## About phpList
phpList is an open source newsletter manager.
## About this package
This module is the REST API for phpList 4, providing functions for superusers
to manage lists, subscribers and subscriptions via REST calls. It uses
functionality from the `phplist/core` module (the phpList 4 core).
It does not contain any SQL queries, uses functionality from the new core for
DB access.
This module is optional, i.e., it is possible to run phpList 4 without the
REST API.
This new REST API can also be used to provide REST access to an existing
phpList 3 installation. For this, the phpList 3 installation and the phpList 4
installation with the REST API need to share the same database. For security
reasons, the REST APIs from phpList 3 and phpList 4 should not be used for the
same database in parallel, though.
## Installation
Please install this package via Composer from within the
[phpList base distribution](https://github.com/phpList/base-distribution),
which also has more detailed installation instructions in the README.
## Local demo with Postman
You can try out the API using pre-prepared requests and the Postman GUI
tool. Install Postman as a browser extension or stand-alone app, open the
[phpList 4 REST API Demo collection](https://documenter.getpostman.com/view/3293511/phplist-4-rest-api-demo/RVftkC9t#4710e871-973d-46fa-94b7-727fdc292cd5)
and click "Run in Postman".
