weclapp HubSpot integration via MARINI: Synchronize customers, articles, sales orders bidirectionally. Real-time, no-code, EU hosting.

Would you like to have consistent and accurate customer data in weclapp at all times without any IT projects? That’s exactly what MARINI is for.






















weclapp delivers cloud ERP with integrated CRM. However, many companies use specialized systems for marketing, e-commerce, or advanced CRM functions. This is exactly where integration comes in.
MARINI connects weclapp with your entire ecosystem: customers, articles, orders, and inventory synchronize in real time. Bidirectional, GDPR-compliant, and without installation in weclapp.
weclapp combines ERP and CRM in one platform. For many companies, this is the ideal starting point. But when marketing automation can do more than the integrated CRM, when the shop requires its own logic, or when external partners bring their own systems, integration becomes a necessity.
MARINI connects weclapp with these specialized systems. Customers, articles, orders, and invoices flow bidirectionally. Data quality remains high, duplicates are detected, and each system works with the data it needs.

weclapp integration is not an industry-specific topic — it is a process-driven one. That said, the concrete requirements vary considerably: in the financial sector, the focus is on compliance, KYC processes, and regulated data flows. In mechanical engineering and manufacturing, the priorities lie in partner sales, aftermarket processes, and complex customer structures with hierarchical relationships. In the media industry, it is subscriptions, reader engagement, and multi-channel distribution that drive integration needs. The following industry pages demonstrate how MARINI addresses these requirements in practice.
MARINI focuses on the larger weclapp customers with more complex integration requirements. The adapter is immediately operational, cloud connection with EU-only hosting is standard.
Native Connectors vs. Integration Platform. Native connectors link two systems point-to-point. This works for a handful of integrations. As soon as you want to connect three, four, or more systems, it becomes confusing. Each combination requires its own logic, its own error handling, its own monitoring. MARINI orchestrates all integrations centrally. You configure once, monitor centrally, and scale without effort.
Custom Development vs. Permanent Platform. Developing integrations yourself gives you maximum control. You write code that exactly meets your requirements. But APIs change, requirements grow, and eventually maintenance ties up resources that are needed elsewhere. MARINI takes on this burden. Updates, monitoring, error handling are part of the platform. You focus on your business, not on integration.
Generic iPaaS vs. Specialized Solution. Generic iPaaS platforms can theoretically connect anything. In practice, this means: You build the logic yourself. MARINI specializes in B2B systems. Customer matching, duplicate checking, bidirectional synchronization with conflict resolution are ready-made building blocks. You configure instead of programming.
Business-critical data deserves maximum reliability. At MARINI, security isn’t an add-on—it’s our lived standard. Our security architecture at a glance:
This keeps your central data infrastructure stable, protected, and scalable at all times. Together, we’ll find the right integration and tailor it precisely to your requirements.
In weclapp, typically Customers, Contacts, Articles, Quotations, Sales Orders, Invoices, Inventory, and Tickets are synchronized. Custom attributes are supported. MARINI can map all objects available through the weclapp REST API.
weclapp provides a REST API for all essential business objects. Webhooks enable event-based synchronization. The API documentation is easily accessible. MARINI uses this API directly, without installation in weclapp.
No, weclapp is a pure cloud solution with hosting in Germany. There is no on-premise option. MARINI connects weclapp via the cloud API with other systems, even if they run on-premise.
weclapp is typically the leading system for inventory management, orders, invoices, inventory levels, and accounting. Marketing activities and lead management often come from CRM or marketing automation. MARINI synchronizes bidirectionally and respects the responsibilities of each system.
weclapp and SAP Business One address a similar market segment. weclapp as a pure cloud solution is quicker to deploy, while SAP B1 offers more functional depth for more complex requirements. MARINI can seamlessly integrate both systems, regardless of your ERP choice.
Via the MARINI Integration Platform, weclapp can be connected with virtually any system: CRM like HubSpot or Salesforce, marketing automation like Evalanche or Inxmail, e-commerce like Shopware or Magento, and more. Bidirectional and in real time. Custom systems can also be connected via individual adapters.
MARINI detects duplicates based on configurable matching rules: email, customer number, domain, or custom fields. You define which system is leading in case of conflicts. Duplicates are merged or marked as exceptions, depending on your configuration.
Yes, MARINI supports multi-channel scenarios. Multiple shops, marketplaces, or direct sales converge in weclapp. Inventory levels and prices remain synchronized. You define per channel which articles are available and how orders are mapped in weclapp.


Data is only the gold of the digital age when it is integrated and consistently translated into decisions. That is exactly what MARINI stands for: we connect data sources, make data actionable, and enable purpose-driven, model-based analytics—fully aligned with the principles of Robotic Selling.
