Hi Elijah G, Thank you for your reply. I'm not sure about it, your links are used to create(POST)/get(GET) a campaign. I mean, i have a campaign and i want to send email to all member of a list, Please check attached file. When i check all methods at https://constantcontact.mashery.com/io-docs, not sure but i don't see any method to do a same action like /emailmarketing/campaigns/campaignId/tests yet. That method should have a campaignID (i think) Thanks and best regards, Khoa Pham
