The machine-readable line of the bill is the numeric representation of the barcode. This information can be made available to your customer for payment of the bill directly through Internet Banking. When generating a charge with the payment methods BOLETO or UNDEFINED, the machine-readable line can be recovered.
To recover the machine-readable line of the bill, you must enter the charge ID that Asaas returned at the time of creation. In return, you will receive the machine-readable line.
Attention
If the charge is updated, the machine-readable line will also undergo changes. It is recommended that each time the charge is updated, the machine-readable line be recovered again, ensuring that you will always be displaying the updated machine-readable line.
