Sept 8, 2025 Release
- Added Bulk OrdinanceStatusRollup endpoint.
A new endpoint lets you quickly check whether sources have been changed since a given timestamp. This is especially useful if your application stores local copies of sources and needs to keep that data up to date.
A new API feature is now available to link matching persons across FamilySearch trees. See the Tree to Tree Linking guide to learn more. This feature is in beta, and the interface may change over the next 60 days.
We’re excited to announce the launch of a modernized API Reference experience on the FamilySearch Developer website. This update is designed to make it easier than ever for developers to explore, understand, and interact with the FamilySearch API.
Implement tree to tree match endpoint.
