Transactions

Create transactions to buy or sell stablecoins. Transactions require an authenticated user (via JWT token) and process payments through Interac e-Transfer.

Transaction flow

Get a price quote

Fetch current rates using the Price Quotes endpoint.

Create transaction

Submit the transaction with the quote details.

User sends payment

For buy transactions, the user completes the Interac e-Transfer using the reference number. For sell transactions, the user sends USDC from the wallet address provided.

Processing

Once payment is received, Paytrie processes the transfer.

For buy transactions, stablecoins are sent to the user's wallet and the transaction status updates to complete. For sell transactions, CAD is sent to the user's e-Transfer email address and the transaction status updates to complete.
