| to | Phone number of the received. Plus signs (+) must be URL encoded | [M] | |
| text | Contents of the message, URL encoded as necessary. | String | [M] |
| charset | Charset of text message. Used to convert to a format suitable for 7-bit or UCS2. Defaults to ISO-8859-1 if coding is 7-bit and UTF16BE if coding is UCS2 |
String | [O] |
| udh | Optional User Data Header (UDH) part of the message. Must be URL encoded. | String | [O] |
| mclass | Sets the Message Class in DCS Field. Accepts values between 0 and 3. 0 = Sends the message directly to display 1 = Sends to mobile 2 = Sends to SIM 3 = Sends to SIM Toolkit | Number | [O] |
| mwi | Sets Message Waiting Indicator bits in the DCS field. If given, the message will be encoded as Message Waiting Indicator. The accepted values are 0, 1, 2, 3 for activating the voice, fax, e-mail and other indicator. Or 4, 5, 6, 7 for deactivating respectively. | Number | [O] |
| coding | Sets the coding scheme bits in DCS field. Accepts values between 0 and 2. 0 = 7-bit 1 = 8-bit 2 = UCS2 If unset, defaults to 7-bit unless a UDH is defined, which sets coding to 8-bit. | Number | [O] |

The value is a bit mask composed of: 1 = Delivered to phone 2 = Non-delivered to Phone 4 = Queued on SMSC 8 = Delivered to SMSC 16 = Non-delivered to SMSC. If you want multiple report types, you simply add the values together. For example, if you want to get delivery (1) and non-delivery (2) you set the dlr-mask value to 3 (1+2). If given, dlr-url must be given as well. | Number (bit mask) | [O] |
| dlr-url | If dlr-mask is given, this is the URL to be fetched. (Must be url-encoded) | String (url) | [O] |
| pid | Sets the PID value [2]. For example, a SIM Toolkit message would use something like the following: &pid=127&coding=2&alt-dcs=1&mclass=3 | Number | [O] |
| alt-dcs | If unset, 0X per default. 1= uses FX. 2 = force 0X | Number | [O] |
| id | A user provided identity of the message. If DLR is requested it will be possible to have this user provided identity included in the DLR-URL. Maximum length of this field is 32 bytes. | String | [O] |

Inbound SMS HTTP
Destination URI
To receive the MO message, Sinch needs a URL that specifies where the messages should be sent. The URL will be passed as HTTP1.1 GET request. Sinch needs:
- Hostname
- Port
- URL: Use escape codes when construct the URL
URL escape codes
| Escape codes | Description |
|---|---|
| %t | The time the message was sent, formatted as YYYY-MM-DD HH:MM. |
| %T | The time the message was sent, in UNIX epoch timestamp format. |
| %p | The MO number. |
| %P | The phone number of the sender. |
| %q | Like %p, but a leading 00 is replaced with +. |
| %Q | Like %P, but a leading 00 is replaced with +. |
| %A | The short message content. |
| %u | udh of incoming message. |
| %C1 | MCC + MNC of the sender for the SMS message. (Short codes only). |
Example
This URL will pass the MO message to the http server "mo.yourdomain.net" on tcp port 5000. The example script to receive and parse the request is "yourGetMo.php." Sinch will escape the destination MSISDN to variable "msisdn," originator address to variable "originator" and the message to variable "msg."
