To create new invoice send a GET request to the /api/merchant/v1/startpayment
The difference between /startpayment and /createinvoice methods is that the first one doesn't require the secret_hash parameter to be included in the request and also the checkout currency is not predefined here. Users can choose their preferred payment method right on the checkout page.
A successful /startpayment request will create a hosted checkout page https://www.cryptonator.com/merchant/invoice/<invoice_id>.
Once user chooses preferred payment method, Cryptonator generates unique payment address, calculates payable amount in cryptocurrency and sends HTTP-notification with all the invoice parameters to the provided callback URL.
