Using Gravity Forms ‘gform_helpscout_conversation’ PHP filter

The gform_helpscout_conversation Gravity Forms PHP filter allows you to modify the Help Scout conversation before it’s created.


To apply this filter to all forms:

add_filter('gform_helpscout_conversation', 'your_function_name', 10, 4);

To target a specific form, append the form ID to the hook name:

add_filter('gform_helpscout_conversation_1', 'your_function_name', 10, 4);


  • $conversation (array): Help Scout Conversation object.
  • $feed (Feed Object): Current feed.
  • $entry (Entry Object): Current entry.
  • $form (Form Object): Current form.

Change the conversation subject

This example changes the conversation subject to “Test Subject”:

add_filter('gform_helpscout_conversation', 'change_conversation', 10, 4);

function change_conversation($conversation, $feed, $entry, $form) {
    $conversation['subject'] = 'Test Subject';
    return $conversation;

Attach a file created from a Paragraph field value

This example attaches a file created from a Paragraph field value to the conversation:

add_filter('gform_helpscout_conversation', function($conversation, $feed, $entry) {
    $report = rgar($entry, '28'); // Get the field value.

    if (!empty($report)) {
        // Attach the file to the first thread (index 0 in the array).
        $conversation['threads'][0]['attachments'][] = array(
            'fileName' => 'system-report.txt',
            'mimeType' => 'text/plain',
            'data'     => base64_encode($report),

    return $conversation;
}, 10, 3);

Add custom field

This example adds a custom field to the Help Scout conversation:

add_filter('gform_helpscout_conversation', function($conversation, $feed, $entry, $form) {
    $conversation['fields'][] = array(
        'id'    => 19680, // Custom field ID from Help Scout.
        'value' => gf_helpscout()->get_field_value($form, $entry, '4'), // Get value from form field ID 4.

    return $conversation;
}, 10, 4);
