To build a VTEX IO GraphQL API, define type definitions in the graphql directory, implement resolvers in node/resolvers, and register them in the Service while applying @cacheControl and @auth directives for caching and security.

VTEX IO GraphQL APIs require schema definitions in the graphql directory and resolver implementations in node/resolvers. Resolvers are then wired into the Service entry point to match the defined schema fields.

Enforce authentication and caching in a VTEX IO GraphQL API by applying the @auth and @cacheControl directives directly within your schema definitions to secure mutations and manage data exposure.

Resolvers access data within the VTEX IO service context by using ctx.clients. This ensures that data retrieval correctly matches the schema fields and operates within the proper VTEX IO application environment.

Yes, this process validates that resolvers match schema fields. It enforces correct data exposure by ensuring resolvers are properly wired in the Service entry point and aligned with the GraphQL type definitions.

To expose a public product graph with protected mutations, define your GraphQL schema in VTEX IO and apply @cacheControl for data caching alongside @auth directives to secure the mutation operations.
