Embed crypto donations on your own site

A lightweight REST API for nonprofits and partners who want to collect crypto donations without redirecting donors away.

Overview

The Donations API lets an approved nonprofit or partner create a donation intent, receive a deposit address for the donor's chosen coin, and get notified when the transaction confirms on-chain. It's the same flow that powers the donation form on this site.

Authentication

API access is issued per approved partner — see For Nonprofits to apply. Once approved, requests are authenticated with a bearer token in the Authorization header.

Create a donation

  "amount": "25.00",
  "donor": {
    "email": "donor@example.com",
    "name": "Jane Donor"
  }
}

  "id": "don_8f2a1c",

  "network": "solana",
  "deposit_address": "YOUR_SOLANA_ADDRESS_HERE",
  "expected_amount": "25.00",
  "coin": "USDC-SOL"
}

Webhooks

Once a donation confirms on-chain, we send a signed donation.confirmed event to your configured webhook URL so you can update your own records in real time.
