Create a Payment Transaction

📘

Source qualifier & source identifier

The source_qualifier is an identifier of the payment transaction source, usually a bank, such as 'barclays'.
All payment transactions that belong to an invoice must have the same source_qualifier as the invoice.

The source_identifier must be unique per source_qualifier, company-wide.

These values must only contain the characters a-z, 0-9, _ and -, with a maximum length of 50 characters.
