Hey ​@luismi,

Unfortunately it is still not possible to export / access revision history via API as far as I am aware. There is no reference to revision history or similar on Airtable’s API docs. 

This has been discussed previously on multiple community posts (see alternative solution -forward looking here. It is still pretty clunky though).

Would be great if you could submit this as a feature request using this form.

Re: revision history over the portal. Do you mean interfaces or Airtable Portal? -pretty much the same thing. For interfaces, absolutely. For portals, I’m 99% sure that revision history gets also transfered with their corresponding user but I’ll double check for you.
