summary: >-
  GoFundMe Pro's client-side surface is embed-first: a JavaScript checkout library, embedded
  donation forms generated from Campaign Studio, a JavaScript SSO SDK and a first-party WordPress
  plugin. These are distinct from the server-side SDKs catalogued in packages/.

  description: >-
    Renders a hosted checkout form into the host page and returns the full transaction response to
    the calling application — minus sensitive payment information such as card or bank account
    numbers — including values reusable for later charges, voids and refunds.

  - Prefill donor fields (name, address, email, phone, employer, date of birth, participant)
  - >-
    Attach arbitrary application metadata to the transaction object via `transaction_meta_*` form
    fields, or pass-through-only values returned in the transaction response
  - Hide the built-in submit control and drive submission from the host page

- name: Classy Login JavaScript SDK

- name: Campaign progress / leaderboard components
  kind: reference-implementation
  description: >-
    Node + React reference components published as sample apps — a campaign progress bar and a
    fundraising leaderboard — that consume the public API. Instructional samples, not a supported
    component library.
  repositories:
  - https://github.com/classy-org/custom-progress-bar-sample-app
  - https://github.com/classy-org/custom-leaderboard-sample-app

gaps:
- No versioned, npm-published web-component or element library; embeds are script-tag loaders.
- >-
  The Classy Pay loader and its staging twin are still served from the legacy classy.org /
  stayclassy.org domains after the GoFundMe Pro rebrand.
