Json2Rest is a lightweight WordPress plugin that turns named JSON data into a configurable REST endpoint.

It is useful for small WordPress powered projects that need to serve structured data to a frontend or another application without building a custom backend.

Features

  • Store multiple named JSON objects from the WordPress admin
  • Configure the REST route and query parameter name
  • Retrieve a specific JSON object with a GET request
  • Use the standard WordPress REST API namespace
  • Keep data managed inside WordPress with no external database required
  • Includes a simple admin interface for adding, editing, and removing JSON blocks

Requirements

  • A WordPress installation with REST API support
  • PHP with the WordPress functions used by the plugin

Installation

  1. Download or clone this repository.
  2. Copy the Json2Rest directory into wp-content/plugins/.
  3. Log in to WordPress and open Plugins.
  4. Activate Json To Rest API Plugin.
  5. Open JSON Settings in the WordPress admin menu.

Configuration

1. Configure the endpoint

Open JSON Settings and provide:

  • Parameter Name — the query-string parameter used to select a JSON object
  • REST Name — the endpoint path

For example:

Parameter Name: school
REST Name: schools

2. Add JSON data

Open JSON Settings → Fill JSONs, add a name for each data block, and enter valid JSON.

Example:

{
  "name": "University of Athens",
  "city": "Athens",
  "students": 42000
}

Save the data before requesting the endpoint.

API usage

The endpoint is available through the WordPress REST API:

GET https://example.com/wp-json/rest/v1/schools?school=athens

The value of school must match one of the JSON block names saved in the admin interface.

Example response:

{
  "name": "University of Athens",
  "city": "Athens",
  "students": 42000
}

The endpoint returns an error when the plugin has not been configured, the requested parameter is missing, or no matching JSON object exists.
