How to update taxonomy custom field with wp_update_term()?

wp_update_term does not support custom fields so you will need to use update_term_meta instead.

This stores values like this:

update_term_meta( $term_id, $metakey, $metavalue );

Your code should look something like this:

update_term_meta( 41, 'clpr_store_url', $url);
update_term_meta( 41, 'clpr_store_aff_url', $url);
