Code Examples
End-to-end, copy-paste code examples for buying and extending Energy and Bandwidth through the TronSave API.
These pages contain complete, runnable scripts that walk through a full TronSave integration end to end — from building and signing a transaction to placing an order and confirming it was filled. Each example is self-contained: copy it, set your credentials, and run it.
The examples come in two flavors:
API Key — authenticate with a TronSave API Key. Best for backend services that pay from a prepaid TronSave balance. See Authentication.
Private Key — sign and pay directly from a TRON account using its private key, no prepaid balance required.
All examples use TronWeb 5.3.2. Install it with:
npm i [email protected] @noble/[email protected]Read more in the TronWeb 5.3.2 release notes.
Most examples reference the mainnet TronSave receiver address TWZEhq5JuUVvGtutNgnRBATbF8BnHGyn4S. When running against testnet (Nile), change it to TATT1UzHRikft98bRFqApFTsaSw73ycfoS. See Environments & Networks.
