# Give me a price, date, text, and email links
# I upload these if they match a debit from the monzo account (date close and price match)
# Fails in the event of multiple matches, returns false

# Download transactions around the date of the data
# Match price, if one match succeed, if multiple pick closest date, if still multiple fail
# Upload data - text & link in notes, (email screenshot as receipt?)
