OAuth Server Flow issue Cannot get the whole State back the state is being altered/truncated.

[user306712]

While Trying to integrate Constant Contact with OAuth Server Flow there is an issue I am facing, I am unable to get the whole state back, the state is being altered/truncated.

For example . When I am requesting Constant Contact Service with the following url: URL:https://api.cc.email/v3/idfed/<client id> &<redirect_uri> & <response_type> & <scope> & <state>.

I am unable to get the whole state along with the auth code in my redirect uri, and also when I remove '&' symbol before the state in the URL mentioned above then I am able to get the whole state back properly.

So the following are the questions which I want a clarification/help on:

Why is it that the query parameters cannot be passed through state?

Thank you for reaching out to Constant Contact API Developer Support, my name is Caleb. My team is here to assist outside software developers with questions about building into Constant Contact's API.

We do support the use of the state parameter, however with the parameter not being passed through successfully we believe that the value that is being used may be the source of the issue.

To further test this issue we'll need some additional information. If you could please provide us with examples of the request using the state parameter we'll be able to better assist in pinpointing the cause of the parameter not being passed through. Please provide this information securely by reaching out to us via email at webservices@constantcontact.com, we look forward to assisting you!
