Goodstack

Goodstack (formerly Percent) is an impact platform whose REST API lets businesses build charitable giving, nonprofit verification, and fund disbursement into their own products. The Goodstack Services API covers monetary donations (direct and via a hosted donation gateway), a global registry of verified nonprofit and educational organisations, organisation name search, eligibility and monitoring subscriptions, agent verifications, validation requests and submissions, Gift Aid declarations, categories, and webhook subscriptions. Goodstack handles the vetting, validation, and timely disbursement of donations to good causes across multiple countries and currencies. The API is organised around REST, uses API-key authentication (publishable pk_ and secret sk_ keys), returns JSON with standard HTTP status codes, and offers a sandbox environment.

Goodstack publishes 21 APIs on the APIs.io network, including Activities API, Agent Verifications API, Categories API, and 18 more. Tagged areas include Company, Non-Profit, Donations, Charitable Giving, and Fundraising.

The Goodstack catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Goodstack’s developer surface includes sandbox, changelog, authentication, documentation, API reference, getting-started guide, support, and 22 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Payments regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/goodstack: open an issue to ask a question, or submit a pull request to add artifacts.
