What is it?
The Veloxio API Mock Service is a hosted platform that creates fully functional simulated APIs in seconds. Whether you're mocking a RESTful microservice, a legacy SOAP endpoint, or an XML data feed, you get a live URL your team can call immediately.
Unlike static JSON fixtures, Veloxio mocks are dynamic — they understand your request parameters and return contextually appropriate responses. When your API contract evolves, mocks update automatically without manual intervention.
Multi-project workspaces mean you can manage dozens of services for multiple teams, with fine-grained access control and environment separation.
How It Works
From API spec to live mock endpoint in five straightforward steps.
Import or Define
Import an OpenAPI/WSDL spec or define your API contract from scratch in the UI.
Configure Mocks
Set up dynamic responses with conditions, delays, and parameter-driven logic.
Publish Endpoint
Get an instant live mock URL that your team or CI pipeline can hit immediately.
Auto-Update
When your API contract changes, responses update automatically — no manual edits.
Connect & Integrate
Link the mock to your other Veloxio products or external tools via connectors.
Supported API Protocols
One platform, every protocol your stack needs.
REST API
GET, POST, PUT, PATCH, DELETE — full resource mocking with status code control.
SOAP API
Import your WSDL and get a functional SOAP endpoint that returns well-formed XML responses.
XML API
Template-driven XML responses for legacy integrations, EDI feeds, and XML data services.

Who Is It For?
Frontend Developers
Develop UI features against realistic API mocks before the backend is ready — no more waiting.
QA Engineers
Test edge cases (timeouts, errors, empty states) by controlling mock responses precisely.
Platform Teams
Isolate third-party dependencies in integration tests without hitting live vendor APIs.
