The 1NCE SMS Forwarding Service provides different types HTTP messages for Mobile Originated (MO) and Mobile Terminated (MT) SMS. In the following sections, the message events for MO-SMS and MT-SMS are outlined and an example JSON message is shown as reference.

MO-SMS

Normal Mobile Originated SMS messages issued from devices with a 1NCE SIM are forwarded to the specified HTTP endpoint as JSON objects in a fixed format. The JSON message body contains parameter field which specify the payload and additional configurations. Listed below is an overview of these values from the HTTP Post Body of a MO-SMS message.

Property	Data Type	Description
`id`	INTEGER	Unique ID of the SMS message.
`payload`	STRING	SMS message payload. The format (Alphabet Text, Binary Data, etc.) depends on the set Data Coding Scheme (DCS) value.
`submit_date`	STRING	Timestamp of when the SMS message was send by the mobile device.
`destination_address`	STRING	Phone number specified by sending party as destination. This parameter is ignored by the 1NCE SMS Service.
`source_address`	STRING	MSISDN of the SIM card that send the SMS message. The MSISDN is the phone number of the SIM.
`dcs`	INTEGER	The Data Coding Scheme (DCS) is a value which transports information about how the recipient device shall handle the the transferred data payload.
`endpoint`	JSON OBJECT	Details about the originating SIM. The Name lists the ICCID of the SIM.
`organisiation`	JSON OBJECT	Contains the internal organisation ID, not to be confused with the 1NCE organisation ID.
`multi_part_info`	JSON OBJECT	Information about multi-part SMS messages. The parameters list the current part number and the total amount of messages in the concatenated message.

A JSON object with the listed parameters will be send with a HTTP Post request towards the specified customer endpoint for the SMS Forwarding Service. Below an example of such a JSON message is shown.

{
	"id": 6202,
	"payload": "message text",
	"submit_date": "2018-08-17 16:31:51",
	"dest_address": "12345",
	"source_address": "<msisdn>",
	"dcs": 0,
	"endpoint": {
		"id": 8765412,
		"name": "<iccid>"
	},
	"organisation": {
		"id": 4567
	},
	"multi_part_info": {
		"partno": 1,
		"total": 1,
		"identifier": 6202
	},
	"pid": 0
}

MT-SMS

For Mobile Terminated SMS where the message is send towards a SIM device, the SMS Forwarding Service is not forwarding the actual SMS message itself to the application server. Instead, only the Delivery Report (DLR) of the MT-SMS is sent via the Forwarding Service.
The DLR indicates the successful delivery of the MT-SMS using a 1NCE SIM card. When a MT-SMS is sent to a device via the 1NCE Portal or the 1NCE API, the SMS Forwarding Service provides a Delivery Report (DLR) in a JSON format. Below, the parameters of the HTTP Patch Body from the DLR message are explained.

Property	Data Type	Description
`id`	INTEGER	Unique ID of the DLR message.
`final_date`	STRING	Timestamp when the MT-SMS was finalized by the receiving SIM device.
`submit_date`	STRING	Timestamp when the MT-SMS was originally issued.
`organisation`	JSON OBJECT	Contains the internal organisation ID, not to be confused with the 1NCE organisation ID.
`endpoint`	JSON OBJECT	Details about the originating SIM. The Name lists the ICCID of the SIM.
`status`	JSON OBJECT	Indication of the delivery status of the MT-SMS. The DLR response could be DELIVERED or FAILED when the MT-SMS was not successfully transmitted.

In contrast to the MO-SMS, the JSON object for the DLR of the MT-SMS will be send with a HTTP Patch request towards the specified customer endpoint. Below an example of such a JSON message is shown.

{
	"id": 2819195,
	"final_date": "2020-06-09 15:06:38",
	"submit_date": "2020-06-09 15:06:34",
	"organisation": {
		"id": 4567
	},
	"endpoint": {
		"name": "<iccid>",
		"id": 8765432
	},
	"status": {
		"id": 4,
		"status": "DELIVERED"
	}
}
