Quick Start

Integrate our API into your backend in seconds using standard HTTP tools like cURL.

curl -X POST "https://reseller.co.tz/api/v1/domains/check" \
  -H "X-API-KEY: your_reseller_api_key" \
  -H "Accept: application/json" \
  -d '{"domain_name": "example.co.tz"}'

Authentication

All API requests must be authenticated using your unique API key found in the Reseller Portal.

Header Value
X-API-KEY Your unique reseller API key
Accept application/json

Response Formats

Every v1 response uses a predictable JSON envelope. Registry and DNS errors are intentionally general so provider details, private configuration, and credentials stay hidden from public integrations.

Best practices

  • Call the API from your own backend only. Never ship the key inside browser JavaScript or a public mobile app bundle.
  • Store the key in an environment variable or secret manager, and whitelist the server IP in the reseller portal.
  • Show customers the friendly message; keep raw responses and technical detail in your own logs.
  • Never log or display Auth/EPP codes.
  • Billable calls are not idempotent, so add your own retry guard before repeating a registration or renewal.
  • After a transfer, poll POST /domains/{domain}/sync instead of assuming the move finished instantly.
  • Countries must be ISO 3166-1 alpha-2 codes: Tanzania TZ, Kenya KE, South Africa ZA.

Legacy API Support

Older integrations can continue posting action-based requests to the legacy endpoint. New projects should use /api/v1 because it is easier to validate, audit, and extend.
