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.

📄️ Rest API server from OpenAPI

Get a mock server from your OpenAPI spec in seconds. Beeceptor’s AI-powered mock server + Intelligent Mock feature auto-generates test data. See it in action with real examples.

📄️ GraphQL server from SDL

Instantly create intelligent, AI-driven GraphQL mock servers from SDL or introspection. Ideal for frontend, QA, and API testing workflows.

📄️ SOAP server from WSDL

Build intelligent SOAP mock server from WSDL. Beeceptor's uses AI to build contextual test data. Inspect all operations with dynamic request/response envelopes. No code, fast setup, AI-powered test data.

📄️ gRPC server from Proto

This page gives detailed feature documentation for Beeceptor's gRPC mock server, step wise guide, how to, limitations, creating a new behavior to override response, AI generated test data, etc.

📄️ Mutual TLS server

Build a mock server with Mutual TLS authentication. Enable client-server certificate validation, generate signed certs, etc. Create mock behavior for testing and simulation.
