Salesforce and HubSpot connectors sync contacts and basic activity in both directions, but, as covered in more depth on our ActiveCampaign CRM page →, they typically don't carry full custom field logic or complex pipeline mapping without extra configuration. Pipedrive's integration is similar: real, native, built for a standard setup.
Shopify and WooCommerce integrations pull in order and customer data so automations can trigger off a purchase, and they're genuinely solid for a standard storefront. QuickBooks Online's integration mostly covers syncing contacts and basic invoice status, not deep financial automation, deal-to-invoice logic beyond that native sync is custom work (see the main ActiveCampaign page → for how we've built that).
Zendesk and Intercom integrations sync support ticket activity so an automation can react to a ticket status, useful for post-support follow-up sequences. Calendly, Zoom, and ManyChat integrations are mostly event-and-notification layer: a booked call or a completed webinar can trigger an automation, without deeper data sync beyond that.
