2 Best APIs for Fraud Prevention in Nigeria

Veriff is an AI-powered identity verification platform that analyzes over 1,000 signals per verification session to deliver 99.6% automated decision accuracy. Founded in 2015 in Tallinn, Estonia, Veriff serves clients in over 230 countries and territories, including financial institutions, fintech companies, crypto exchanges, insurance providers, and digital marketplaces. The company processes hundreds of millions of verifications annually and is trusted by organizations including Bolt, Monzo, Skyscanner, and Gett. ## What the API Does Veriff's platform combines document verification, biometric face matching, liveness detection, and AML screening in a single developer-friendly API. The verification engine analyzes the submitted ID document (passport, national ID, driver's license) across authenticity signals including security feature checks, MRZ data validation, NFC chip reading, font consistency, microprint analysis, and document template cross-referencing. Simultaneously, a biometric face match compares the selfie captured during the session against the document photo, and liveness detection confirms the person is physically present rather than presenting a static photo or video replay. For Nigerian users, Veriff supports the full range of commonly accepted government IDs: international passports (Nigerian e-passports with NFC), National Identity Management Commission NIN slips, Independent National Electoral Commission voter cards, and Federal Road Safety Corps driver's licenses. ## How Developers Use It Developers integrate Veriff via REST API and pre-built SDKs (Web, iOS, Android, and React Native). The standard flow is: 1. Create a verification session on your backend using `POST /v1/sessions` — this returns a session URL and token. 2. Redirect or embed the Veriff session flow using the Veriff Web SDK or deep-link on mobile. 3. The end user is guided through document capture and selfie/liveness steps within the Veriff-hosted UI. 4. Veriff processes the session and delivers results via webhook to your configured endpoint. Results include an overall decision (approved/declined/resubmission_requested), individual check results (document authenticity, face match score, liveness pass/fail), and extracted data fields (full name, date of birth, document number, expiry date, address if present). Veriff also provides a verification URL-only integration for even simpler embedding — generate a session URL and open it in a browser window; no SDK required. ## Pricing & Fees Veriff offers transparent self-serve pricing, which sets it apart from many enterprise-only KYC vendors. Plans include: - **Essential**: $49/month — basic document + face verification - **Plus**: $99/month — adds database checks and enhanced fraud signals - **Premium**: $209/month — full feature access including AML screening add-on Per-verification costs apply above plan-included volumes, with exact per-check rates determined at signup. Enterprise plans with custom pricing and volume discounts are available for high-volume clients. A sandbox environment is available immediately upon signup for integration development. ## Authentication Veriff uses an API key + shared secret authentication model. Your API public key is included in request headers (`X-AUTH-CLIENT: your_api_key`), and a session-specific signature is generated using HMAC-SHA256 with your shared secret. For incoming webhooks, Veriff signs the payload using HMAC-SHA256, and the signature is passed in the `X-HMAC-SIGNATURE` header. Developers must verify this signature on every received webhook before processing the decision — accepting unverified webhook payloads in production is a critical security vulnerability. ## Rate Limits Rate limits vary by plan. Self-serve plans have monthly verification caps; exceeding these triggers overage billing rather than hard blocks. Enterprise plans have customized throughput limits based on expected session volume. Contact Veriff support for specific rate limit details on your plan. ## Compliance & Regulations Veriff holds ISO 27001 (information security management), SOC 2 Type II, and GDPR certifications. The platform is designed to support compliance with FATF recommendations, AMLD5/6 in Europe, and FinCEN guidelines in the US. For Nigerian deployments, Veriff's checks align with CBN KYC Tier 2/3 requirements (document + biometric verification), EFCC AML obligations, and NDPR data protection requirements. The AML screening add-on covers OFAC, UN, EU, and UK Treasury watchlists for PEP and sanctions screening. ## Challenges & Gotchas for Nigerian Developers 1. **Webhook signature verification is mandatory**: Skipping the X-HMAC-SIGNATURE check means your system could be manipulated by forged webhook payloads. Always implement this check before going live. 2. **HTTPS required**: The Veriff SDK will not load over HTTP. Your integration environment must be HTTPS-enabled. 3. **Session expiry**: Verification sessions expire after a configurable period (default 7 days). Build retry/re-invite flows for users who don't complete their verification promptly. 4. **Camera permission handling**: On Nigerian mobile devices running older Android versions, camera permission UX can vary. Test on low-end devices (Tecno, Itel, Infinix) which are common in Nigeria. 5. **No native BVN integration**: Veriff does not connect to the NIBSS BVN database. Pair with a Nigerian BVN API (Mono, Okra, Lendsqr) for BVN-based verification. 6. **NGN billing not supported**: Veriff charges in USD. Nigerian developers will need a USD-capable card or wire transfer. ## Company Background Veriff was founded in 2015 by Kaarel Kotkas in Tallinn, Estonia. The company has raised over $200 million in funding from investors including Tiger Global, IVP, and Alkeon Capital. Veriff employs over 1,000 people across Europe and the Americas and has won multiple awards for identity verification technology. In 2023–2024, the company invested heavily in AI-powered deepfake and document fraud detection, adding capabilities to counter sophisticated synthetic identity attacks. ## Frequently Asked Questions **Q: Can Nigerian developers sign up without contacting sales?** A: Yes. Veriff offers self-serve plans starting at $49/month with instant activation after signup.

Dojah Address Verification API is a specialized endpoint within the broader Dojah identity verification platform, enabling Nigerian businesses to validate customer addresses programmatically and in real time. Part of a comprehensive KYC ecosystem that also includes BVN verification, NIN lookup, and document checks, the Address Verification API allows fintechs, lenders, e-commerce platforms, and logistics companies to confirm that submitted addresses are legitimate Nigerian locations — reducing fraud, improving delivery success rates, and maintaining regulatory compliance. Dojah was founded to make identity verification accessible and affordable for African businesses. The address verification product directly addresses a challenge unique to the Nigerian market: informal and inconsistent address formats. Unlike countries with standardized postal systems, Nigerian addresses often rely on local landmarks, neighborhood names, and abbreviated LGA references that vary by city and speaker. Dojah's API normalizes and validates these inputs against reference databases, providing a structured verification result. **How Address Verification Works** The API accepts address details including street, LGA, state, and postal code. It cross-references this against verified address databases and geospatial records to return a confidence score and structured verification result indicating whether the address exists and can be matched to a known location. For enhanced verification, Dojah can also cross-reference the address against identity records tied to BVN or NIN, confirming that the person claiming to live at an address actually has records linking them to that location. The API returns standardized responses in JSON format, making it straightforward to integrate into onboarding flows. A pass result indicates the address is verifiable; a fail or low-confidence result triggers manual review or additional verification steps. **KYC Compliance for Nigerian Fintechs** The Central Bank of Nigeria's KYC guidelines require financial institutions to verify customer addresses as part of customer due diligence. This applies to digital banks, lending platforms, cryptocurrency exchanges, investment apps, and payment processors operating under CBN regulation. Failing to adequately verify addresses exposes businesses to regulatory penalties and increases fraud exposure. Dojah's Address Verification API provides an automated, auditable way to fulfill this requirement. Each verification creates a timestamped record that can be stored and presented to regulators during audits. By automating what would otherwise be a manual document-review process, companies can onboard hundreds of customers per day without proportionally scaling their compliance team. **Fraud Prevention in E-Commerce and Lending** Nigerian online merchants face significant losses from card-not-present fraud and account takeover attempts. One common fraud signal is a mismatch between the billing address on file and the delivery address submitted at checkout. By verifying both addresses through Dojah's API, merchants can flag suspicious orders before fulfillment. For digital lenders using BNPL models or personal loan products, address verification is a key signal in credit risk assessment. A borrower who cannot verify their stated home address represents higher default risk. Automating this check at the application stage reduces manual underwriting time and improves the quality of the loan book. **Logistics and Last-Mile Delivery** Failed deliveries cost Nigerian logistics companies money in wasted fuel, courier time, and customer service overhead. A significant portion of failed deliveries result from incorrect or incomplete addresses submitted at checkout. The Dojah Address Verification API can be integrated at the point of checkout or dispatch to validate that a delivery address corresponds to a real, locatable Nigerian location before a courier is dispatched. This pre-dispatch validation reduces failed first-attempt deliveries, improves courier efficiency, and lowers the rate of customer refund requests. For high-volume logistics operations managing hundreds or thousands of daily deliveries across Lagos, Abuja, and other Nigerian cities, even a small improvement in first-attempt delivery success translates directly to significant cost savings. **Sandbox for Safe Testing** Dojah provides a sandbox environment that mirrors the production API with test data, allowing developers to build and test address verification flows without consuming paid API credits or exposing real customer data during development. The sandbox uses realistic Nigerian address formats and returns both pass and fail scenarios, enabling thorough testing of application error handling and edge cases. **Integration with the Dojah Ecosystem** One of the most powerful aspects of using Dojah Address Verification is its native integration with the wider Dojah platform. A business can combine address verification with BVN verification, NIN lookup, facial recognition, and document scanning in a single API relationship, simplifying vendor management and potentially reducing per-verification costs through bundled pricing. This makes Dojah an attractive one-stop KYC solution for Nigerian fintechs and regulated businesses. Authentication uses standard API Key headers, and the RESTful endpoints follow predictable patterns documented in the Dojah developer portal. Onboarding is fast — a developer can obtain API credentials, integrate the endpoint, and run their first verification within a day. For Nigerian businesses navigating the dual challenge of regulatory compliance and fraud prevention, Dojah Address Verification API is a targeted, effective tool that automates one of the most operationally complex parts of customer onboarding.
