How to exclude specific REST API endpoints from being cached by WP Rocket?

Question

I'm using WP Rocket along with their helper plugin WP Rocket | Cache WP Rest API which allows caching of WordPress REST API endpoints.

I’ve added the following filter to allow REST API caching:

add_filter( 'rocket_cache_reject_wp_rest_api', '__return_false' );

Now it's caching API routes like:

/wp-json/wc/store/v1/cart

/wp-json/custom/v1/xyz

However, I want to exclude certain endpoints (for example, /wp-json/wp/v2/posts or /wp-json/custom/v1/sensitive-data) from being cached.

To exclude specific REST API endpoints from being cached by WP Rocket, you can use this in your functions.php:

add_filter( 'rocket_cache_reject_uri', function( $urls ) {
    $urls[] = '/wp-json/wp/v2/posts';
    $urls[] = '/wp-json/custom/v1/sensitive-data';
    return $urls;
});

This will skip caching for those endpoints, while everything else still gets cached normally.

Hope this will works you out!

hi, ur solution is not working. After adding this, WP-Rocket is not collecting any data from api

Yeah if it's not caching anything after adding that, maybe you’re missing this part: add_filter( 'rocket_cache_reject_wp_rest_api', '__return_false' ); That line tells WP Rocket to allow caching REST API in the first place Without it, nothing gets cached at all no matter what
