Receipts and payments mapping missing with invoice in receiptspayment api

Please can you provide Invoice key object to identity payment is made for which particular invoice.

Please provide asap![missing important info for managerio team|

Not clear what you are looking for.

You can pick the invoice to allocate the payment to when entering a receipt

The purchase invoice number you have outlined on your payment form is one you entered on one of your purchase invoices for Associate Timbers. There is no “Invoice key object” to provide.
