Any one using Zoho one in Brazil?

Any one using Zoho one in Brazil?

Hi there, I would like to find someone using Zoho One in Brazil.

  1. Can Zoho generate Brazil invoices (NF-e)?
  2. Can Zoho intregrate with Shipping service Correios Log+
  3. Is it easy to reliably call external APIs in a consistent and fault tolerant way (Retries, Replay, Monitoring, Exponential Back off, Idempotency, etc)
  4. Can I use Zoho one to be my identity provider for Shopify and other tools connected to Zoho One?

I have many other questions, but maybe a chat with someone experienced with Zoho One in Brazil would be better.
Any help would be appreciated 

Regards
