Plan, Build, Debug and Ship your next API 

Take your API specification from Postman to Production 
in under 30 minutes

An end-to-end guide on implementing an API from planning to production, including testing.
Get everything you need: Low-code IDE, database, step-by-step guide, code snippets, supporting material and a live production server.

 Forget tooling. Forget infrastructure. Focus on delivering your API. 

Building an API is difficult, but creating a high-quality one is even more difficult.
Our low-code approach uses Postman and Linx to deliver a flexible, comprehensive, fully documented, live API. 

Low-code API process

 4 Steps to take an API definition from Postman to Production  

1. Create your OpenAPI 3 specification

Postman Define API specification

Use Postman to define your API in OpenAPI 3.0. Postman includes a schema editor that helps you construct and validate your schema.

Open API specification

2. Create the API

Linx  Add a REST Service and import the OpenAPI specification 

Use the low-code Linx Designer to create a REST Service and import the OpenAPI specification to automatically create the API endpoints.

Linx IDE Designer

3. Implement the API logic

Linx Implement the API logic    Postman   Generate and run tests

Use the Linx Designer to implement the logic behind the endpoints. Common scenarios include calling databases, other APIs, or message queues. Generate tests in Postman and run them to validate the API.

Test In Linx and Postman

4. Deploy to live server and test 

Linx 1-click deploy to live server   Postman  Run tests

Deploy your API to the Linx Server (cloud or on-premise) with a single click. Run your tests in Postman to validate the live API. Use the Linx Server management interface to manage your API and view metrics, logs, and history.



Linx Application Server

 Deliver a rock-solid API at speed  

API development is complex. We’ve built a process to make it easier

Development  —

Quickly implement bespoke programming functionality and services

Security, message queues, databases – all included, just add your logic

Debug your logic in Linx, test your functionality in Postman

Host & manage  —

Host your production API with the Linx Server

Built-in API observability and management

Automatically generate API documentation

 Why use Linx? 

Visual, but still programming

The Linx Designer is a visual IDE that allows you to program and debug at a higher level. Using Linx is no different from working with low-level programming, except that it involves larger components, more visual assistance, and lots of pre-made server-side functionality. 

Extend & customise

Linx offers a wide range of pre-built programming components to interact with databases (SQL, Oracle, OLE DB, ODBC, Postgres, Mongo), files (XML, JSON, text, csv, PDF) and services (cryptography, message queues, timers) to integrate and extend your API.

Effortless hosting

With Linx, users can deploy directly to a dedicated server (on-premise or in the cloud). The Linx Server includes built-in monitoring, security, metrics, and logging as standard, allowing you to go from development to live deployment without worrying about cost, maintenance or additional infrastructure.

Take an OpenAPI specification, from Postman to live API 

Postman and Swagger have revolutionized the way you design APIs. With Linx, you can now take your API definition directly into production.

Can I connect to my database?
Linx can connect to MySQL, PostgreSQL, SQLite, MS SQL Server, Oracle, MongoDB, and any ODBC or OLE DB datasource.

Can I call other APIs?
Linx can call any REST or SOAP API and supports popular authentication schemes like OAuth2 and API key.

Can I use my own domain?
Yes. You can map your own domain name to APIs hosted by Linx.

Can I secure the API?
Yes. Linx supports popular authentication schemes like OAuth2 and API key.

Can I run my API on-premise?
Yes. Linx Server can be deployed on-premise.
