Overview
If custom field data isn’t appearing on your leads (either via import or form capture), it’s usually a mapping or visibility setting issue.
Procedure
Confirm the custom field exists under Settings → Custom Fields → Lead and is Enabled.
If data was imported: revisit Leads → Import, upload your file, and ensure you mapped the spreadsheet column to the correct custom field.
If data came from forms: go to Leads → Lead Form, make sure the field is toggled On and that its API key matches your integration.
Check the lead record’s Permissions (sometimes admin‑only fields are hidden from other roles).
Save any changes and reload the lead detail page.
Tips
Use consistent field labels and API keys across your CSV and forms.
Test by manually editing a lead in the UI to see if the field appears.
Archive unused custom fields to declutter your forms and filters.
Troubleshooting / FAQs
Field shows blank after mapping: Check for leading/trailing spaces in your CSV header.
Form capture not populating field: Verify your embed code includes the field’s data-field="custom_xxx" attribute.
Field visible in UI but not in export: Ensure you selected that column in your Export dialog.
