=head2 post_upload
Takes a file upload, with a file key of 'file2', and a json string under the
'json' key.
The json string should be an object, with the following keys:
=over
=item * microCurrencyValue
The value of the transaction
=item * transactionAdditionType
Is a value of 1, 2, or 3 - depending on the type of transaction.
=item * addValidatedId
An ID of a valid organisation. used when transactionAdditionType is 1.
=item * addUnvalidatedId
An ID of an unvalidated organisation. Used when transactionAdditionType is 2.
=item * organisationName
The name of an organisation. Used when transactionAdditionType is 3.
