How can I retrieve a salesorder's primary contact using the REST API?

AI generated answer (using internal Slack threads):

To retrieve a sales order's primary contact using the REST API, you can use the

Contact (Primary)

join. This join will allow you to access the primary contact associated with a sales order. However, if you need to access all contacts from a customer record on the sales order, you could create a custom sublist off of a contacts saved search with available filter=company and expose that to one of the tabs of your sales transactions. It will show you all contacts with Company=Customer of your sales order. If you need to know which contact created the order, you might need to create a custom transaction body field for

custbody_customer_contact

. There isn't a standard field for this information. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
