Is it possible to retrive the 'account' associated with a xero bank transaction

Question

I'm using Xero's private API to export bank transactions (so I can automate a bunch of financial reporting).

Retrieving the transactions works well (as documented here https://developer.xero.com/documentation/api/banktransactions) but this endpoint doesn't return the account field associated with each transaction, which I want to use to group the transactions into e.g. "Cost of sale", "Operating expenses" and so on.

Does anyone know of a way to find the account for a given transaction via the API?

Further info:

• If the transaction contains line items, then the account associated with each line item is returned by the endpoint above. I'm mostly interested in transactions that do not include line items (the LineItems field is an empty array)
• Most of the transactions i'm working with are of the "Spend Money" type
• I'm currently using pyxero SDK, but open to other options
• The account field is present in Xero's web interface, and on the CSV export available from the web interface.
• Our contacts in Xero don't have default accounts.

Answer 1

It is the LineItems of Bank Transactions that have AccountCodes associated with them and I've not been able to find a bank transaction record without a line item in the data I have available to me.

Is it possible that you are not implementing paging? From the bank transactions documentation you linked to above:

Paging BankTransactions (recommended)

To utilise paging, append a page parameter to the URL e.g. ?page=1. If there are 100 records in the response you will need to check if there is any more data by fetching the next page e.g ?page=2 and continuing this process until no more results are returned.

By using paging all the line item details for each bank transaction are returned which may avoid the need to retrieve each individual bank transaction.

I'm not familiar with the pyXero implementation, but it looks like they support Xero paging. From the pyXero readme:

# Grab 100 invoices created after 01-01-2013
xero.invoices.filter(since=datetime(2013, 1, 1), page=1)
