Developer Documentation

Everything you need to integrate with the FundraiserMax API. Build custom workflows, sync donor data, and connect AI assistants to your fundraising platform.

Versioning

The FundraiserMax API is versioned via the URL path. The current version is v1, accessed at /api/v1/.

Stability Guarantees

Within a major version (e.g., v1), we guarantee the following:

  • Existing endpoint paths will not change.
  • Existing response fields will not be removed or have their types changed.
  • New optional fields may be added to response objects.
  • New optional query parameters may be added to existing endpoints.
  • New endpoints may be added.

Breaking Changes

Breaking changes (removing fields, changing types, altering behavior) will only occur in a new major version (e.g., v2). We will provide at least 6 months of deprecation notice and run both versions in parallel during the transition period.

Note: Subscribe to the API Changelog for notifications about new features, deprecations, and version changes.
