Gravity Forms to CRM, WPML and ACF custom builds for a multilingual B2B site

add_action( 'gform_after_submission', function ( $entry, $form ) {
    $entry_id = (int) $entry['id'];

    if ( gform_get_meta( $entry_id, 'crm_synced' ) ) {
        return; // already pushed — retries are safe
    }

    $payload = [
        'email'     => rgar( $entry, '2' ),
        'firstname' => rgar( $entry, '3' ),
        'company'   => rgar( $entry, '4' ),
        'message'   => rgar( $entry, '5' ),
        'source'    => 'gform:' . $form['id'],
    ];

    $response = wp_remote_post( 'https://api.crm.example/v1/contacts', [
        'timeout' => 15,
        'headers' => [
            'Authorization' => 'Bearer ' . MY_CRM_TOKEN,

        gform_update_meta( $entry_id, 'crm_error', wp_remote_retrieve_body( $response ) );
        as_schedule_single_action( time() + 300, 'my_retry_crm_push', [ $entry_id ] );
        return;
    }

    gform_update_meta( $entry_id, 'crm_synced', time() );
}, 10, 2 );

The crm_synced flag keyed on the entry ID means a retry can never create a second CRM record, and failures go to a retry queue instead of vanishing.

function my_get_field_translated( string $selector, $post_id = null, $format = true ) {

One wrapper removed an entire class of "field is empty in German" bugs.

PHP registration plus JSON sync makes field groups diffable in git and impossible for an editor to delete.
