Send SMS Landing

With this method you can send bulk SMS Landing easily. This method has been extremely optimized to send more than 500.000 SMS in less than one hour.

To send SMS Landing via API, you must first have it created in your account in your user panel, since you will need `landing_id` to send it.

Request

api_key Your API Key.
messages Array of messages you want to send.
from Originator address (sender). Up to 15 numeric or 11 alphanumeric characters. All characters non-ASCII will be replaced with its equivalent if exist any (á => a), empty in another case.
to Destination mobile number in international format. Country code must be included.Ex: to=447525812121 when sending to UK.
text Body of the text message including the tag {LANDING} (with a maximum length of 459 characters). Ex: "Déjà vu, you can find it and more in our shop: {LANDING}"
custom Include any reference string for your reference. Useful for your internal reports. Maximum 32 alphanumeric characters.
send_at When this message should be sent as timestamp in YYYY-MM-DD HH:MM:SS format. If you specify a time in the past, the message will be sent immediately.
landing_id ID of the landing template created in your account.
campaign_name Name of the campaign in case your want to group more than one SMS in a unique campaign to see it in your panel (otherway no one campaign will be created).
report_url URL where you want to receive the delivery report (DLR) and the events of the landing as your client open it or click in some link or action.
concat Set to 1 if you want to allow concatenated messages (more than 160 characters). If concat is 0 (or it's not present) only first 160 chars will be sent.
encoding Set to UCS2 if you want to send messages UCS2 (70 Unicode characters per SMS) with accents, emoticons and special characters. If encoding is GSM7 (or it's not present) the SMS will be treated as GSM7 (160 non Unicode characters per SMS). The Unicode encoding is only applicable to the text of message.
fake Set to 1 if you want to simulate submitting messages, it's perfect for testing and debugging, it has no cost.

Errors

Error ID Explanation
INVALID_CONTENT_TYPE The content type must be: Content-Type: application/json
JSON_PARSE_ERROR Your JSON was formatted incorrectly or was considered otherwise improper or incomplete. Check it here.
MISSING_PARAMS Your request is incomplete and missing some mandatory parameters.
BAD_PARAMS One or more of your parameters has incorrect format or value.
UNAUTHORIZED Your API key may be invalid, double-check that your API key was input correctly or see if the IP is blocked in your account API settings.
INVALID_LANDING The `landing_id` you have selected it's incorrect. Check the correct landing ID inside your panel in the templates section.
INVALID_SENDER The sender address (from parameter) was not allowed for this message.
INVALID_DESTINATION Our Gateway was unable to process your destination. The number must be in MSISDN format. Check format here.
INVALID_TEXT The field was empty or is corrupt.
INVALID_DATETIME The format we were expecting was: YYYY-MM-DD HH:MM:SS
NOT_ENOUGH_BALANCE Your account has no funds to process this request, add credits to your account and try again.
LIMIT_EXCEEDED Your request has exceeded the maximum of 1000 sms requests per batch.

Special long characters

There are 9 special characters that are counted as 2 individual characters when GSM encoded. This could result in a message becoming longer and therefore being concatenated.The following table identifies these characters.

Concatenated GSM messages

Also referred to as a long message, multipart message or extended message, a concatenated message is formed from several standard SMS containing a 7 byte concatenation header at the beginning of each one. Since this 7 byte header is within the message, it reduces the total size of each SMS to 153 characters each. The table below shows the maximum message length per number of SMS used for plain 7-bit messages. If you want to send a concatenated message, don’t forget you must set the parameter "concat" to value 1.

Number of SMS Maximum Message Length
1 160 characters.
2 306 characters.
3 459 characters.
4 612 characters.
5 765 characters.
6 918 characters.
7 1071 characters.
8 1224 characters.

GSM Enconding

According to GSM specification, a standard SMS message can contain up to 140 bytes of data (payload). Standard latin (ISO-8859-1) character encoding represents a single character using 1 byte, which is 8 bits. Therefore, the maximum number of latin 1 characters that could be included in an sms is 140.

GSM encoding represents characters using 7 bits instead of 8. This therefore provides a maximum of 160 characters per SMS. (140 * 8 bits) / 7 bits = 160

This effectively halves the number of characters that the GSM character set can support, compared to ISO-8859-1. In order to include common characters that are usually represented using the 8th bit, these characters as well as other symbol characters must be re-mapped to a combination of lower bits. These re-mapped characters are often referred to as special characters. This re-mapping, in combination with packing 7-bit characters into 8- bit bytes is called GSM Encoding.

UCS2 Encoding

UCS2 is the Unicode format required for SMS, as opposed to the later format UTF-16. Since each UCS2 character requires 2 bytes, the SMS message length is reduced to 70 characters: 140 bytes / 2 bytes = 70 characters. You must also set the correct Data Coding Scheme value, 0 x 08 or 8 in the case of UCS2.

UCS2 encoding allows the use of emoticons in SMS and these are treated as characters so you can write it in your SMS as any other character.

Unicode messages can be concatenated. The concatenation headers reduce the characters available for content as follows:

Number of SMS Maximum Message Length
1 70 characters.
2 134 characters.
3 201 characters.
4 268 characters.
5 335 characters.
6 402 characters.
7 469 characters.
8 536 characters.
Once you have everything set up, try to send messages with weird characters like this one:
@$¥èeùìòÇØøÅå _ ^}{\[~]|EÆæßE!"#%&()*+,-./0123456789:;<=>?¡ABCDEFGHIJKLMNOPQRSTUVWXYZÄÖÑܧ¿abcdefghijklmnopqrstuvwxyzäöñüà

That's all!
