Whether you’re building your first embedded finance product, expanding into new markets, or modernising existing financial capabilities, we provide the architecture, engineering, and governance needed to integrate BaaS platforms securely, efficiently, and at scale.
We help you unlock the power of BaaS — with faster speed to market, lower operational burden, and full regulatory alignment.
Understanding BaaS Platform Integration
BaaS platforms act as the backbone for embedded finance, offering ready-made financial capabilities delivered through APIs. They enable organisations to issue cards, open accounts, move money, or run identity checks without building regulated infrastructure themselves. But unlocking their full potential requires deep, reliable integration into customer journeys, back-office systems, risk processes, and operational workflows.
Integrating with a BaaS platform introduces unique challenges. APIs must be consumed consistently. Data must be synchronised in real time. Customer journeys must remain seamless and secure. And every flow — from onboarding to transactions — must meet regulatory expectations, whether PSD2, FCA/PRA guidance, AML/KYC rules, DORA, or internal governance structures.
At 6B, we specialise in architecting and delivering robust integrations across BaaS providers — supporting everything from account creation and card issuance to payments, identity, risk, and reporting. Our work ensures your BaaS integration is stable, compliant, and able to scale with your ambitions.
Our BaaS Platform Integration Approach
Our approach begins with a structured assessment of your target BaaS provider’s API capabilities, the financial products you intend to offer, and the surrounding systems that must interact with the platform. We map end-to-end journeys — onboarding, payments, card issuance, verification, support, and servicing — to understand data flows, orchestration needs, and regulatory considerations.
Based on this foundation, we design integration patterns that align with your architecture, whether you need direct API consumption, orchestration layers, event-driven flows, or hybrid patterns combining legacy and modern systems. We implement secure, scalable connectivity for account management, payments, card programmes, KYC/AML checks, transaction categorisation, treasury operations, and reporting functions.
Throughout delivery, we embed security, auditability, and operational readiness — ensuring API calls, webhooks, events, and data flows are traceable, resilient, and fully aligned with your compliance and risk controls. We support integration with CRM platforms, data warehouses, fraud and AML engines, customer support systems, and financial reporting tools. Extensive functional, performance, and failover testing ensures your embedded financial capabilities are production-ready and robust under real-world demand.

Readiness checklist for Banking-as-a-Service (BaaS) Platform Integration
- Identify the target BaaS provider and products required (accounts, payments, cards, KYC/AML, lending, data services)
- Provide architecture diagrams, data models, and existing system integrations
- Define regulatory considerations including PSD2, FCA/PRA, AML/KYC, DORA, and internal governance
- Confirm customer journeys requiring BaaS orchestration (onboarding, servicing, payments, card issuance)
- Document non-functional requirements: performance, latency, uptime, resilience, and auditability
- Finalise webhook/event handling requirements, security standards (OAuth, OIDC, MTLS), and API access
- Provide operational workflows for reconciliation, risk, fraud, and dispute handling
- Agree SLAs, monitoring, observability, and logging expectations
