Below, I will explain all the steps and how everything works so you get a better understanding of what I’m trying to achieve.

• The import_employees function kicks off and grabs the $settings['page'] = 1' which is the first page.
• Then once the script finishes, it increments the current_page if the next_page is not null and restarts the script with the next batch of 500 until it reaches the last page and then resets the current_page to 1.

Does anyone know what I might be doing wrong? All the info provided will be helpeful.

var_dump($records) reveals the following information:

object(stdClass)[1336]
  public 'paginator' => 
    object(stdClass)[1335]
      public 'total' => int 3081
      public 'per_page' => int 500
      public 'current_page' => int 1
      public 'last_page' => int 7
      public 'prev_page' => null
      public 'next_page' => string 'https://oc.com/api/v1/employees/?page=2' (length=61)

var_dump($next_page); reveals the following:

array (size=3)
  'page' => int 2
  'started' => int 1572849045
  'finished' => int 0

Full code is listed here:

function import_employees()
{
    $log = [];
    $start_script = false;
//    $name = 'octopus_import_employees';
    $settings = get_settings();
    $octopus = get_octopus();

    /* Start the script at 0 */
    $settings['started'] = 0;
    $settings['page'];

    /* If the started timestamp is less than or equal to finished, start the script */
    if ($settings['started'] <= $settings['finished']) {
        $start_script = true;
    }

    /* If start script is true, continue */
    if ($start_script) {

        /* Grab the first 500 records from Octopus */
        $records = $octopus->get_raw('employees', [
            'updated_at_after' => $settings['started'],
        ]);

        /* Once the time is fixed, if no records need updating */
        if (!$records) {
            echo '<pre>No updates for offices in Octopus.</pre>';
            return;

                $wp_employee = get_id($record->id);

                /* Grab the sync settings */
                $sync_settings = get_post_meta($wp_employee->ID, '_setting_update', true);

                /* Change WP last modified timestamp to Unix */
                $wp_modified = strtotime(get_post_meta($wp_employee->ID,'_last_modified', true));
            }
        }

        if (!is_null($records->paginator->next_page)) {

            $settings['finished'] = time();
        }
    }
}

function get_settings()

    /* Set the default page, started and finished */
    return [
        'page' => 1,
        'started' => 0,
