# Locating parameter values

> How to find parameter values like campaign_mailing_id, subscription_list_id, and campaign_mailing_send_id in the Paubox Marketing web dashboard.

Some Marketing API endpoints require IDs that identify specific campaigns, subscription lists, or campaign sends. This page shows where to find each of those IDs in the Paubox Marketing dashboard.

<Tip>
  All IDs can also be retrieved programmatically. Campaign mailings, subscription lists, and send records all include their `id` in API responses.
