Fix: api.hashpass.tech DNS Configuration

Current Problem​

api.hashpass.tech is currently pointing to Amplify Hosting (CloudFront), not API Gateway. This is why you're getting 404 errors.

Evidence:

  • DNS resolves to CloudFront IPs: 18.155.252.x
  • HTTP response shows: server: AmazonS3 and via: CloudFront
  • Returns 301 redirects instead of API responses

Solution Options​

Prerequisites:

  • API Gateway must be configured with custom domain api.hashpass.tech
  • Lambda function must be deployed

Steps:

  1. Get API Gateway Domain Name:

    • Go to API Gateway Console → Custom Domain Names
    • Find api.hashpass.tech domain
    • Copy the "API Gateway domain name" (e.g., d-xxxxx.execute-api.us-east-1.amazonaws.com)

  2. Update DNS in Route 53:

    • Go to Route 53 → Hosted Zones → hashpass.tech
    • Find CNAME record for api
    • Update the value to the API Gateway domain name
    • Save

  3. Wait for DNS propagation (usually 5-15 minutes)

  4. Test:

    curl https://api.hashpass.tech/api/config/versions

Option 2: Use Different Subdomain for API Gateway​

If you want to keep api.hashpass.tech for Amplify Hosting:

  1. Create new subdomain (e.g., api-gateway.hashpass.tech or api-proxy.hashpass.tech)

  2. Configure in API Gateway:

    • Create custom domain with new subdomain name
    • Map to your API

  3. Update DNS:

    • Create CNAME record for new subdomain
    • Point to API Gateway domain

  4. Update frontend code:

    • Change EXPO_PUBLIC_API_BASE_URL to new subdomain

Option 3: Use Cloudflare Pages (Alternative)​

If API Gateway is too complex, use Cloudflare Pages which handles API routes automatically:

npm run deploy:cloudflare

Then update DNS to point api.hashpass.tech to Cloudflare Pages.

Verification​

After making DNS changes:

# Check DNS resolution
dig api.hashpass.tech

# Should show API Gateway domain, not CloudFront
# Example: d-xxxxx.execute-api.us-east-1.amazonaws.com

# Test API endpoint
curl https://api.hashpass.tech/api/config/versions

Current DNS Status​

Based on verification:

  • api.hashpass.tech → 18.155.252.x (CloudFront/Amplify Hosting) ❌
  • Should be → API Gateway domain ✅

Next Steps​

  1. If API Gateway is configured:

    • Update DNS CNAME to point to API Gateway domain
    • Wait for propagation
    • Test endpoint

  2. If API Gateway is NOT configured:

    • Follow API-GATEWAY-TROUBLESHOOTING.md to set up API Gateway first
    • Then update DNS

  3. Alternative:

    • Use Cloudflare Pages for API routes (simpler, free)
    • Or use Netlify Functions
