Protocols

Beeceptor is a multi-protocol mock server that helps you simulate APIs across different technologies. You can import an OpenAPI specification, provide a GraphQL SDL, connect to a WSDL endpoint, or link a gRPC service. Beeceptor uses schema reflection to automatically fetch definitions and generate a ready-to-use mock server. Each mock endpoint is enriched with AI-generated, contextual, and meaningful test data, giving you a consistent and realistic experience from the start. Explore the following guides to learn how to set up each protocol.
