I have provided my API key in an email to firstname.lastname@example.org for enabling scheduling/sending email using API. My login is email@example.com. Please enable this ASAP.
Also, I would like to know whether I can store templates in ConstantContact, so while calling the schedule/send fuction crom Salesforce, I can specify the template to use.
Yes, I got your email and will handle it all by emailing you with the information I need to give you access. Thank you for your interest in our scheduling API!
