# Sell Resources

Manually sell Energy or Bandwidth on TronSave by matching active buy orders with a signed on-chain delegate transaction.

The Sell Resources API lets a resource provider manually fill open buy orders on TronSave. The seller fetches active orders, builds and signs an on-chain `DelegateResourceContract` transaction, then submits the signed transaction to TronSave for order matching and payout.

{% hint style="warning" %}
**Whitelist required.** The Sell API is restricted to whitelisted wallets. Log in to TronSave and send your wallet address to support to add it to the whitelist. Once whitelisted, use the API Key generated from that wallet address to call the Sell endpoints.

Selling is a two-step flow:

1. [**Get active orders**](/developers/api-reference/sell-resources/get-active-orders.md) - list open buy orders you can fill.
2. [**Sell the resource**](/developers/api-reference/sell-resources/sell-the-resources.md) - submit a signed delegate transaction against a chosen order.
3. [**Get Delegate Detail**](/developers/api-reference/sell-resources/get-delegate-detail.md) - get detailed information and the current status of a specific delegate using its delegateId.
