What is a Reseller API?

A reseller API is a programmatic interface that lets a reseller business automate operations on a white-label platform — including customer account creation, product provisioning, billing events, and account suspension. APIs replace manual dashboard operations with code, enabling scale beyond what a single human can manage.

What a Reseller API Does

A reseller API exposes the same operations available in the platform’s admin dashboard, but as HTTP endpoints. Instead of clicking “Create Customer” in a UI, your code makes a POST request to /customers and the platform returns the new customer’s ID. This lets you automate signup flows, billing, and provisioning.

Common Reseller API Operations

• Create customer accounts — POST /customers with email, name, plan
• Activate products — POST /products to enable a product for a customer
• Update billing — PATCH /customers/{id}/billing to update payment method
• Suspend accounts — POST /customers/{id}/suspend for non-payment
• Fetch usage — GET /customers/{id}/usage for billing-relevant metrics
• Webhook subscriptions — Subscribe to events like new signups, churns, payment failures

Why Resellers Need an API

• Custom signup flows — Build your own signup UI that creates customers via API
• Billing integration — Connect Stripe, WHMCS, or other billing platforms
• Automation — Provision customers automatically after payment
• Scale — Handle thousands of customers without manual dashboard operations
• Custom dashboards — Build your own admin tools on top of the platform

API Authentication

Most reseller APIs use API key authentication: the reseller generates a secret API key in their admin dashboard and includes it in the Authorization header of every API request. Keys should be kept secret and rotated periodically.
