Apinizer API Creator is a low-code solution for building REST APIs and microservices. With Quick and Easy development, you can create secure, low-cost, manageable, and easy-to-maintain REST APIs and Services.

For example, these data sources can be SQL databases, Big Data databases, code libraries such as JavaScript, Groovy, or Mock Responses.

Apinizer API Creator minimizes your development time along with the ease and efficiency of modernizing application architectures.


By connecting to your database and using the GET, POST, PUT and DELETE methods, you can create your REST API from different data sources for each endpoint, if you want. Use SELECT, INSERT, UPDATE, DELETE, PROCEDURE CALL, BATCH INSERT operations to endpoint your REST APIs.

With the DB-2-API, Apinizer allows even non-programmers to create and install an API that performs database operations in minutes. It supports the following operations:

  • Native SQL statements
  • Calling Stored Procedure
  • Return the cursor result
  • Batch processing
  • CRUD operations

For more information on how to create and customize your REST API with DB-2-API, see DB-2-API. Creating a REST API with DB-2-API.

Mock API

It is a tool that allows you to easily and quickly create and perform operations on REST APIs that return a response in accordance with response, header and conditions. You can use MockAPI as a prototyping, testing or learning tool.

For more information on how to build and customize your REST API with MockAPI, see MockAPI. Creating REST API with Mock API.


REST API built with script codes allows application developers to create custom REST APIs. You can define Groovy or JavaScript to manage Request and Response as well as service endpoints, query parameters and headers for a scripted REST API. Access the document of your Rest APIs you created in OpenAPI 3.0.x format as on the fly.

With the Script-2-API, Apinizer allows users to instantly open an API by typing JavaScript or Groovy code (or pasting existing ones). It is also possible to use desired parts of request/response messages within the code. Thus, there is no need to set up a server for the API to be put into service, and the API can be put into service within minutes.

The documents of the created REST APIs in Swagger and OpenAPI formats can be accessed on the fly in JSON and YAML types.
