Rename from 'acf' in response

[misfist]

I temporary need to use v1 of the REST API and would like to change acf to something else (say, custom_fields). Your explanation for v2 (airesvsg/acf-to-rest-api#41) worked exactly as expected. So, I tried to do something similar in v1 using the acf_to_wp_rest_api_{$this->type}_data filter.

But, I wasn't able to get it to work.

apply_filters( "acf_to_wp_rest_api_{$this->type}_data", $data, $object, $context );

Any guidance would be appreciated.

Hi @misfist,
please try it:

add_filter( 'acf_to_wp_rest_api_{type}_data', function( $data ) {
    if ( isset( $data['acf'] ) ) {
      $data['custom_fields'] = $data['acf'];
      unset( $data['acf'] );
    }

    return $data;
}, 10 );

The wildcard {type} can be: post | user | term | comment | attachment | options

Thanks
