I want to create a service where a client with an existing adwords account can be linked to my MMC account in the following way:
There is a button that when clicked, shows a popup window where the user authenticates and accepts the link. Can you do this?
So far as I read in the documentation and forum to accept the invitation, I send you a link to the adword console so that you can log in and accept the invitation, or provide me with your clientId, ClientSecret, RefreshToken keys to accept the invitation with the api but that is more laps for the client
