Overview

HubSpot App Marketplace lets developers connect their products to HubSpot's CRM platform. Apps use OAuth 2.0 for workspace-level authorization and can embed cards in CRM records, workflows, and the sidebar.

How to build & ship

  1. 1Create a HubSpot developer account and register a public app
  2. 2Implement the OAuth authorization-code flow and request only the scopes the app actually uses
  3. 3Build against the supported platform/API version and wire up webhooks plus the Uninstall App endpoint
  4. 4Reach the listing bar: installs in separate accounts and all declared scopes exercised recently
  5. 5Add privacy policy, terms, setup page URLs and a demo video, then submit for listing review
  6. 6Pursue certification later (sustained active installs plus a security questionnaire)
