On digistore24.com, we allow our users to have multiple accounts.
Whenever user connects a second account to constant contact, the connection of the first account is cut.
The reason is, that the first refresh_token becomes invalid - see
We need to be able to retrieve a constant contact account id, so that we store it with the refresth token and know, which old refresh tokens to replace.
How can we do this?
Thank you for reaching out to Constant Contact API Developer Support.
We are still in the process of building out the feature set of our V3 API. As of right now there aren't any account summary endpoints that would provide you with this information, however we are hoping to have these included in our release at the end of May or beginning of June. Obviously I can't guarantee that, but that is currently what we are shooting for.
