Fundraise Up

Fundraise Up is an online donation and fundraising platform for nonprofits that optimizes the digital giving experience to increase conversion and recurring revenue. Its REST API gives programmatic access to fundraising data - donations, recurring plans, supporters (donors), and an events audit log - so organizations can process offline and non-digital donations through their Fundraise Up account, combine them with online giving, and sync everything to CRMs, BI tools, and data warehouses. The API is resource-oriented, uses JSON-encoded request bodies, and authenticates with an API key over HTTP Bearer. Base URL is https://api.fundraiseup.com/v1.

Fundraise Up publishes 5 APIs on the APIs.io network, including Donations API, Donor Portal API, Events API, and 2 more. Tagged areas include Fundraising, Donations, Non-Profit, Payments, and Recurring Giving.

Fundraise Up’s developer surface includes authentication, documentation, engineering blog, and 8 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.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% 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/fundraiseup: open an issue to ask a question, or submit a pull request to add artifacts.
