[ARCHIVED] Creating user via API: user "is already in use", but cannot be found

[zoltansz]

Dear all, I am developing an Azure Logic App that automates creating Canvas users via a Python language Azure Function using the canvasapi Python package.

Everything is working fine, but when I delete the user manually and re-run my workflow with the same data, it fails with error 400: "(email address) already in use".

It is the same if I use Postman. The second run after deletion fails.

Can I recycle SIS IDs, email addresses and other unique properties when creating new objects?

If not then how can I erase those deleted object finally?

Thanks, 

Zoltán
