected at runtime to customize the banking interface; the documentation includes an overview, technical references for web and mobile, examples, and FAQ. Local development for web widgets is supported through the web harness.

API documentation updates​

API reference documentation has been updated to reflect the latest OpenAPI specifications.
