Hi!
We have a developer token that we use every day to create, refresh and report on numerous campaigns for clients we have under our MCC account. It works fine.
Now, we are developing an application to access data from other Adwords customers (but not within our MCC). The goal is to provide an analysis of their AdWords and provide hints on how to improve things. It will be a one-time access, using the OAuth2 Web App flow. We will not save the refreshed token.
When we applied for our developer token a year and a half ago, we submitted it was for our own internal data (installed app).
Since we want to create this new application, fetching data from someone else's account, I wonder if we need to apply for a second, distinct, Developer Token. I initially thought so, but when I reviewed the API section of the Configuration panel of the MCC account, I saw only one spot for a developer token that made me doubt if we could apply for a second token.
Thanks,
Sylvain
