fees resource represents a monetary assessment against an account holder’s general purpose account (GPA). Assessing a fee transfers funds from the account holder’s GPA account to your program’s fee account. By default, every account has a GPA account used for the funding of transfers.
You can assess fees either post-transaction or in real time. Real-time fee assessment ensures the account has sufficient funds available to cover both the transaction amount and the fee before authorization of the transaction. To assess fees in real time, you must create a real-time fee group using the /realtimefeegroups endpoint.
When assessing a post-transaction fee, you can either debit existing GPA funds, or pull in new funds from a funding source. To use existing GPA funds, use the /feetransfers endpoint. To pull in new funds, use the fees array in /gpaorders.
Note
