Outbound API: connecting campaigns to external systems
Send data from a campaign to your CRM, CDP or any other tool, in real time.
14 April 2026 · OrchestrationYou can now connect your campaigns to external systems in real time using the new Outbound API block. When a customer triggers an event in your campaign, Nexus sends data directly to your CRM, CDP or any other tool. The customer journey continues beyond the platform.
Examples
A customer signs up → notify your CRM to trigger a welcome email
A customer completes a challenge → send their data to your CDP for a follow-up journey
A customer activates an offer → update their profile in an external system
What’s new
Trigger external actions from campaign events — send data to any external system the moment a customer reaches this step.
Dynamic payloads with placeholders — insert customer, event and purchase data into the request body using {{ placeholder.name }} syntax with autocomplete.
Reusable authentication — save OAuth 2.0 or HTTP Basic credentials once in Segmentation → Integrations and reuse them across blocks and campaigns.
