Need access token for all the multiple accounts on one account

[TimeAnalytics]

Hi There,

I need to access the insights for all the accounts using API. However, I am unable to find a way to get the access token for all the pages (brand accounts). I have created an access token using this URL (https://apps.twitter.com/ ) but unable to access the insights for all the accounts.

Let me know if i am clear on this.

Thanks,
