Hello every one.
I want to use Subscribe newletter to send email. I want to develop this in c#(.net) please share some link or sample, regarding this.
Thank you for reaching out to the API Support team here at Constant Contact.
It sounds like you are looking to create a signup form using C#. We have a .Net wrapper for our API which can be used. I recommend first reviewing our base API documentation and then looking into our .Net wrapper. I have linked both below.
Get started with our API: https://developer.constantcontact.com/get-started.html
.Net wrapper for our v2 API: https://github.com/constantcontact/.net-sdk
Please let me know if you have any other questions!
