Motivation and Context

#3307

How did you test it?

Testing can be done by creating 2 manual authorized payments for Bankofamerica. While creating these payments you should pass metadata in the requests.

"metadata": {
    "count_tickets": "1",
    "transaction_number": 2233
 },

Then you should void one payment and capture the other. You should then be able to see this metadata in merchantDefinedInformation in BOA Dashboard.
