# Engineering reliable TRON Energy API orders

A practical integration walkthrough: preserve SUN precision, reuse a business order identifier, reconcile uncertain responses and verify callbacks before recording delivery.

## Define one business order before making a request

Create a unique client_order_id in your own database for the business operation. Store the requested Energy, duration and receiver alongside it before contacting the API. Use a uniqueness constraint so concurrent workers cannot create two local records for the same operation. This article describes a reference integration, not production results from a named customer.

## Quote the request you will actually submit

Call GET /prices/quote for the exact resource amount and duration. Store quote_id, the returned charge and expires_at together. Monetary fields are integer SUN strings; use an integer or decimal-safe representation. If the business request changes, obtain a new quote instead of editing the amount attached to the old quote.

## Sign the actual serialized request

Keep signing credentials on your server. Build the request body once and sign those exact bytes according to the downloadable contract and client. Do not sign one JSON representation and send a different one. Redact credentials and authentication headers from application logs.

## Persist the idempotency key too

POST /orders requires an 8–128 character visible-ASCII Idempotency-Key in addition to client_order_id. Persist the key and exact request bytes before submission. For a retry of an uncertain creation, keep both unchanged and generate a fresh timestamp, nonce and signature. Only replace an expired quote after resolving whether the previous creation was accepted. The public Skill describes webhook verification; address activation has no webhook and must be queried.

## Handle an uncertain order response

Submit POST /orders with the original client_order_id. If the connection times out, first query GET /orders?client_order_id={client_order_id}. A received order should be tracked, not replaced with a fresh identifier. If a retry is appropriate, retain the identifier and request semantics. Treat an idempotency conflict as a business error requiring inspection.

## Separate accepted, pending and completed

Save the platform order ID and returned status. Update local fulfillment state only from the documented terminal result and delivery evidence. Transport success alone is not proof of delegation. Preserve failed or review states so staff can resolve an exception instead of silently looping or charging twice.

## Verify and deduplicate callbacks

Follow the webhook verification rules in the contract. Reject invalid signatures; deduplicate the callback event ID before applying a state change. Acknowledge only after the event has been durably stored or processed. Tolerate duplicate delivery and reconcile using the order query API if local and remote states disagree.

## Bound retries and preserve an audit trail

Use timeouts, capped exponential backoff and a finite retry budget. Record client_order_id, platform order ID, status transitions and non-secret error codes. Use a queue or scheduled reconciliation in your application for unresolved orders instead of aggressive polling in the browser.

## Test the failure paths before production

Verify insufficient balance, expired quotes, duplicate business identifiers, timeout after acceptance, duplicate callbacks and invalid signatures in a controlled setup. Confirm that each case creates at most one intended business order and an explainable local record. The linked client and schema provide the actual wire contract; this article does not promise an SDK for every language.
