Embedded finance infrastructure: what businesses actually need to build financial products

Embedded finance allows businesses to integrate financial services directly into their own products. A marketplace can give sellers account details to collect funds. A fintech can enable customers to hold multiple currencies. A platform can manage payments and payouts without sending users to a separate financial provider.

The experience may look simple to the customer. The infrastructure behind it is not.

Accounts, payment rails, FX, regulatory requirements and technology all need to work together. As businesses expand, the challenge is increasingly not how to add another financial feature, but how to build an infrastructure layer that can support multiple products, markets and customer needs without adding unnecessary operational complexity.

What is embedded finance?

Embedded finance is the integration of financial services directly into a company’s product or platform, with the underlying financial infrastructure operating behind the user interface.

For the customer, financial services become part of the platform they already use. They do not necessarily need to move between different providers to complete a financial task. The business retains control of the customer journey, allowing the experience to remain consistent with its own brand and product.

Consider a marketplace that needs to collect funds from buyers, allocate them to individual sellers, convert currencies and make payouts across different markets. Those services may ultimately rely on regulated financial institutions and payment networks, but they can be integrated into the marketplace itself. Sellers continue to interact with the platform they know, rather than the different providers powering each transaction behind the scenes.

A trading platform could similarly provide customers with named account details for deposits and automatically reconcile incoming funds. A digital asset business might connect fiat accounts, payment rails and blockchain infrastructure so customers can move between traditional currencies and digital assets through one experience.

This separation between the customer experience and the infrastructure underneath it is central to embedded finance. The business controls how the service is presented and experienced, while infrastructure providers supply the technology, connectivity and regulated capabilities required to deliver it.

How has embedded finance infrastructure evolved?

For many businesses, financial infrastructure has evolved incrementally.
A company may have started with a single payment provider, then added new providers as it expanded into different markets, currencies and payment methods. Over time, what began as a relatively simple payment experience can become a network of banking partners, payment providers, FX providers and other financial services.

Each integration may solve a specific requirement, but the cumulative result can be a fragmented infrastructure stack that the business has to integrate, reconcile and maintain.

Financial infrastructure platforms offer a different model. Rather than connecting each capability individually, businesses can access multiple financial services through a single infrastructure layer, with APIs providing the technical connection between that infrastructure and the business’s own product.

OpenPayd’s model, for example, brings accounts, Virtual IBANs (vIBANs), payments, FX and digital asset infrastructure together through one API, aggregating connectivity to the underlying financial network. The goal isn’t to consolidate for the sake of consolidation. It’s to reduce unnecessary integrations and operational complexity while maintaining the coverage and resilience the business requires.

How do APIs enable embedded finance?

APIs are a core part of modern embedded finance infrastructure. They provide the technical connection between a business’s product and the financial services operating behind it, allowing financial capabilities to be integrated directly into the customer experience.

What is an API?

An API, or Application Programming Interface, allows different technology systems to communicate and exchange instructions or information.
In practice, this means a business can integrate financial processes directly into its own platform. When a customer opens an account, receives individual account details, checks a balance, converts currencies or initiates a payment, the platform can use an API to send the relevant request to its financial infrastructure provider and receive a response.

The underlying service may be provided by another financial institution, but the customer can complete the action without leaving the business’s own platform.

This is one of the foundations of embedded finance: the customer-facing product and the infrastructure powering it can be separate, while APIs connect the two.

What is API documentation and why does it matter?

API documentation is the technical reference that shows developers how an API works and how to integrate with it.
It should set out the functionality available, authentication requirements, API requests or endpoints, required data, expected responses and potential errors. This allows technical teams to assess how the financial infrastructure will connect with their existing technology before implementation begins.

A provider may offer the right capabilities commercially, but the business also needs to understand how those capabilities can be integrated, tested and operated.

A sandbox supports this assessment by giving developers a test environment in which they can build and test API interactions before connecting to the live production environment. OpenPayd provides API documentation and sandbox access so developers can explore its infrastructure and test workflows before going live.

What infrastructure do businesses need to offer embedded financial services?

The exact requirements depend on the product, markets and customers being served. However, embedded finance infrastructure can combine several core capabilities.

Account infrastructure. Products that allow customers to receive, hold or manage money need appropriate account structures. Virtual accounts and Virtual IBANs can also provide individual account details that help businesses identify transactions and automate reconciliation.

Payment infrastructure. Businesses need connectivity to the payment rails that move money into and out of their products. An international proposition may require multiple domestic and cross-border payment networks across different currencies.

FX and treasury infrastructure. Products operating across currencies may need foreign exchange alongside the ability to manage balances and liquidity.

Regulatory infrastructure. Regulatory requirements depend on the financial activities being performed and the jurisdictions involved. In the UK, for example, the FCA identifies operating payment accounts, executing payment transactions and money remittance among the activities covered by payment services regulation. Businesses therefore need to establish which entities perform regulated activities and where the associated responsibilities sit.

The combination required will differ by business. What matters is whether the infrastructure can support the financial product as a whole rather than simply an individual feature.

What should businesses look for in an embedded finance infrastructure provider?

Which financial services can the embedded finance provider support?

Consider the wider product roadmap, not only the first capability being launched. Access to accounts, Virtual IBANs, payments, FX and other services through the same infrastructure can reduce the need for additional integrations as the proposition develops.

Which countries, currencies and payment rails does the embedded finance infrastructure support?

International businesses should assess whether the provider supports the currencies, account structures, payment rails and jurisdictions required today and in planned markets.

Can one financial infrastructure integration replace multiple provider integrations?

Every additional provider can introduce another integration, contract, reconciliation process and operational relationship. Consolidating capabilities can reduce this complexity, while businesses should also consider resilience and concentration risk within their wider architecture.

Can the embedded finance infrastructure support higher transaction volumes and international expansion?

Requirements change as volumes grow and businesses enter new markets. Assess whether the provider’s technical infrastructure, currency coverage, payment rails and financial network can support both current requirements and planned expansion.

How comprehensive is the embedded finance provider’s API documentation?

Technical teams should assess API endpoints, authentication, workflows, responses, error handling and sandbox access. These provide an early indication of the functionality available and the integration work required.

What financial infrastructure sits behind the API?

An API is the interface, not the entire infrastructure. Businesses should understand the licences, banking relationships, payment connectivity, controls and operational processes that ultimately enable money to move.

What is the difference between embedded finance and Banking-as-a-Service (BaaS)?

Embedded finance and Banking-as-a-Service are closely related, but they describe different parts of the model.
Embedded finance describes the proposition: financial services integrated into another company’s product and customer experience.
Banking-as-a-Service describes an infrastructure model: banking or financial capabilities provided to another business through technology such as APIs.

BaaS can therefore enable embedded finance, but the terms are not interchangeable. For businesses evaluating infrastructure, the more important questions are what capabilities are provided, which regulated entities sit behind them and how the infrastructure fits into the intended product.

Why does financial infrastructure matter as embedded finance scales?

Launching the first financial feature is only part of the challenge.
As a business expands, it may need new currencies, additional payment rails, different account structures or access to new markets. Building each capability through a separate provider can increase the technology, operational and administrative burden associated with running the product.

An infrastructure partner can instead consolidate multiple financial capabilities and underlying connections into a single relationship.
OpenPayd’s rail-agnostic infrastructure brings accounts, payments, FX and digital asset capabilities together through a single API. The model is designed to give businesses access to a broader financial network without requiring a separate integration for every underlying capability.

For businesses building embedded financial products, infrastructure is therefore not simply a technical consideration. It influences how efficiently the business can operate, how easily it can introduce new capabilities and whether the architecture can support the product as its requirements grow.

Embedded finance infrastructure: frequently asked questions

What is embedded finance infrastructure?

Embedded finance infrastructure is the technology, financial connectivity and regulated services that enable a business to integrate financial capabilities into its own product. Depending on the use case, this can include APIs, accounts, Virtual IBANs, payment rails, FX and regulatory infrastructure.

What is an embedded finance API?

An embedded finance API is the technical interface connecting a business’s product with its financial infrastructure. It can enable actions such as creating accounts, retrieving balances, executing FX conversions and initiating payments directly from the business’s own platform.

What are the benefits of using a financial infrastructure partner for embedded finance?

A financial infrastructure partner can reduce the operational complexity of managing multiple financial providers independently.
Instead of maintaining separate integrations, contracts and day-to-day relationships for different capabilities, a business can access multiple financial services through one provider, creating a central point of contact for a wider range of infrastructure and operational requirements.

Consolidation can reduce the internal time spent administering providers, maintaining integrations and coordinating operational processes. This allows product, technology and operations teams to focus more resources on the customer proposition rather than managing the infrastructure underneath it.

Does a business need a financial services licence to offer embedded finance?

It depends on the activities being performed, the business model and the jurisdictions involved.
Some businesses use regulated partners to provide underlying financial services, while others are themselves regulated and hold permissions appropriate to their activities, such as an Electronic Money Institution authorisation or a Money Services Business registration.

The key consideration is which entity performs each regulated activity and whether it has the appropriate permissions to do so.

What is the difference between embedded finance and embedded payments?

Embedded payments refer specifically to payment functionality integrated into another product. Embedded finance is broader and can include payments alongside capabilities such as accounts, FX and other financial services.
