Invalid Token Error

[user315092]

I tried to run some API calls today that were running fine last week. I am getting the following error: 
"error_key":"http.status.authentication.invalid_token","error_message":"Invalid access token:" 

I'm using the same access token I've used for the last 8+ years. I don't think I can generate a new token because I'm using API v2 and it sounds like you shut down the ability to generate new v2 credentials. 

Please advise.

Hello user315092,

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.

While the ability to create new V2 API keys has been retired, you are still able to generate a new access token programmatically if needed.

If you continue to run into this issue, could you please reach our team directly/securely via email at webservices@constantcontact.com referencing case #33266664 and include the API key you are using so that we can provide further instructions?

Please have a look and let us know if you have any other questions!
