Zoho CRM Authorization Failure
"An error occurred. Failed to login with the provided credentials: WEB_LOGIN_REQUIRED"
This error is caused by the fact that Flatly cannot facilitate the 2-Factor Authentication step provided by Zoho CRM.
You do NOT need to disable 2-Factor Authentication in Zoho CRM.
Setup an app-specific password for Flatly as outlined in these Zoho CRM docs under "In the Two Factor Authentication page, click on the Manage Application Specific Passwords"
