I’m facing this challenge at PencilFuel.com
Upon successful purchase, I want to remove an existing Contact from a SendGrid list (Leads), then add it to another list (Buyer) automatically.
Keeping my list clean and tidy (Leads are leads, Buyers are buyers). The outcome would offset the risk of emailing contacts twice or more while blasting them or creating further email automation.
I don’t know where or how to identify the parameter contact_ids. Can you please help me locate this field?
I might be receiving feedback from the plugin author (post here), but asking you all in case somebody already have the answer and can point me to the right direction.
