Creating an endpoint in wordpress

I'm writing a plugin that will allow some of my installs to talk to each other and share specific information. I wish to specify an endpoint such that example/path/here is where the other site can GET some nicely formed XML or POST some nicely formed XML (depending on which way the data is flowing).

As a rough hack, I set up ./wp-content/plugins/myplugin/endpoint.php but I get the impression that direct calling is going to be bad. How do I do this the WordPress way?

• 1 @MatthewBrownakaLordMatt You can send the data as XML in JSON... {"myXml":"xml data here"} ... if it's not easier to just convert the data to JSON.. – Sally CJ Commented Jun 11, 2019 at 14:01
• 1 I'm coming round to JSON. Conversion is not so hard. – Matthew Brown aka Lord Matt Commented Jun 12, 2019 at 7:39

You can create a custom endpoint using the add_feed function. I have used this in the past to create custom iCal feeds.

// Initialize the feed
function your_add_custom_feed() {
    // This adds a feed http://example/?feed=myfeed
    add_feed('myfeed', 'your_create_feed');
}
add_action('init','your_add_custom_feed');

// Create a function to form the output
function your_create_feed() {

    // Query variables are accessible here ($_GET)
    $myvar = get_query_var('myvar');

    // You may need to specify the header before output here depending on your type of feed
    // header(...)

    // Echo your feed here.

}
