Dynamic Mock Server

Create mock endpoints with conditional responses and inspect incoming requests in real time.

1Step 1

Create or Select Server

Create a new mock server or choose an existing one.

2Step 2

Configure Responses

Build endpoints and conditional responses.

3Step 3

Test the Same Server

Send requests and inspect results and logs in one place.

Step 1A: Create Mock Server

Start here

Step 1B: Select Existing Server

No servers yet

Complete step 1 first

Step 2A: Endpoint Builder

MethodPathStatus CodeDelay (ms)

Endpoint enabled

Response Body (JSON)Response Headers (JSON)

Conditional Responses

Complete step 1 first

Step 2B: Configured Endpoints

No endpoints configured

Add an endpoint in step 2 first

Step 3A: Request Tester

Test your mock server without leaving this page

MethodPath

Query String

Request Headers (JSON)Request Body

Create a mock server to start testing.

No response yet. Send a test request to inspect the response payload and headers.

Add an endpoint in step 2 first

Step 3B: Request Logs

0 request(s) • auto-refresh 3s

No requests captured yet

About

Creates temporary mock endpoints with custom responses, conditional behavior, and request logs. It helps front-end, QA, and integration teams unblock workflows before the real API is ready.

Accepted input

Creates a server first, then accepts endpoint paths, methods, headers, delays, response bodies, and optional conditional blocks. The built-in tester can call the generated endpoint directly from the browser.

How to use

Create or select a mock server in step 1.
Add an endpoint in step 2 with a method, path, status code, and response body.
Optionally add conditional response rules for query, header, or body-driven behavior.
Use step 3 to send a test request and inspect captured logs.

Tips

Condition blocks are useful for simulating error branches without creating duplicate endpoints.
Populate the response body from the Webhook Payload Builder when mocking event-driven systems.
