* `currency` - Three digit currency code representing which coin the request is based on
* `requiredFeeRate` - The minimum fee per byte required on this transaction. Payment will be rejected if fee rate included for the transaction is not at least this value. _May be fractional value_ ie 0.123 sat/byte
* `requiredInputConfirmations` - The minimum number of confirmations on the blockchain for each transaction input. Can be 0 which means that the input is unconfirmed but needs to be broadcasted and found in the servers mempool.
* `outputs` - What output(s) your transaction must include in order to be accepted
* `time` - ISO Date format of when the invoice was generated
* `expires` - ISO Date format of when the invoice will expire

Another issue you may see is that you are being redirected to `bitpay.com/invoice?id=xxx` instead of being sent a payment-request. In that case you are not setting your `Accept` header to a valid value and we assume you are a browser or other unknown requester.
