Delivery reports

The REST API uses message statuses and error codes in delivery reports, which refer to the state of the SMS batch and can be present in either Retrieve a delivery report or sent to a callback.

Delivery report statuses

The status field describes which state a particular message is in. Note that statuses of type Intermediate will only be reported if you request a status per recipient (Retrieve a recipient delivery report), no callback will be made to report them.

The following statuses are available when using the SMS REST API:

Status Type Description
Queued Intermediate Message is queued within REST API system and will be dispatched according to the rate of the account.
Dispatched Intermediate Message has been dispatched and accepted for delivery by the SMSC.
Aborted Final Message was aborted before reaching the SMSC.
Rejected Final Message was rejected by the SMSC.
Deleted Final Message has been deleted. Message was deleted by a remote SMSC. This may happen if the destination is an invalid MSISDN or opted out subscriber.
Delivered Final Message has been delivered.
Failed Final Message failed to be delivered.
Expired Final Message expired before delivery to the SMSC. This may happen if the expiry time for the message was very short.
Unknown Final Message was delivered to the SMSC but no Delivery Receipt has been received or a Delivery Receipt that couldn't be interpreted was received.

Delivery report error codes

The delivery report status code provides a more detailed view of what happened with a message. The REST API shares most of its error codes with other SMS services.

In addition to these standard error codes, the REST API provides an additional set of error codes, all within the 4xx range (vendor specific errors in the range of 0x400 to 0x4FF as referenced in the SMPP specification). These are listed below:

Status Code (Hex) Name Status Description
400 Queued Queued Message is queued within REST API system and will be dispatched according to the rate of the account.
401 Dispatched Dispatched Message has been dispatched to SMSC.
402 Message unroutable Aborted SMSC rejected message. Retrying is likely to cause the same error.
403 Internal error Aborted An unexpected error caused the message to fail.
404 Temporary delivery failure Aborted Message failed because of temporary delivery failure. Message can be retried.
405 Unmatched Parameter Aborted One or more parameters in the message body has no mapping for this recipient. See Parameterization
406 Internal Expiry Aborted Message was expired before reaching SMSC. This may happen if the expiry time for the message was very short.
407 Canceled Aborted Message was canceled by user before reaching SMSC.
408 Internal Reject Aborted SMSC rejected the message. Retrying is likely to cause the same error.
410 Unmatched default originator Aborted No default originator exists/configured for this recipient when sending message without originator.
411 Exceeded parts limit Aborted Message failed as the number of message parts exceeds the defined max number of message parts.
412 Unprovisioned region Aborted SMSC rejected the message. The account hasn't been provisioned for this region.
413 Blocked Aborted The account is blocked. Reach out to support for help. Potentially out credits.
