Trello Power-Ups extend Trello boards and cards with embedded, iframe-based capabilities and REST API integrations. Builders register a Power-Up in the Trello admin panel, define the capabilities their iframe implements (card badges, board buttons, card back-section), and use the Power-Up REST API client to obtain a user OAuth token from their public API key. The public API key alone grants no data access; the secret token obtained via the authorization flow does.
Distribution is comparatively lightweight: Power-Ups can be created and published as public without a multi-week security audit, though the public directory involves an approval step. Trello provides no native billing, so monetization is handled through third-party platforms — Optro and Salable both provide integrated licensing, subscription, and payment flows, acting as the billing and merchant-of-record layer. Choose Trello Power-Ups for a low-friction way to add board-level capabilities with a public directory presence, pairing with Optro or Salable if you intend to charge.
