To use any of the above modules, you need to have VTiger CRM accessible from the Internet and a VTiger CRM account. If you do not have VTiger CRM accessible publicly or you do not have a VTiger CRM account, then contact your system administrator or VTiger CRM administrator.
To connect your VTiger CRM account to Integromat, follow the general instructions for Connecting to services. You also have to specify the address of your VTiger CRM instance and access key. In order to get it, go to VTiger CRM -> My Preferences.
After you click the Continue button, Integromat will validate the connection and you can continue creating your scenario.
