You can modify the WPGraphQL endpoint in code with the following:



<pre class="wp-block-code lang-php"><code>function my_new_graphql_endpoint() {
 return 'cutepuppies';
};

add_filter( 'graphql_endpoint', 'my_new_graphql_endpoint' );</code></pre>



This will change the graphql endpoint url from <code>/graphql</code> to <code>/cutepuppies</code>



This also updates the WPGraphQL settings page:

Add WP Admin Color Schemes to WPGraphQL

This snippet logs all WPGraphQL requests to the error log



<pre class="wp-block-code lang-php"><code>add_action( 'do_graphql_request', function( $query, $operation, $variables, $params) {
	error_log( wp_json_encode( [
		'query' => $query,

		'variables' => $variables,
		'params' => $params
	] ) );
}, 10, 4 );</code></pre>

Log WPGraphQL requests to error log

Labels on Post Types are not publicly exposed by WordPress. They are attributes for use in the Admin, and are treated with respect to proper access to the admin.



To see the labels, the user requesting them must be authenticated.



When a user requesting a&nbsp;<code>PostType</code>, these are the following fields that are by default allowed to be viewed by a public request:&nbsp;<a href="https://github.com/wp-graphql/wp-graphql/blob/develop/src/Model/PostType.php#L59">https://github.com/wp-graphql/wp-graphql/blob/develop/src/Model/PostType.php#L59</a>



You can use the&nbsp;<code>graphql_allowed_fields_on_restricted_type</code>&nbsp;filter to expose more fields publicly if you chose to do so:&nbsp;<a href="https://github.com/wp-graphql/wp-graphql/blob/develop/src/Model/Model.php#L287">https://github.com/wp-graphql/wp-graphql/blob/develop/src/Model/Model.php#L292</a>



<pre class="wp-block-code lang-php"><code>add_filter( 'graphql_allowed_fields_on_restricted_type', function( $fields, $model_name, $data, $visibility, $owner, $current_user ) {
	if ( 'PostTypeObject' === $model_name ) {
		$fields[] = 'label';
	}
	return $fields;
}, 10, 6 );</code></pre>



Before adding the filter:

Filter to add restricted field on Model

This snippet outputs the <code>$_SERVER</code> superglobal so we can see if the Authorization token is being passed to the server or not.



<pre class="wp-block-code lang-php"><code>add_action( 'init', function() {

	if ( is_graphql_http_request() ) {
		wp_send_json( [ 'server' => $_SERVER ] );
