Manually Update Email Address and Mobile Phone in Contacts
You can now manually update a guest's email address and mobile phone directly from their Contact record or the Activity Stream. This makes it easy to correct typos, add missing details, and keep your records accurate.
When you update these details, OnceHub automatically syncs the changes across your notifications, calendar events and connected CRMs. If the updated email address or mobile phone matches an existing record, OnceHub intelligently merges the records while preserving the guest's entire activity history under a single record preventing duplicate contacts.
Key Benefits
Maintaining accurate contact details ensures that automated meeting reminders and notifications always reach the right person and your CRM records stay perfectly synced. Use this feature to:
- Correct typos: Fix errors in email addresses or phone numbers.
- Add missing details: If a guest schedules a meeting through the Phone Agent without providing an email address, you can add it directly to their Contact record.
Who Can Access It
Plan: Available on all plans.

OnceHub API: button_clicked Event Payload Update Complete
OnceHub has updated the button_clicked event payload for Chatbots and Routing Forms to standardize the data structure across all question types.
The booking_calendar_name property has been deprecated and removed and is now sent exclusively in the question_text property.
If your integrations reference booking_calendar_name, you must update them to the question_text property. Integrations that are not updated will no longer receive the Booking Calendar name data.
For implementation details, refer to the updated event documentation in the OnceHub Developer Center:
- Embedded Chatbot Events: Embedded Chatbot Events: oncehub.chatbot.button_clicked
- Embedded Form Events: Embedded Form Events: oncehub.form.button_clicked
