APIs

Flexkit generates a GraphQL API from each deployed project schema. Studio also uses a same-origin application handler for its signed-in requests.

SurfaceAddress or locationUse
Hosted project GraphQLhttps://PROJECT_ID.api.flexkit.io/graphqlAuthorized data queries and mutations.
Studio application handlerYour app’s /api/flexkit/...Framework-managed Studio authentication and proxy requests.
Project MCPhttps://PROJECT_ID.api.flexkit.io/mcpOAuth-enabled AI client access.
Custom toolsYour app’s /api/flexkit/toolsSigned discovery and invocation by Flexkit.

Replace PROJECT_ID with the ID from Dashboard Settings → General. These endpoints use different authentication flows; a working credential for one is not proof that every other surface accepts it.

Start with authentication, queries, and tokens. Use Explorer to inspect the schema before constructing data operations.

For data-change notifications, configure outgoing webhooks. To extend Studio itself, use extensions. See the reference index for the documented integration surfaces.
