SMS Sent postbacks are sent when Esendex sends a message to the aggregator for delivery.

Type Properties

Property Name Description Data Type Sample

This is posted when we send a message to the aggregator for delivery. A value of 1 indicates success. A value of 0 indicates failure: the aggregator was not able to accept the message. Failure is most likely because the destination phone number is a landline. In case of failure, Esendex will retry the message automatically for a total of three times. After three failures, Esendex will cancel the message. Note that some upstream paths do allow text messages to go to a landline.
