Setting first, filter second

Both values are configurable without code on Mobile App Manager → WooCommerce Settings → Delivery. The filter is applied on top of the setting, so code overrides always win:

A blank/unset setting keeps the default shown above.

mam_wc_delivery_store_post_parent

Signature

apply_filters( 'mam_wc_delivery_store_post_parent', int $parent_id );

What it does

When a store/location is added from the app’s map form (WC Delivery Location Map → Add), the new mam-cpt-main post is created as a child of this post. The default 137 is the parent from the original deployment; if the resolved parent post does not exist on the current site, the plugin fail-safes to 0 (no parent) after the filter runs. Note the map list only shows posts with a non-zero parent, so pick a real parent post on sites that use the map.

add_filter( 'mam_wc_delivery_store_post_parent', function ( $parent_id ) {
    return 421; // this site's "Stores" container post
} );

mam_wc_delivery_image_sizer_url

Signature

apply_filters( 'mam_wc_delivery_image_sizer_url', string $sizer_url );

What it does

In the WC Delivery Location Map list, a location’s featured image larger than 800px in either dimension (png/jpg/jpeg) has its URL rewritten to <sizer_url><original image URL> so the app downloads a downscaled copy. White-label sites should point this at their own resizing endpoint via the setting, or disable it:

// Disable remote resizing entirely; serve originals.
add_filter( 'mam_wc_delivery_image_sizer_url', '__return_empty_string' );
