Wordpress plugin that autenticates an API and displays data

Creating a bespoke plugin that authenticates a user in Wordpress, generates an Authentication token from the API login route, and produces shortcodes that display product information. This plugin is a proof of concept for now so doesn't have to look pretty, but will need sensible, readable code.

I am a web developer myself, so will not accept poor quality work. I simply don't have capacity to take on this project. I will need this plugin finished as soon as possible.

The API has the following routes:

Call All Users
Call Specific Users
Post User
Login
Call Get Products

The API uses JWT to authenticate requests, and produces a JSON output.

I would like the plugin to list the products via a shortcode on the front end and display in a flex grid, and demonstrate querying the other routes from the API in shortcodes too (these can just output a list for now).

Within WordPress, the user should be able to enter their login details (username + password), and JWT tokens will be generated to request from the API on the front end.

This will be an ongoing project with more development in the future.

Documentation will be given to the accepted candidate.
