We are calling https://api.cc.email/v3/idfed with our client id from code in web browser control so that user can authenticate the request and allow permissions.
but again and again we are seen captcha screen only even we enter correct details is not moving further.
Please advice us what to do.
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.
If the method you are using (browser control) is having difficulties displaying captcha and is preventing user accounts from connecting, then it may be outdated or unsupported.
Please feel free to contact us directly via email at email@example.com with the language/platform you’re using, as well as samples/screenshots of any errors you are encountering so that we can look into this and investigate further with you as a courtesy.
We are limited in the support we can provide regarding the implementation of the API in any specific language or setting, but will try to answer any questions to the best of our ability as they pertain to Constant Contact’s API endpoints and functionality.
