I have a scenario, where a large user base exists in a CRM application. Now the business wants to develop a portal with a login functionality. Whats the optimal way to check if the user exists in the CRM during the sign-up process? Can i call the CRM API to see if the user exists?

You can check that either using your or our storing system. We have an API for that which is called Management API: [image] Auth0 Management API v2

Check if the user exists in a CRM on sign-up

Hey there @zeeshi!

I need you to explain to mee the whole usecase. Why you want to check whether user exist?

To show them that they can login cause they already have an account or for other purpose?
