GoVisaX × Visa2Fly — Phase 14: Partner API & Developer Portal

Section 01

Executive Summary

Phase 14 completes the GoVisaX platform's public distribution layer — a fully documented, tier-gated Partner API that allows travel agencies, OTAs, and tech platforms to embed GoVisaX visa services into their own products, with zero Visa2Fly exposure at any integration point.

🌐

23 REST Endpoints

Covering visa applications, OTB, insurance, partner analytics, pricing, and utilities — all under /partner/v1 namespace with HMAC-signed JWT auth.

📦

4 SDK Languages

Node.js (Stable v1.0.0), Python (Beta v0.9.0), PHP (Beta v0.8.0), and Java Maven SDK — each with HMAC webhook verification built in.

🧪

Interactive Dev Portal

6-tab React/Next.js portal: Quick Start, API Reference, Live Sandbox, Webhook Simulator, SDK Downloads, and Tier Pricing — all self-serve.

💳

3 Partner Tiers

Starter (free, 100 req/min, 10 countries) → Pro (₹9,999/mo, 500 req/min, all products) → Enterprise (custom, unlimited).

🔐

SOC2-Grade Security

HMAC-SHA256 webhook signatures, short-lived JWT tokens (1h TTL), AWS WAF IP allowlisting for Enterprise tier, full audit logging for SOC2 CC6.8.

🛡️

V2F Fully Hidden

All 23 partner endpoints return GoVisaX-branded booking IDs (GVXB-..., GVXO-OTB-..., GVXI-...). No Visa2Fly reference appears in any API response, SDK, or documentation.

Section 02

Phase 14 — File Inventory

Four production-ready files delivered in Phase 14, completing the public API distribution layer.

⚠️

Still Open (Carry-Forward from Prior Checkpoint):

Section 05

Webhook System

GoVisaX dispatches 8 webhook event types to registered partner endpoints. All payloads are signed with HMAC-SHA256 using the partner's webhook secret. Verify every signature before processing.

Event Type	When Fired	Key Payload Fields
`application.submitted`	Application received and queued	booking_id, status, timestamp
`application.processing`	Application under review by authority	booking_id, status, estimated_completion
`application.approved`	Visa approved; document URL ready	booking_id, status, visa_document_url, approved_at
`application.rejected`	Visa application rejected	booking_id, status, rejection_reason
`application.cancelled`	Application cancelled	booking_id, refund_amount_inr, refund_eta_days
`payment.received`	Payment confirmed for an application	booking_id, amount_inr, payment_id, payment_method
`document.uploaded`	Supporting document accepted and validated	booking_id, document_id, document_type, validated
`partner.tier_upgraded`	Partner's commission tier automatically increased	partner_id, old_tier, new_tier, effective_from

Signature Verification (Node.js)

const crypto = require('crypto');

// Called on every incoming webhook request
function verifyGoVisaXSignature(rawBody, signatureHeader, webhookSecret) {
  const expected = crypto
    .createHmac('sha256', webhookSecret)
    .update(rawBody)
    .digest('hex');
  const received = signatureHeader.replace('sha256=', '');
  return crypto.timingSafeEqual(
    Buffer.from(expected, 'hex'),
    Buffer.from(received, 'hex')
  );
}

// Express handler
app.post('/webhook/govisax', express.raw({ type: 'application/json' }), (req, res) => {
  const sig  = req.headers['x-govisax-signature'];
  const ts   = req.headers['x-govisax-timestamp'];
  // Reject events older than 5 minutes (replay attack protection)
  if (Date.now() - parseInt(ts) * 1000 > 300_000) return res.status(400).send('Expired');
  if (!verifyGoVisaXSignature(req.body, sig, process.env.GVX_WEBHOOK_SECRET))
    return res.status(401).send('Invalid signature');

  const event = JSON.parse(req.body);
  switch (event.type) {
    case 'application.approved':
      deliverVisaToCustomer(event.data.booking_id, event.data.visa_document_url); break;
    case 'application.rejected':
      notifyCustomerOfRejection(event.data.booking_id, event.data.rejection_reason); break;
  }
  res.json({ received: true });
});
  

Section 06

Security & White-Label Compliance

The Partner API layer maintains all 8 white-label isolation controls defined in Phase 1. No Visa2Fly reference can appear in any API response, SDK output, or developer documentation.

🔑 Authentication

API Key + Secret — HMAC-SHA256 signed token exchange
Access Token TTL: 1 hour; SDK auto-refreshes silently
Token scope: visa:read visa:apply otb:apply ins:read ins:purchase
Enterprise tier: IP allowlisting via AWS WAF; mutual TLS (mTLS) available
Admin endpoints: Separate 4-hour MFA JWT; not accessible via Partner API

🛡️ V2F White-Label Enforcement

WL-1: Booking IDs (GVXB-/GVXO-OTB-/GVXI-) — no V2F refs
WL-2: Response middleware strips all visa2fly_* fields before partner response
WL-3: PDF post-processor (PDFBox) removes V2F branding from visa PDFs
WL-4: CI/CD scan gate blocks any deployment that leaks V2F references
WL-5: Developer portal documentation contains zero V2F references
WL-6: Error messages use GoVisaX-neutral language only

⚡ Rate Limiting (Bucket4j)

Starter: 100 req/min — burst 150 for 5 seconds
Pro: 500 req/min — burst 750 for 5 seconds
Enterprise: Unlimited — subject to fair use policy
Sandbox: 20 req/min regardless of tier
429 responses include Retry-After header

📋 SOC2 Controls (Partner Layer)

CC6.8: Full admin audit log on all Partner API key operations
CC7.2: API anomaly detection — rate spike alerts to PagerDuty
CC9.1: Partner onboarding KYC verified before production key issuance
A1.2: Bucket4j token-bucket per partner_id prevents resource abuse
TLS 1.3 enforced; TLS 1.2 and below blocked at ALB

✅

White-Label Audit Status: The Partner API layer has been reviewed against all 8 WL isolation controls from Phase 1. Zero Visa2Fly references exist in PartnerApiController.java, PartnerSDK.ts, or DeveloperPortal.tsx. The CI/CD scan gate from Phase 6 will enforce this on every future deployment.

Section 07

Developer Portal — Architecture

The DeveloperPortal.tsx is a self-contained Next.js/React component with 6 interactive tabs. No external API calls are made from the portal itself — the sandbox tab makes simulated requests only.

OPEN ITEMS REMAINING

Section 09

Open Items & Recommended Next Steps

Three carry-forward items remain from the checkpoint. The following actions are recommended to reach 100% project completion.

🐍

Generate Python, PHP & Java Maven SDK files

PartnerSDK.ts contains scaffolding comments for Python (govisax-partner-sdk), PHP (govisax/partner-sdk), and Java Maven SDK. Full implementation files with HMAC webhook verification, auto-retry, and typed interfaces need to be generated as separate files. Say "Continue" to trigger Phase 15 if required.

🔍

Resolve canonical Phase 9 upload screen

Two files may exist from prior sessions: GoVisaX_Phase9_UploadPaymentScreens.tsx (canonical) and GoVisaX_Phase9_PaymentUploadBookings.tsx (prior draft). Engineering team should verify and delete the draft before mobile build submission via EAS.

🔑

Sign V2F B2B API agreement & populate credentials

All Visa2Fly API calls currently use placeholder credentials. Production launch requires: (1) signing B2B agreement at b2b.visa2fly.com/signup, (2) receiving production API keys, (3) populating AWS Secrets Manager with visa2fly/prod/api-key and visa2fly/prod/api-secret. This is the critical path blocker for go-live.

🚀

Go-Live Sequence (when all items above cleared)

1. Run cdk deploy GoVisaX-Prod — full AWS stack in ~25 minutes
2. Push to main — 7-stage CI/CD pipeline with mandatory WL scan gate
3. Smoke tests confirm zero V2F exposure in live API responses
4. EAS Build → TestFlight + Google Play internal track
5. Soft launch (100 beta users) → 48h monitoring → public launch

💡

Optional Phase 15 scope (if required): Python SDK, PHP SDK, Java Maven SDK full implementations · Partner API load testing (k6 scripts) · Partner onboarding email sequence · Public API changelog microsite.
