Rename from 'acf' in JSON

[anomaddev]

Is there a way to edit how the acf fields show in the JSON listing? For example I do not want my custom field to show under the field 'acf' but something custom. With the old plugin I was able to find how to change this but with V2 I am unable to find where this is set.

Hi @justinackermann,
you should use the filter "acf/rest_api/{type}/get_fields".

The wildcard {type} can be: post, page, user, term, comment, attachment, options or custom_post_type ( book )...

Thanks

add_filter( 'acf/rest_api/{type}/get_fields', function( $data ) {
    if ( method_exists( $data, 'get_data' ) ) {
        $data = $data->get_data();
    } else {
        $data = (array) $data;
    }

    if ( isset( $data['acf'] ) ) {
        $data['key'] = $data['acf'];
        unset( $data['acf'] );
    }

    return $data;
} );

I think you misunderstood me or I am misunderstanding you. Currently my json is for example:
acf: { field_title: "data" }

I would like it to be something like:
custom_naming_scheme: { field_title: "data" }

For mapping purposes on external sources I do not want to use the 'acf' naming.

    } else {
        $data = (array) $data;
    }

    if ( isset( $data['acf'] ) ) {
        $data['custom_naming_scheme'] = $data['acf'];
        unset( $data['acf'] );
    }

    return $data;
} );
