New features: Transaction API and Reporting API

The Transaction API now supports the following request objects:

• additional_recipients — data type representing an additional recipient
  (in other words, a recipient other than the merchant or Square) receiving a
  portion of a tender.

The new Reporting API includes two endpoints that let you pull information about distributions you have received as an additional recipient:

• AdditionalRecipientReceivables — returns a list of receivables (across
  all source locations) representing monies credited to the given location ID by
  another Square account using the additional_recipients field in a transaction.

• AdditionalRecipientReceivablesRefunds — returns a list of refunded
  transactions (across all source locations) related to monies credited to the
  given location ID by another Square account using the additional_recipients
  field in a transaction.
