Rheo Developer Docs
Connect your inventory to Tradera and the Rheo marketplace in minutes.
What is the Rheo Integration API?
The Rheo Integration API lets B2B partners — demolition plants, parts dealers, wholesalers — push inventory into Rheo and have it automatically published as Tradera auctions.
One PUT call per item. Rheo handles the rest:
- Downloads your images and stores them on our CDN
- Publishes the item as a Tradera auction under your account
- Monitors the auction every 15 minutes
- Sends you a signed webhook when anything changes — listing live, sold, ended
Key concepts
| Concept | Description |
|---|---|
external_id | Your internal item ID (e.g. ERP part number). Used in all API calls. Rheo never changes it. |
x-api-key | Authentication header for item sync. Generated in the Rheo partner dashboard. |
| JWT | Supabase session token. Required for management and analytics endpoints. |
| Webhook | Signed HTTP POST Rheo sends to your endpoint on listing events. |
X-Rheo-Signature | HMAC-SHA256 header on every webhook. Verify it before processing. |
