Authentication

The ResellerClub API uses API key authentication. Use the Authorize button in the top bar to set credentials once — they apply to all endpoints across every API group.

When multiple API environments are configured (for example Sandbox and Live), choose the target in the API environment dropdown inside Authorize. Credentials are stored in your browser; use sandbox credentials against the Sandbox API and live API credentials against the Live API.

Authentication headers

Send both headers on every request:

• Authorization — uses the ApiKey scheme: Authorization: ApiKey YOUR_API_KEY
• X-User-Id — your reseller user ID

In the Authorize dialog, enter your API key only (without the ApiKey prefix); the playground adds ApiKey automatically when sending requests.

Example:

Using the Authorize button

1. Click Authorize in the top bar
2. If shown, pick Sandbox or Live (or another configured target) from API environment
3. Enter your X-User-Id and API key (the ApiKey prefix is added for Authorization automatically)
4. Click Test on any endpoint — credentials and the selected base URL are included automatically

Credentials persist for your browser session while you browse the documentation.
