Card SDK

The Card SDK lets partners and developers build custom workflow cards for DocFlow. You package a card as a partner app and upload it, or import it directly from GitHub.

Card SDK tab with Upload ZIP, GitHub Import and Submissions
The Card SDK — upload a partner app ZIP, import from GitHub, or review your submissions.

How it works

  • Download SDK Template — start from the official template that contains the expected structure.

  • Upload ZIP — the ZIP must contain app.json and a .docflowcompose/flow/ folder with the card definitions (max 10 MB). Upload & Validate checks the package before it is accepted.

  • GitHub Import — import a card definition straight from a GitHub repository.

  • Submissions — track the status of cards you have submitted.

Once validated and accepted, your custom cards appear in the Add Card library alongside the built-in cards.
