Hello user928830,
Thank you for reaching out to Constant Contact API Developer Support. My team is here to assist outside software developers with questions about building into Constant Contact's API.
Thanks for your reply! Your feedback and experience with this request is essential to improving our product, so thank you for reaching out to us regarding this matter.
We're currently making updates to our authentication system. This work would need to be completed prior to implementing additional authentication flows, however we are looking into them as future options. Some of the options currently under consideration include: Client Credentials flow, the Device Authorization flow, static refresh tokens, etc.
If you have a specific use case or auth type that you feel would better meet your needs, we’d love to hear from you. If possible, please include what specific solution(s) you’re looking for, whether your app would only access your own Constant Contact’s account data or if it would also be used by other accounts, etc. You can reply here, or contact us directly via email at webservices@constantcontact.com.
Regards,
