Channel logs

For each message processed, you can view the following information, also known as message attributes:

• Direction: Indicates whether the message was outbound (sent by you) or inbound (sent to you by a customer).

• Status: Shows the message's location in the message lifecycle.

• Message ID: A unique identifier for the message.

• From: The identifier or number of the message sender and, when applicable, its country.

• To: The identifier or number of the message recipient and, when applicable, its country.

• Type: the type of message.

• Created at: The time the log was created.

• Updated at: The time the log was last updated.

• Failure Code: failure codes provide a standardized categorization of the root cause of a message failing.

Inspect log

To get more details about a specific message, click on it to open the Inspect log panel.

The Inspect log panel contains two tabs: the Latest and Interaction.

• The Latest tab displays information about the current message status and the raw message body.

• The Timeline tab shows the message history, including the timestamps of every status change.

Troubleshooting tips

Information about failures is provided hierarchically

• Statuses: indicate, at the most general level, if a message failed when delivering (delivery failed) or couldn't be sent (sending failed) in the first place

• Failures Codes and Sources: provide information on what system or entity (the source ) failed the message and why (the code), for example, 15002 : invalid permission indicate that the message could be delivered for lack of registration
• Failure Reasons: summarize in a human-friendly way all of the above, for example Details: sender unregistered; reason: carrier_rejected; code: 104 specifies the sender (from) of the message wasn't registered with the downstream SMS carrier

Looking at reasons is usually the easiest way to determine the failure cause of a specific message

Once this is found, filtering by failure codes and/or country. It should be an attempt to confirm that is the predominant failure reasons (in the example below, it is clear how 15002 affects multiple recipients, and the root cause is 30301 lack of registration in the USA)
