This guide walks through an example Workflow that automatically associates new HubSpot contacts with their company. The Workflow triggers when a contact is created, extracts the domain from the contact’s email, looks up a matching company by that domain, and creates an association between them.
Add a Create Association action
In the Workflow builder, click the + button between existing blocks. Select Create Association from the action list.
Connect your HubSpot account
Rename the action (optional)
Enter a more descriptive name to make the action easier to reference as a variable later.
Set up preceding actions
To use the Create Association action, configure earlier steps in your Workflow to provide the record IDs you want to associate. For example:
- Add a trigger such as HubSpot Contact Created to activate the Workflow when a new contact is created. Click Add Filter to narrow which contacts trigger the Workflow.
- Add a Look Up HubSpot Record action to find the record you want to associate with. For example, search for a company by domain name using a variable from the trigger.
