# Announcement: New API Reference

We’re excited to announce the launch of a modernized API Reference experience on [the FamilySearch Developer website](https://developers.familysearch.org). This update is designed to make it easier than ever for developers to explore, understand, and interact with the FamilySearch API.

## Improved Search Capabilities

The site-wide search now includes endpoint operations in the results. Whether you're looking for how to “Update a Person” or “Read Relationships,” you’ll find it quickly and clearly.

## Organized by Operation

We've reorganized the API Reference around individual operations (e.g., [Read Person](https://developers.familysearch.org/main/reference/readperson), [Search Tree Persons](https://developers.familysearch.org/main/reference/searchtreepersons)), replacing the previous resource-based structure. This means you can now zero in on exactly what you want to do, faster.

## Try It! – Interactive Testing

Each operation page now includes a **"Try It!" feature**, allowing you to test API calls directly in the Beta environment. Just provide your access token, fill in the parameters, and run your request—all in the same place.

## JSON Schema Page

We’ve added a dedicated [JSON Schema](https://developers.familysearch.org/main/reference/json-schema) page that details the structure of the FamilySearch data model. This is your go-to reference for understanding how data is formatted across the API.

## Coming Soon

We’re actively working on integrating example requests and responses into each operation page. In the meantime, you can still find helpful examples in the **[Guides » Example Requests](https://developers.familysearch.org/main/docs/example-requests)** section.

We’d love to hear your feedback as you explore the new experience. Try it out and let us know what you think!
