Enterprise identity proofing built and secured by one team

Integrating Onfido into financial products requires strict compliance, seamless user onboarding, and resilient backend pipelines. Whether building an MVP or upgrading an enterprise KYC flow, our engineering team implements end-to-end Onfido API integration across web and mobile platforms. We embed Onfido mobile SDKs for iOS, Android, and React Native, handle camera permissions, generate secure short-lived SDK tokens, and capture high-resolution document and biometric data. On the backend, we build signature-verified webhook listeners, automate applicant checks, and securely route verification results into your CRM or core banking system without exposing sensitive PII. AI coding tools accelerate test coverage and endpoint boilerplate, while our experienced engineers oversee data privacy, encryption, error recovery, and production releases.

AI-accelerated, expert-governed Onfido integration

How AI assists

  • Generates boilerplate API client code, payload serializers, and SDK wrapper methods across backend frameworks
  • Drafts comprehensive test suites for webhook ingestion, simulating check.completed and check.reopened payloads
  • Creates mock Onfido sandbox fixtures to test edge cases such as image glare, expired IDs, and unsupported documents
  • Scans integration logs and payload schemas to quickly pinpoint serialization mismatches and webhook parsing errors

What our experts own

  • Senior engineers design secure token exchanges and ensure applicant PII is never stored in unencrypted application logs
  • Security specialists verify HMAC webhook signatures, replay attack mitigations, and idempotent event processing
  • Mobile leads configure native camera permissions, capture UX fallbacks, and multi-platform SDK lifecycle stability
  • We oversee end-to-end sandbox-to-production cutover, rate-limit policies, and ongoing compliance monitoring

How an Onfido verification lifecycle executes

Illustrative verification pipeline; your regulatory rules and application architecture shape the exact flow.

  1. Applicant initiated

    Your backend registers an applicant record in Onfido via API and requests a short-lived SDK token.

  2. Client document capture

    The mobile or web SDK captures document photos and biometric video, validating image quality client-side.

    Checkpoint: Low-quality or blurry captures prompt immediate retry

  3. Check creation

    Your backend initiates an Onfido check specifying document and facial biometric fraud prevention reports.

  4. Webhook dispatch

    Onfido dispatches a check.completed webhook to your listener upon finishing algorithmic and manual verification.

  5. Signature verification and sync

    The endpoint authenticates HMAC signatures, checks idempotency keys, and updates your user database.

    Checkpoint: Invalid signatures or duplicate events are rejected

When something fails: Failed webhook deliveries or ambiguous verification reports trigger automated retries, followed by ops escalation alerts for manual compliance review.

Integration capabilities

What your Onfido integration can include

  • Onfido mobile SDK integration

    Embed native iOS, Android, Flutter, and React Native SDKs with optimized camera capture, glare detection, and fallback flows.

  • Custom Onfido document verification

    Configure supported government IDs, passports, and driving licenses with validation rules tailored to your regulatory jurisdictions.

  • Onfido biometric fraud prevention

    Implement selfie and liveness video checks to detect spoofing, deepfakes, and presentation attacks during user onboarding.

  • Idempotent webhook pipeline

    Build resilient backend listeners that verify webhook signatures, deduplicate retries, and process verification results once.

  • Backend applicant and check orchestration

    Automate applicant creation, secure SDK token issuance, check generation, and status syncing with your core database or CRM.

  • Audit trails and PII compliance

    Architect data retention and masking workflows to protect sensitive identity documents according to GDPR and regional privacy laws.

Engage our team for a dependable Onfido integration

  • Access and inputs

    Provide Onfido sandbox API credentials, repository access, target mobile SDK frameworks, and documentation on your KYC tiers and compliance obligations. Bring examples of required document types and user edge cases.

  • A realistic first scope

    Begin with a scoped assessment or a defined milestone: client-side SDK integration, applicant generation, and webhook reception. Advanced automated AML screening or multi-tier workflows can be delivered as sequential milestones.

  • Handover and maintenance

    We deliver tested source code, contract test suites, architecture documentation, and runbooks for webhook key rotation. Ongoing version updates, new SDK releases, and monitoring are supported through an agreed maintenance arrangement; Onfido API fees remain separate.

FAQ

Frequently Asked Questions

Why hire an Onfido integration expert instead of using generic boilerplate?

Identity verification handles sensitive PII, camera hardware, and financial regulations. An experienced Onfido identity verification developer ensures short-lived SDK tokens are generated server-side, webhooks are cryptographically validated against replay attacks, and document rejection states provide clear user feedback without breaking your onboarding conversion funnel.

How does the Onfido mobile SDK handle poor lighting or unreadable documents?

Onfido's mobile SDK provides real-time capture guidance, edge detection, and blur alerts directly in the camera view. We build user-facing fallback flows that guide applicants through retries, capture alternative document sides, and pass clear error signals so users can successfully complete document verification.

What happens if Onfido webhook delivery fails or times out?

We design webhook endpoints to be idempotent and asynchronous. The listener verifies the signature, records the event ID in a deduplication cache, acknowledges the request immediately, and enqueues processing. If delivery fails on Onfido's end, our scheduled reconciliation job polls check statuses to ensure no user verification is lost.
