FreeAgent now links directly with TransferWise! This package still works but there's no reason to use it.

1. Make sure you have node and npm installed
2. npm install
3. Copy .env.example to .env and populate each value.
4. Generate a public-private key pair:

openssl genrsa -out private.pem 2048
openssl rsa -pubout -in private.pem -out public.pem

Keep private.pem in the root directory of the app, and upload public.pem to your TransferWise account (Settings -> API Tokens -> Manage public keys)

FreeAgent does not fully support multi-currency bank accounts (at the time of writing), so they recommend that you add a separate bank account for each currency that you hold (see "A word on PayPal" at https://www.freeagent.com/blog/multi-currency-banking-arrives/)

You can specify multiple FreeAgent bank accounts as a comma-separated string in .env, e.g. FREEAGENT_BANK_ACCOUNT_ID="123,456". The script will loop through these accounts and import transactions from TransferWise that match the bank account's currency.

node index.js

It'll output a simple "Yep". Go to your FreeAgent account and the transactions since your last upload will be in the bank account, ready to be explained/confirmed.
