Here's a neutral and interesting summary of how to receive SMS in WordPress with a PHP plugin: Receiving SMS on a WordPress site is made possible by utilizing the WordPress REST API feature, which allows developers to interact with sites remotely. A PHP plugin named "Receivedx" is used to set up receiving SMS, where users can respond to incoming messages and handle two-way messaging. The plugin registers a custom endpoint using the `register_rest_route` function, which serves as a webhook for incoming messages. When a message is sent to the Twilio number associated with the WordPress site, the endpoint triggers a response with a default text, "Ahoy from WordPress". To test this setup, users can send an SMS to the configured phone number and receive the response back. This tutorial provides a basic example of how to integrate SMS functionality into a WordPress website using the REST API and PHP plugins.
