This Joomla user API will return users details based on search criteria

Common API Structure

APIs has the following characteristics:

• REST based (JSON over HTTPS)

HTTP Methods

The APIs follow the standard HTTP methods to bind to operations as follows:

• GET - Read only operations, one or more resources
• POST - Create Operation, insert a particular resource
• PUT - Update operation (e.g. update student data)
• PATCH - Partial update of an object (only given fields are updated)
• DELETE - Delete the object and return current state

Status Code

The APIs differentiate between HTTP status code and the result of the operation. Successful execution of the API returns HTTP response code 200. In a case of failure, the response body contains JSON encoded error details with the appropriate error code as listed below. In general, the APIs do not go down to fine-grained status code (e.g. to differentiate between 200 - success and 201 - created).

• 200 - Completed successfully (results may contain warnings, but no errors)
• 400 - Client side error - client may fix the error (e.g. bad data) and retry
• 404 - Resource not found - when a particular object ID is invalid
• 500 - Server-side error - client need not retry the request, most likely it will fail again

The response body contains appropriate error details even in a case of 400 or 500 responses, indicating the exception encountered:

The API has the following resources:

• v3/users (for search/browse)
• /v3/users/:id (for user details)
• /v3/users/create (for creating a new user)
• /v3/users/update (for updating a new user)

Method - POST [ Internal URL ]

• Endpoint - index.php?option=com_api&app=users&resource=user&format=raw

This API takes optional parameters for 'limit' to control the number of results to be returned. Additional search filters can be specified with the request and matching results are returned.

2. Number fields
