Map registration fields to integrations
Registration field mapping controls which custom question responses are sent to connected CRM and email integrations. Use it when a field should become a usable property in the external system, not just stay inside HeyStream.
Before you start
Connect at least one CRM or email integration that supports custom field sync.
Create or edit the registration question you want to sync.
Decide whether the response is useful for follow-up, qualification, segmentation, or reporting outside HeyStream.
Map a field
Open the broadcast, series, or question library area where the registration question is managed.
Create a new custom question or edit an existing one.
Find the Sync to Integrations section. It appears when there is an active sync-capable integration available.
Select the integration connections that should receive this field value.
Save the question or broadcast settings.
How values are sent
HeyStream uses the registration question label to create a readable external field key.
Text, select, and choice responses are sent as formatted text values.
Checkbox responses can be sent as true or false values where supported.
Only selected fields are elevated into the contact record for the selected integration connection.
Field mapping tips
Keep labels stable after syncing begins so external field names stay predictable.
Avoid syncing sensitive or internal-only questions unless your external system is approved for that data.
Use mapping for fields your team will actually use, such as company size, role, goal, product interest, or buying timeline.
