CrossEngage
CrossEngage is a Berlin-based customer data and cross-channel marketing platform (a Customer Data Platform / CDP) founded in 2015 and backed by Earlybird Venture Capital. It unifies first-party customer data into 360-degree profiles, builds no-code predictive AI/ML models for customer lifetime value and behavior, manages audiences with drag-and-drop segmentation, and orchestrates real-time cross-channel customer journeys across email, push, SMS, WhatsApp and webhooks. Following its acquisition by Spotler, the product is sold as Spotler Activate Pro. CrossEngage exposes six REST APIs on api.crossengage.io — User Management v1 and v2, Product Feed, Raw Export, Statistics and File Attachments — totalling 37 operations. Five are published as API Blueprint documents and one (Product Feed) as Swagger 2.0, all served from Apiary and embedded in the reference site at api.documentation.crossengage.io. Authentication is a static X-XNG-AuthToken header paired with a required X-XNG-ApiVersion header; there is no OAuth surface. Product documentation is published at documentation.crossengage.io, which serves a first-party llms.txt index of all 219 pages.
CrossEngage publishes 6 APIs on the APIs.io network, including User Management API v2, User Management API v1, Product Feed API, and 3 more. Tagged areas include Company, Customer Data Platform, Marketing, Customer Engagement, and Marketing Automation.
The CrossEngage catalog on APIs.io includes 1 event-driven AsyncAPI specification.
CrossEngage’s developer surface includes authentication, documentation, API reference, pricing, engineering blog, support, getting-started guide, and 27 more developer resources.
