Sorry for the delayed reply.
According to Instagram the APIs (used to get the account data) are no longer available:
…Instagram Legacy API permission (“Basic Permission”) was disabled on June 29, 2020. As of June 29, third-party apps no longer have access to the Legacy API.
Zapier can’t access anything other than posts.
Have a look at Fanpage Karma – you may get the information you want. But, from last time I checked, the way their API works it may be cost prohibitive.
As mentioned earlier the abuse by some companies has meant most of the APIs used to get user data have been shut down.
Good luck
Mike
