A know your customer (KYC) or know your business (KYB) verification API can help financial services and payments companies mitigate operational limits, like:
- Fragmented systems. Multiple databases, online sources, and disconnected APIs increase integration complexity, friction points, and the risk of oversight and errors.
- Manual processing and saving information in a CRM repurposed as a data repository. But this is resource intensive and exposes firms to vulnerabilities, like data breaches, identity theft, and inefficient audit trails.
- Adopting a one-size-fits-all approach for different business entities and regions, leading to false positives and non-compliance.
When we launched our KYC and KYB solution for the financial services industry five years ago, we quickly realized efficient KYC didn't resolve the bigger problem—customer attrition throughout the entire onboarding flow.
So, we designed a customer onboarding solution that removes the friction from every step of the customer boarding process, enabling financial firms to grow their new reseller and merchant base worldwide more efficiently.
As verification experts, we'll share common challenges that make an API a viable solution, what to look for in an API, and how OnBoard helps payment companies and financial services access global KYC APIs through a single solution that resolves customer attrition for the whole registration process.
Key Takeaways
In this article, we'll cover:
- What's really blocking current KYC and KYB checks
- What to look for in a KYC API?
- Why choose OnBoard for a KYC API?
- How a multi-national firm processed 2,000+ KYC and KYB checks worldwide via OnBoard

What's Really Blocking Current KYC & KYB Checks?
The real challenges to KYC and KYB processes go beyond compliance. They're operational and consist of fragmented systems, manual checks and non-standardized approaches that increase risk and strain onboarding teams.
1. Juggling the Multiple Components Leading to Errors & Oversight
Verifying customer identities involves integrating five to ten different KYC APIs. This fragmentation increases the risk of errors and oversight, undermining compliance and fraud prevention.
KYC APIs range from document verification, address verification, and biometric verifications to anti-money laundering (AML) and politically exposed person (PEP) screenings. But KYB adds multiple steps to identify and verify:
- Business entity
- Ultimate Beneficial Ownership (UBO)
- Tax and VAT verification
- Legal status and licensin
For cross-border operations, this complexity increases to meet regional and local regulations.
The payments and financial services sectors also require deeper integration (often with existing legacy systems) and more maintenance due to frequent compliance changes and software updates, further complicating the onboarding process.
These more intricate integrations demand increased reliance on IT teams to connect disparate APIs. But customer verification teams wind up having to deal with fragmented workflows, with separate solutions for risk, fraud, and regulatory compliance.
2. Manually Verifying New Partners Compromises Audit Trail Quality
We see many businesses outsourcing their KYC and AML verifications because it's so resource intensive. Verification teams must gather customer data and documentation from disparate sources—including taking screen shots of IDs like driver's licenses and passports—analyze them manually, and store them compliantly to be audit ready.
This complexity increases when taking into account countries with regional variations (e.g. Brazil) or where there are limited readily available public databases.
Yet, these manual workflows increase the risk of false positives and human error, which can affect audit trails. Poor audit documentation can lead to increased regulator scrutiny, fines, and closure.
3. Applying One Model Introduces Risk & Aggravate Customers
Another common verification approach we've noticed is multi-industry firms and conglomerates using the same KYC model across all customer segments.
But a one-size-fits-all model doesn't take into account specific risk profiles and regulatory requirements. This results in either unnecessary friction for low-risk customers or insufficient checks for high-risk customers—both of which can lead to compliance failures and customer frustration.
Imagine a acquirer is onboarding two distinct types of merchants: a fashion wholesale marketplace (low risk) and an online gaming platform (high risk). Legally, the fashion marketplace requires basic KYC verifications, but the gambling line demands additional due diligence, including fraud, reputational and credit risk assessments.
To save time, the acquirer uses the same higher-risk workflow for both merchants. But subjecting new fashion partners to the high-intensity verifications that gambling clients go through, could lead to increased friction and drop-offs.
When these merchant types operate across multiple jurisdictions, compliance, fraud, and risk requirements become significantly more complex.
The best practice is to create different verification workflows for each risk profile. But this increases complexity for IT teams. Developers will need to ensure different KYC vendors and APIs work together seamlessly to avoid friction while meeting each profile's unique compliance requirements.
IT teams will also deal with increased workloads to ensure proper maintenance and updates of different KYC flows, inflating overhead costs.
What To Look For In An API For KYC Processes?
Choosing the right KYC API reduces integration complexity and speeds up deployment. It also helps eliminate risks such as data errors, audit gaps, and compliance failures while streamlining your onboarding flow.
- Consolidates services through a unified API. A single API can orhcestrate ultiple KYC workflows designed to cater to different product, risk profiles and jurisdiction. It delivers all essential checks such as AML, PEP screening, biometric verification, and identity authentication. This helps reduce technical complexity, integration costs, and the friction arising from incompatible systems.
- Supports international expansion with global KYC coverage. Global KYC requires an infinite number of screening and verification from multiple databases, to satisfy regulators on an international scale.
- Enables end-to-end automation—from automatic screen captures and analysis to decision making and storage—to reducing operational overheads while dynamically generating audit trails to support compliance processes and oversight.
- Offers flexible workflow customization. A robust solution allows for tailored workflows that can handle geographic nuances, varying risk profiles, and diverse business models, resulting in fewer false positives.
- Scales to meet future demand. Evaluating long-term scalability is essential when choosing a KYC solution. The API should support higher verification volumes and complexity as a customer base expands.
- Delivers a comprehensive onboarding experience. A unified platform that covers every stage of the customer onboarding journey, to create a seamless experience for both customers and internal stakeholders. Risk, fraud, sales and compliance teams can operate within a shared framework, without adding friction or compromising control.

Customizable KYC Flows for Global Onboarding
Applying the same KYC framework used for an initial product launch may be effective for a payment startup in its early stages. At low volumes, manual processes are manageable across compliance, risk and fraud teams.
But, as the business scales, a one-size-fits-all approach is unsustainable.
Verification volumes quickly outpace existing processes, while legal and compliance requirements grow more complex across jurisdictions. This increases the risk of false positives and regulatory non-compliance.
With OnBoard, financial services and payment firms can configure KYC workflows to meet evolving business needs dynamically.

Organizations can route any application, regardless of customer type or jurisdiction, through OnBoard's end-to-end platform and all via API. Our rules-based engine automatically assesses each one based on an organization's unique configurations.
