Crowdfunding API for developers

Use Fundsurfer's Crowdfunding API and Community Share API to integrate your crowdfunding campaign details into your own website or app.

We use the API on the Big Screen site to display live project totals and to power our internal tools.

Community Shares API

List Community Share projects

Community Share project info

Community Share campaigns have a dedicated read-only JSON endpoint:

https://www.fundsurfer.com/api/community-share/[campaign id]/json

Example

https://www.fundsurfer.com/api/community-share/5172/json

This endpoint is intended for displaying Community Share campaign information on another website or application. It is publicly available for published campaigns and supports cross-origin requests.

Response

{
  "campaign": {
    "id": 5172,
    "title": "Ashton Court Mansion Community Share Offer",
    "organisation": "Ashton Court Mansion Trust",
    "intro": "<p>Campaign introduction...</p>",
    "url": "https://www.fundsurfer.com/community-share/ashton-court-mansion-community-share-offer",
    "short_url": "https://www.fundsurfer.com/node/5172",
    "api_url": "https://www.fundsurfer.com/api/community-share/5172/json",
    "status": "live",
    "start_date": "2026-10-01T00:00:00+01:00",
    "end_date": "2026-12-31T23:59:59+00:00",
    "days_left": 73,
    "image": "https://www.fundsurfer.com/sites/default/files/image.jpg"
  },
  "fundraising": {
    "currency": "GBP",
    "target": 100000,
    "raised": 25000,
    "remaining": 75000,
    "percent_raised": 25,
    "minimum_investment": 100,
    "maximum_investment": 25000,
    "community_shares": 20000,
    "donations": 5000,
    "combined": 25000,
    "backers": 84
  },
  "activity": {
    "updates": 6
  }
}

campaign.url is the permanent campaign alias. campaign.short_url uses a configured redirect when one exists; otherwise it falls back to the node/[id] URL.

The fundraising totals include linked donation campaigns where configured. Only campaign-level data is returned: investor names, contact details, comments, Stripe information, and individual payment records are not exposed.
