Marketing Automation API Integration
Marketing automation platforms manage email campaigns, customer journeys, lead scoring, and multi-channel marketing workflows. Integrating your application with your marketing automation platform ensures customer data flows automatically — triggering the right messages at the right moments in the customer lifecycle.
Core Integration Use Cases
- Contact sync: New customers, trial sign-ups, and leads flow automatically to the marketing platform — no manual export/import
- Lifecycle triggers: Application events trigger marketing journeys — onboarding sequences, re-engagement campaigns, upsell flows based on product usage
- Custom properties: Sync application data as contact properties — plan type, usage level, last login, feature adoption — enabling sophisticated segmentation
- Unsubscribe sync: Marketing unsubscribes must sync back to your application — suppression lists must be respected across all channels
