Integration guide

How Letacom APIs will work

All Letacom APIs follow the same conventions, so one integration pattern works across products.

1. Request access. Submit an API access request with your intended use.
2. Receive your key. On approval we email an API key. Keep it server-side; never embed it in browser code.
3. Call over HTTPS. Send JSON requests with the key in the Authorization header.
4. Handle responses. Successful calls return JSON with HTTP 200; errors return a JSON error object with a 4xx or 5xx status.

Example request (illustrative)

curl -X POST https://api.letacom.co.za/v1/vat/calculate \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{ "amount": 1150.00, "mode": "inclusive" }'
