| - | Also in the UK, (fixed) prices are known to change at the half hour instead of the whole hour (where our system works with). The work-a-round is to add the average price of in the overlapping hour. So if the price changes from 40 cents to 20 pence at 16.30, fill out a price of 30 pence from 16.00 - 17.00. | + | In addition to your API key, VRM will need your account number and information about your payment method |
