API Development
RESTGraphQLEndpoints
REST APIs, GraphQL interfaces and custom endpoints for platforms, digital products, internal tools or partner systems that need clean access to data and functionality.
API Integration Agency Berlin
APIs & Integrations
From Berlin.
We develop APIs, webhooks and integrations that connect systems intelligently, from CRM, ERP, shop and website to payment, internal tools and third-party services. With a clear view of data flows, process logic and what needs to work reliably in daily operation.
APIs & Integration
When Systems Need to Speak to Each Other.
Most companies work with dozens of digital systems side by side: CRM, shop, website, accounting, marketing, analytics and internal tools. As long as they do not communicate cleanly, teams work around gaps manually, data is maintained twice and important information gets lost in daily operation. Good integrations solve exactly that.
We develop APIs, integrations and data flows with the ambition to understand the whole system landscape, not just the two endpoints of a connection. Which data needs to move where, which rules and status logic apply and who depends on the result: this picture determines whether an integration works reliably in practice.
Typical Projects
What We Develop APIs and Integrations For.
We connect systems, develop APIs and build data flows with a clear view of the processes and teams that rely on them.
System Integration
CRMERPSync
Connections between CRM, ERP, shop, website, accounting, support and internal applications that keep data and status in sync reliably.
Data Pipelines and Feeds
PipelinesFeedsData Flow
Structured data flows for product data, market information, financial data or operational data that need to come together from different sources and be prepared for use.
Webhook and Event Systems
WebhooksEventsTriggers
Event-driven integrations that trigger processes in other systems when orders, status changes, form submissions or system events happen.
Third-Party Integrations
PaymentShippingMarketing
Integration of payment, shipping, marketing, analytics, communication and other services into existing systems and platforms.
Data Import and Synchronization
ImportExportSync
Scheduled imports, exports and sync processes for product data, inventory, contacts, transactions or reports between internal and external systems.
The Right Foundation
When Systems Need to Work Together.
APIs and integrations become the right step when data sits in silos, processes get stuck at system boundaries or manual work slows down growth.
Services
From Analysis to Operation.
We handle all phases of an integration project, from system analysis and API design to connection, data logic and ongoing monitoring.
The Right Partner
Why BxW.
Good integrations emerge when the systems on both sides are understood. We work with websites, shops, data platforms, AI and infrastructure ourselves, and bring that understanding into every integration.
The Whole Landscape in View
We do not think in isolated connections, but in system landscapes. Data flows, dependencies and process logic are considered together before the first line of code is written.
Web, Data, AI and Infrastructure in One Team
We integrate systems we know from our own work: CRM, ERP, shops, CMS, databases, AI services and cloud infrastructure. This reduces ramp-up time and prevents wrong assumptions.
Processes Matter, Not Only Data Transfer
An integration is not just a data channel. We look at the rules, status logic, validation and sequence behind the data so the integration actually reduces work.
Stability for Daily Operation
Error handling, retry logic, logging and monitoring are not extras for us. They are part of every integration. Interfaces show their value when they run reliably under load and in edge cases.
Further Development With Overview
When new systems, requirements or data sources are added, existing integrations remain understandable and extendable. We document interfaces so they can be maintained long term.
Existing Integrations
Do Your Integrations Need an Upgrade?
We take over existing integrations and improve stability, error handling, performance and documentation, whether the next step is modernization, extension or a move to new systems.

Key Questions
Before the Integration Project.
What does BxW do as an API integration agency?
BxW develops APIs, webhooks and system integrations for companies whose digital systems need to work together cleanly. We connect CRM, ERP, shops, websites, accounting, marketing, payment and internal tools so data flows reliably and processes interact automatically.
Which systems can BxW integrate?
We integrate common business systems, shops, websites, databases, automation tools and internal applications. We know tools such as Salesforce, HubSpot, SAP, Shopify, WooCommerce, Stripe, Supabase and n8n from practice. The tool name matters less than whether interfaces, permissions, data models and process logic can be represented cleanly.
Does BxW develop custom APIs?
We design and develop REST APIs, GraphQL interfaces and custom endpoints for platforms, digital products, partner systems or internal applications, with clean documentation, authentication and access control.
How does an integration project with BxW work?
We start by analyzing the existing system landscape, data flows and processes that cross system boundaries. From this, we create an integration plan with clear priorities. Implementation, testing and monitoring follow step by step, so each connection is checked before production use.
What is the difference between an API and an interface?
An interface is the general handover point between two systems. An API is a concrete technical implementation that standardizes this handover point and makes it accessible to software. In practice, we use both terms depending on whether the focus is the business connection or the technical implementation.
Can BxW improve existing integrations?
Existing integrations can be improved when data flows are unstable, error handling is missing, systems change or new requirements are added. At the beginning, we look closely at architecture, data quality and operational stability of the current connections.
Which technologies does BxW use for APIs and integrations?
We work with REST, GraphQL, webhooks, n8n, Node.js, Python, PostgreSQL, Supabase, Docker and APIs of common business systems. The technology choice follows requirements around performance, security and maintainability, not trends.
How are integrations monitored in operation?
We secure integrations with logging, error handling, retry logic, alerts and systematic monitoring. Failed transfers, outages and performance issues are detected before they interrupt operational processes.
What affects the scope of API development or system integration?
Scope comes from the number of systems, quality of interfaces, data logic, security requirements, error handling and operations afterwards. A simple connection is a different project from an integration that has to carry status logic, data validation, monitoring and several teams reliably. We clarify scope, risks and priorities first.
Does BxW support integrations long term?
If needed, we take care of monitoring, error handling, adjustments and new integrations after launch. This keeps interfaces stable when systems are updated, processes change or new tools are introduced.
Discuss an Integration Project.
Whether API development, system integration, data pipeline or modernization of existing interfaces: the best starting point is a conversation about systems, data flows and the goal of the connection.
