Notification History

Use Notification History to view past SMS notifications for an individual user’s phone number. This allows your staff to verify if a user’s two-factor authentication notifications were delivered and see delivery logs for any SMS alerts that the user has set up. Only SMS notification history is shown. Voice call history to landline phone numbers is not shown. 

To enable Notification History, add the permission "Can view notification history" to the appropriate staff user roles. Admins will be able to access it by default. To open Notification History, from the Admin Platform, select the cog wheel, then select Notification History.

Note: This tool is not available in UAT environments because SMS messages do not send in UAT.

Enter the phone number in the Destination phone number field. If accessing Notification History from the user's profile, the user's phone number is auto-populated in this field. Select Fetch SMS Notification History. A list appears showing the content of each message, along with the Date, Status, Body text of the SMS message, From number, and To number. Verification codes in the body text are hidden for security.

Possible statuses are:

• Delivered – Twilio has received confirmation of message delivery from the carrier and the destination handset (where available).
• Delivery unknown – This indicates that a message has remained in the sent status for longer than 1 hour without receiving a further status update. Select the info icon to view the Twilio error code.
• Failed – The message could not be sent. This can happen for various reasons including queue overflows, account suspensions, and media errors (in the case of MMS). Select the info icon to view the Twilio error code.
• Sent – Twilio has not received updated delivery information for your message. Typically, a sent status will be replaced by a delivered or undelivered status within seconds or minutes.
• Undelivered – Twilio has received a delivery receipt indicating that the message was not delivered. This can happen for a number of reasons including carrier content filtering, availability of the destination handset, etc. Select the info icon to view the Twilio error code.

To fetch notification history for a different number, enter a new Destination phone number and select Fetch SMS Notification History to refresh results.
