Sumsub + Supabase API Integration

@AwaisChaudhry

Hello, I will wire Sumsub’s Identity Verification into your Supabase stack so new users move from sign-up to verified smoothly. I’ll create secure server-side bridge code in TypeScript/Node that: creates a user in Supabase Auth, requests a Sumsub applicant token, and drives the verification flow via Sumsub APIs. I’ll surface results in real-time through PostgreSQL streaming and Supabase listeners, update the DB with status changes, and push updates to the UI without a page refresh. I’ll implement robust error handling, retries, and store webhook events in the same schema for easy auditing. Deliverables include server code that securely handles secrets, DB migrations for any new tables/columns, sample frontend calls showing auth and live status updates, and a concise README with environment variables, testing steps, and deployment guidance. I’ll follow best practices for secrets, logging, and production readiness, with clean, commented code and documentation. What is your preferred environment for testing webhooks and which Sumsub regions/settings are mandatory for your users? Best regards,

Hi there, I have experience wiring Sumsub’s Identity Verification (KYC) into modern stacks and can integrate it seamlessly with your Supabase (Auth + Postgres + real‑time channels) setup. The flow will ensure new users move directly from sign‑up to verified status inside your product. Approach: - Supabase Auth creates a user record → request Sumsub applicant token immediately. - Integrate Sumsub SDK/REST for document capture + video selfie inside the app. - Verification results flow back via webhooks into Supabase, updating Postgres and pushing status changes through real‑time subscriptions. - Errors, retries, and webhook events logged in the same schema for auditing. Deliverables: - Secure server‑side TypeScript/Node code bridging Supabase + Sumsub. - Database migrations/SQL for new tables/columns. - Sample front‑end calls showing auth, verification flow, and live status updates. - README with environment variables, local testing, and deployment steps. Experience: I’ve implemented production‑ready KYC flows with Sumsub, ensuring clean code, best practices for secrets management, and smooth real‑time updates. Regards, Asif Ali Zaman

Hello! I can wire Sumsub KYC cleanly into your Supabase stack so new users move from sign-up to verified status with real-time updates and full audit traceability. Proposed Architecture: Core Engine • Supabase Auth trigger (Edge Function) creates Sumsub applicant + returns applicantToken • Secure Node/TypeScript service for Sumsub REST + webhook validation • Postgres KYC schema (applicants, verification_status, webhook_events, retries) • Supabase Realtime subscriptions to push status changes instantly Flow • User signs up → DB record created • Edge Function requests Sumsub applicant token (server-side, signed) • Frontend loads Sumsub SDK for doc + selfie capture • Sumsub webhook hits secure endpoint → signature verified • Status persisted in Postgres → Realtime channel updates UI live Reliability & Audit • Idempotent webhook handler • Error + retry logging table • Enum-based KYC states (pending, review, approved, rejected) • Full event history for compliance review Deliverables • Server-side bridge (Sumsub ↔ Supabase) • SQL migrations • Sample frontend flow (auth + live status) • README with env vars, local setup, deploy guide All secrets managed via Supabase project env + server-only execution. Production-ready and audit-safe. Let’s align on hosting (Supabase Edge vs separate Node service) and environment strategy so we can implement cleanly. Best regards, Jasmin

Hi there, I’m excited about the opportunity to assist with the Sumsub and Supabase API integration. Successfully bridging these two systems will enable a seamless experience for your users, and I have extensive experience in similar projects. **1. Relevant Experience:** I have successfully integrated various APIs in the past, notably in identity verification and KYC flows, ensuring secure and efficient data transfers. My expertise with Supabase already includes managing authentication and real-time subscriptions effectively. **2. Solution Steps:** - Implement Supabase Authentication to trigger a Sumsub applicant token request seamlessly. - Leverage Sumsub’s SDK for document verification, ensuring the user experience remains fluid within the app. - Create real-time subscriptions for verification results to update the UI instantly, enhancing user experience. - Develop a comprehensive error handling and logging system using Postgres for clear auditing. Everything will be methodically organized, well-commented, and ready for production when merged. I understand your Figma designs will guide the UI iterations, which aligns perfectly with my prototyping skills. What specific area would you like to discuss further?

@rajubhalani

For seamlessly integrating Sumsub's Identity Verification and KYC flow into your Supabase stack, I propose initially reviewing the current Supabase setup to understand the existing logic flow. Following this, I would suggest outlining a clear plan to connect Supabase Authentication with Sumsub's applicant token generation process, ensuring a smooth transition for new users from sign-up to verified status within the product. So I believe that by bridging the gap between Supabase and Sumsub APIs, we can achieve a streamlined process where user data is securely verified in real-time, updating the database and front-end interface seamlessly without the need for manual refreshes. By the way, could you provide insights into the expected timeline for this integration process? Understanding the urgency and priorities will help in planning the development and deployment phases effectively.

Hello, I’m excited about the opportunity to contribute to your project. With my experience integrating Supabase (Auth + Postgres + Realtime) with third-party KYC providers, I can wire Sumsub end-to-end so sign-up creates the user record, issues an applicant/access token server-side, launches the SDK verification flow, and streams status changes back to the product instantly via realtime subscriptions. I’ll tailor the backend bridge in TypeScript/Node with secure secrets handling, webhook verification, robust error/retry logging, and a clean Postgres schema for applicants, verification events, and audit trails, so everything is traceable in one place. You can expect clear communication, fast turnaround, and a production-ready deliverable including migrations, sample front-end calls for the live flow, and a short README for env vars, local testing, and deployment. Best regards, Juan

Hello I am a Full Stack Developer with hands-on experience integrating Sumsub's identity verification and KYC flows into Supabase-powered applications, and I am confident I can deliver the seamless sign-up-to-verified pipeline you need. I have built similar end-to-end verification systems where user creation, document capture, and real-time status updates all work together without manual intervention or page refreshes. The webhook handler will receive Sumsub's verification results, validate their signatures for security, and update your Postgres database immediately so that status changes propagate through Supabase's real-time subscriptions to the front end instantly. For the database layer, I will write clean migrations that extend your existing Postgres schema with the necessary tables and columns to store applicant IDs, verification statuses, document metadata, webhook event logs, and retry records. Everything will live within your current schema structure so that auditing verification history is straightforward with simple queries. The Sumsub SDK integration will guide users through document capture and video selfie steps directly inside the app, with proper error handling for rejected documents, expired sessions, and network failures. Every error and retry attempt will be logged in the database alongside webhook events so you have a complete audit trail for compliance purposes. Looking forward to your reply Regards.
