Using quotes in transactions

When creating a transaction, include the quoteId and gasId to lock in the quoted rate:

curl -X POST "https://api.paytrie.com/transaction" \
  -H "x-api-key: your-api-key" \
  -H "Authorization: Bearer user-jwt-token" \
  -H "Content-Type: application/json" \
  -d '{
    "leftSideLabel": "CAD",
    "leftSideValue": 1000,
    "rightSideLabel": "USDC-ETH",
    "wallet": "0x742d35Cc6634C0532925a3b844Bc9e7595f8bC3a",
    "quoteId": 337362,
    "gasId": 186324
  }'

Quote rates are time-sensitive. If too much time passes between getting a quote and creating a transaction, the rate may change.
