Mambu Integration

6B are trusted integration specialists with hands-on experience connecting digital financial products to Mambu’s composable banking architecture. We support full lifecycle integration using Mambu’s REST APIs, event streams, and microservices-friendly patterns. From requirements mapping and solution design through to development, testing, deployment, and ongoing optimisation, we enable reliable, compliant, and future-proof integrations that unlock Mambu’s full potential.

As a dedicated digital engineering partner, our mission is to support financial innovation by enabling secure, real-time data exchange between your product ecosystem and Mambu’s core banking capabilities.

Understanding Mambu

Mambu is a cloud-native, SaaS core banking platform designed around a flexible, composable architecture. It enables financial institutions to create and scale lending, deposit, payments, and digital banking products using a modern, API-first approach. Mambu separates product engines, workflows, and data structures into modular components, allowing rapid configuration without the limitations of monolithic legacy cores.

Mambu’s integration model is built on RESTful APIs, asynchronous event notifications, and microservices-based extensibility. This supports low-latency data exchange across customer onboarding, loan management, accounts, transactions, KYC/AML, and payment operations. With role-based access control, audit logging, and ISO-aligned controls built in, Mambu provides a secure foundation for digital financial services.

The platform’s composable design allows institutions to integrate best-of-breed providers across KYC/AML, credit scoring, payment gateways, CRM, and fraud detection — enabling a full ecosystem approach to product innovation. Sandbox environments and rich developer documentation support fast build cycles and consistent implementation.

Our Mambu Integration Process

At 6B, we follow a structured, collaborative integration approach designed to align with your functional, technical, and regulatory requirements. We begin with a discovery phase where we map your use cases — onboarding workflows, lending automation, deposits, payments, customer data synchronisation, or operational reporting — to the appropriate Mambu APIs, events, and components.

Our architects design a secure, scalable integration architecture using REST APIs, event-driven messaging, OAuth 2.0 authentication, and microservices patterns. We consider data mapping, rate limits, product configuration, idempotency, error handling, and compliance requirements such as FCA, UK GDPR, and PSD2 where applicable.

During development, we leverage 6B’s reusable frameworks for integration orchestration, API management, and event processing. Using Mambu’s sandbox, we validate all interactions for functional accuracy, security, and performance. This includes customer and account creation flows, transaction posting, loan lifecycle events, scheduled repayments, and custom product workflows.

Once testing is complete, we manage production onboarding, configure API access and credentials, and support the go-live process. After deployment, we provide continuous monitoring, maintenance, and enhancements to ensure long-term reliability as your product offering or Mambu’s platform evolves.

Benefits of Mambu Integration

Mambu Integration FAQs

What types of systems can be integrated with Mambu?

Mambu’s API-first architecture allows integration with a wide range of financial services platforms, including KYC/AML providers, credit bureaus, payment gateways, card processors, CRM systems, loan origination tools, analytics platforms, and customer-facing mobile or web applications. Its REST APIs and event streams support both synchronous and asynchronous data exchange.

How long does a typical Mambu integration project take?

Timeframes vary depending on project scope, regulatory requirements, and the number of connected systems. A simple integration—such as account creation or basic transaction workflows—may take a few weeks, whereas full-lifecycle lending or multi-system orchestration can take several months. We outline realistic delivery timelines during discovery.

Is Mambu integration secure and compliant with financial regulations?

Yes. Mambu is aligned with leading security and compliance frameworks including ISO 27001, GDPR, and regional financial regulations. Our integration solutions incorporate secure authentication (OAuth 2.0), encrypted communication, audit logging, role-based access, and compliance-by-design principles to meet FCA and regulatory expectations.

Can Mambu support real-time processing for loans, deposits, and payments?

Absolutely. Mambu’s real-time APIs and event-driven architecture make it well-suited for instant account creation, loan updates, scheduled repayments, transaction posting, and payment notifications. Integrations can operate in real-time, batch mode, or hybrid models depending on your business requirements.

Do we need an in-house engineering team to maintain the integration?

No. 6B provides ongoing support, monitoring, optimisation, and incident response to ensure your integration remains stable and up to date as Mambu evolves. However, if you have internal teams, we can work collaboratively or hand over technical documentation and training.

Can Mambu integrations be customised to match unique workflows or product structures?

Yes. Mambu’s composable architecture is designed for flexibility. We configure custom product rules, repayment schedules, fee structures, onboarding steps, and operational workflows, ensuring the integration aligns with your business model and customer experience.

What environments are available for testing Mambu integrations?

Mambu provides sandbox and pre-production environments that mirror production behaviour. These environments support end-to-end testing of API calls, event flows, authentication, and performance before launch. We use these environments extensively to ensure reliability and compliance.

Can Mambu integrate with legacy systems or on-premise infrastructure?

Yes. Using middleware, microservices, and secure API gateways, we can bridge modern Mambu APIs with older platforms that may rely on outdated data models or batch processes. We design hybrid architectures that allow organisations to modernise progressively without disrupting existing operations.
