Redirect URL - Invalid


Redirect URL - Invalid



I have been trying to get Oauth to work using Server Flow.  I am unable to get anywhere as the redirect URL is incorrect.  I am using localhost with no success.


Any assistance would be greatly appreciated.

Thank you for reaching out to the Community! The only reference I was able to find in regards to Oauth is in this article: Setup And Overview Of The BigCommerce x Constant Contact Pro Integration in the section titled Requirements for Setup. Our Tier 2 team can offer additional assistance with the BigCommerce integration. Just call our Support team at 866-289-2101 and they can get you to Tier 2. 


If this is not a BigCommerce issue, but is in reference to the Constant Contact  API I recommend sending an email to
