Beeceptor

    Give superpowers to API developers!

    Beeceptor is not just an API mocking tool. It take your API development, integration, verification and debugging experience to next level. Thousands of developers are using it and being productive each day.

    Build Mock APIs - Superfast!
    Get your mock API endpoint up and running in seconds - No Coding Required. Just define API path, response and start hitting the endpoint.
    Learn about mocking rules
    Reverse Proxy - Intercept & Inspect
    Wrap your existing API endpoint with Beeceptor sub-domain and inspect all the traffic going to the original domain. Beeceptor acts as a proxy-server and helps in inspecting headers and body for HTTP requests.
    Discover Reverse Proxy
    Proxy Mode - Mock or Forward
    When you use proxy mode, you can use rules to mock a few requests and forward the rest to target domain. If no rules are matched, the request is forwarded to original target and your application works as usual.

    CORS Friendly (preflight requests)
    Beeceptor, comes with CORS support and all origins are accepted out of the box.

    Access-Control-Allow-Origin: *
    OPTIONS calls will get '200 OK' always.
    Webhook Development
    Either you are consuming a webhook or building one, you shall need to inspect and debug HTTP calls. Get 200 OK.

    E.g. Shopify, Stripe, Zoho, Sendgrid, Jira, Gitlab, PipeDream, IFTTT, Zapier, etc.
    Local Tunnel - Expose to the world!
    Beeceptor's Local Tunneling lets you easily bind a web service on your localhost to a Beeceptor's endpoint. All the requests hitting the Beeceptor will be routed to a local port and response is served to the caller.

    Simulate latencies & timeouts
    Simulate higher latencies by introducing delays and timeouts to the mocking rules. Helps you validate rarely reachable code paths.
    Use Beeceptor APIs
    Use Beeceptor APIs and manage mocking rules programmatically in your CI tests. Validate if the mocked request received required parameters.

    Bring Your OAS Spec!
    Beeceptor takes your OpenAPI Specification to next level by hosting a mock server with just one click. You can now upload the specification file to an endpoint and start serving requests.

    Mock Downstream Services
    Consider you are working on API 'A', and downstream micro-services are 'B' and 'C. Beeceptor can help you mock B and C to test paths that were not possible before.

    E.g. when API-B times-out or erred, how does API-A behave?
    Dynamic Mocked Response
    Use fake data generators and get a near to real mocked response.
    Using Templates Variables
    Share a request/response sample
    An intercepted request can be shared with peers easily. Get a unique permanent link to share with your peers.

    Requests logging
    Search and review all the captured requests and responses. You can filter these by the response-code or request-path to drill down. The requests are available and searchable for 10 days.

    Single Page Application - SPA
    One great usage is during SPA development. You need first few ajax request to initialize the page and later mocking new calls. Beeceptor can route requests to original target without breaking your flow.
    Load Testing an API
    When your API consumes 3rd party APIs, load testing is difficult. Just wrapping an 3rd party API and enable/disable rules helps here. E.g. sending a transactional emails when your API is called - why not mock Sendgrid/SES/MailGun/PostMark APIs.
    Production vs New Code
    You can switch the target endpoint anytime. This helps you validate a test against deployed code vs new code in development. E.g. does this GET call return same data for new vs old code?
    UI Development
    Is the data contract ready between UI and API developer? Just mock the response and unblock UI developers.
