Truto handles the OAuth and API key auth flows for Campaign Monitor so your end users can connect their account (or an agency master account) through a hosted or embedded flow. Your backend only deals with Truto's unified connection token. ### Can we create and manage Campaign Monitor client sub-accounts via the integration? Yes. The integration exposes full client lifecycle tools including create_a_campaign_monitor_client, update basics, update PAYG or monthly billing, transfer credits, and manage admins and primary contacts — ideal for agency and multi-tenant provisioning patterns. ### Does the integration support custom fields on subscribers? Yes. You can create, update, and delete custom fields on any list via create_a_campaign_monitor_custom_field and related tools, then set those field values when creating or updating subscribers. ### How do we receive real-time events like unsubscribes or bounces? Campaign Monitor supports list-level webhooks for subscribe, unsubscribe, update, and bounce events. You can create, activate, deactivate, and test webhooks through the integration, and Truto normalizes delivery to your endpoint. ### Can we send transactional emails through this integration? Yes. Both Smart Transactional emails (designed in the Campaign Monitor UI and triggered with a JSON payload) and Classic Transactional emails are supported via campaign_monitor_transactional_smart_emails_send and campaign_monitor_transactional_classic_emails_send. ### What campaign engagement data can we pull back into our product? You can retrieve recipients, opens, clicks, bounces, unsubscribes, spam complaints, email client usage, and summary stats for sent campaigns, plus equivalent per-email metrics for automated journeys. ### How are Campaign Monitor's bulk operations like subscriber import handled? The campaign_monitor_subscribers_import tool supports batching up to 1,000 subscribers per request. Truto manages pagination on list endpoints so you can iterate large audiences without writing custom logic.
