# 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 · Orchestration*

You 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.

![A flow on the canvas: a challenge, an Activity event block set to Completed, and an Outbound API block named CDP - Challenge Complete, with Outbound API highlighted in the Block library](https://mintcdn.com/lobyco-4c9fb3ad/8XKQyo6M7ttG0QMR/images/release-notes/2026-04-14-outbound-api-connecting-campaigns-to-external-systems-01.png?fit=max\&auto=format\&n=8XKQyo6M7ttG0QMR\&q=85\&s=6d36af2f655bc3d521ba852a89dad98c)

## 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.

The Outbound API block is available in the **Orchestration view** toolbox for all real-time event-based campaigns.
