Contracts, a feature in Apollo Studio's Enterprise plan, allow developers to create tailored graphs for different audiences by applying filters to a single unified graph. This enables organizations to provide varying levels of access and schema scoping for partners, public APIs, and client applications without losing the benefits of the unified graph. Contracts integrate seamlessly with other features of Apollo Studio, including Federation 2, which offers improved shared ownership models, enhanced type merging, and cleaner syntax. The feature includes new functionality such as contract launches, support for Federation 2 and tagging additional schema elements, filter previews, and improved error handling. To get started, developers can check out the documentation and migrate their source variants to Federation 2, with Enterprise trials available for those not on the plan.
