From the Chatbot -> Integrations section it is possible to connect to various external CRM systems:
Pilot integrates via an email address.
Base uses a token that the user gets from BaseCRM.
Uses a token that the user gets from Tokko CRM.
Uses a token that the user gets from Sumaprop.
Tecnom is integrated through an email address.
With any other system we recommend that you take a look at the integration with Zapier, which allows you to integrate with more than 1000 services in the cloud.
