Add and update contacts in marketing events with workflows

Last updated: April 30, 2026

Use a workflow to automate the process of adding contacts to and updating the participant state of these contacts in your marketing events.

Please note: this action only works for marketing events manually created in HubSpot. It cannot be used for events synced via integrations.

In your HubSpot account, navigate to Automation > Workflows.
Click the name of an existing workflow, or create a new workflow.
Click the + add icon to add a workflow action.
In the left panel, click to expand the Marketing section. Then, select Add participant to marketing event.
Configure your workflow action:
- Contact: this will be set to the enrolled contact by default.
- Marketing event: select your marketing event. This will only apply to manually created marketing events. Marketing events created from third-party integrations will not appear.
- Mark contact as: the contact participant stage. You can select from Registered, Attended, or Cancelled.
- Started attending at: the date and time the contact attended the event. This is an optional field.
- Finished attending at: the date and time the contact completed the event. This is an optional field.
After setting up your workflow action, at the top, click Save.
Continue setting up your workflow.
