Send SMS Gateway API – ASP

This command can be used to send text messages to either individual numbers or entire contact groups.

Sample Request

Caution: Some users opt to place their request inside a code loop, while testing we highly recommend setting the test parameter to true , as occasionally an infinite loop can occur and users can consume all their credits very quickly.


sender If you have a promotional account, do not send this parameter. If you have a transactional account, use this field to specify the sender name for your message. Sender name must be 6 alpha characters and should be pre-approved by Textlocal. In the absence of approved sender names, use the default 'TXTLCL'
message The message content. This parameter should be no longer than 766 characters. See Helpful Information for message length details. The message also must be URL Encoded to support symbols like &.
Login Parameters (Additional Information)
username The email address used to log into Textlocal.
hash Your secure hash can be found within Messenger in the main navigation under "Help->All Documentation". Alternatively you can use the password parameter instead and use your Textlocal password in plain text.
Optional Parameters
apiKey This can be used instead of the username/hash/password. You can create them in your Messenger Control Panel (click here) for each application, and limit the usage of them by host IP Address.
numbers Comma-delimited list of mobile numbers in international format (i.e. 918123456789).
group_id This parameter can be used in place of the numbers parameter in order to send to an entire contact group. This parameter should contain the ID of the relevant group, which can found either within Messenger (in the "Reports" - "Advanced Reports" - "List of Group ID's" section) or by running the get_groups command. Additionally group 5 contains "contacts" and group 6 contains "opt-outs".
schedule_time This parameter can be used to specify a schedule date/time for your message, which should be provided in Unix timestamp format. Times should be provided in GMT.
receipt_url Use this field to specify an alternative URL to which the delivery receipt(s) will be sent. See handling receipts documentation.
custom This value will be set against the message batch and will passed back in the delivery receipts. This allows you to match delivery receipts to their corresponding messages.
optouts Can be set to true in order to check against your own opt-outs list and Textlocal's global opt-outs database. Your message will not be sent to numbers within these lists. If not provided defaults to false.
unicode Set this value to true to specify that your message body will contain unicode characters. See Encoding/Decoding Unicode Documentation
test Set this field to true to enable test mode, no messages will be sent and your credit balance will be unaffected. If not provided defaults to false
Note: While both numbers and group_id are optional parameters, one or the other must be included in the request for the message to be sent.
