Auto-Converting Crypto Balances With the Convert API

CoinGate has launched a Convert API designed to automate the conversion of cryptocurrency balances within its platform. The service allows users to move value between supported currency pairs, such as Bitcoin to euro or euro to USDC, directly on their CoinGate account ledger. This eliminates the need for manual conversions through the dashboard, streamlining treasury management for businesses accepting multiple cryptocurrencies. The API operates by locking a rate for a short window, ensuring users can review the exact amount before confirming the conversion. The Convert API targets users who accept payments in various cryptocurrencies but prefer to manage balances in a single reporting currency, such as euro or USDC.

The API workflow begins with a quote request, which provides a locked rate valid for a limited time. Users must confirm the conversion within this window, typically around 65 seconds, before the quote expires. The process involves three key inputs: the source ledger account ID, the target currency numeric ID, and the base amount to convert. Responses include critical details like the expected quote amount and the expiration timestamp, which users must monitor to avoid missed conversions. The API returns confirmation and cancellation URLs, simplifying the process and reducing the risk of errors in automation scripts.

Once confirmed, the conversion executes, updating the source and target account balances while applying a fee. The status changes to completed, and the transaction is recorded for future reference. If a user attempts to confirm an already completed conversion, the API returns a 422 error, preventing duplicate actions. This design ensures that only valid, pending conversions are processed, maintaining the integrity of automated treasury sweeps. The API also supports cancellation, which releases the locked quote without altering balances, providing flexibility in dynamic environments.

To implement automated treasury management, users can settle payments with a DO_NOT_CONVERT flag to retain original coins, then schedule a job to convert balances into a reporting currency like euro. The Ledger API retrieves current balances, and the Convert API handles the conversion process. Past conversions can be reviewed via the /v2/ledger/conversions endpoint, which returns a list of exchange transactions. This approach mirrors the mechanics of crypto treasury management, enabling businesses to consolidate holdings efficiently while minimizing manual intervention.
