 =====Send texts to mobile=====
+This application note describes a way to send text messages (SMS) from blocks via a SMS gateway service. It can serve as a boilerplate for anyone that wants to develop a similar script for some other SMS gateway service, or simply just needs the functionality and is happy to use the https://46elks.com/ gateway service from this app note as is.
+===== Installation =====
+You need a computer with a running blocks server with internet access and a web browser to test this application note.
+We have prepared a PIXILAB-blocks-root folder containing everything you need to run the example.
+{{ :blocks:app-note:sms42elks:smsgateway46elks.zip |Download this ZIP file and unpack it}}. If you do not know how to do this, read the instructions in the [[blocks:app-note:start|general setup section]].
+====Getting your Credentials====
+Goto [[https://46elks.com/]] and register an account and fill the account with some credits. Follow the vendors documentation to obtain a user token and a secret token (password).
+====Configuring the User Script====
+Before we can send a text we must apply our credentials obtained in the previous step. They can be set as properties from a task. This must be done before attempting to send texts.

+In production environment one may instead store the credentials more securely in a file on the server. The script looks for the file script/files/SMS_46elks.json, expected to be a JSON file with contents like this (but with your credentials, of course):
+<code>
+{
+  "user": "u2c8cde7b8f7951bbc18124cf4XXXXXX",
+  "password": "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
+}
+</code>
+====Send a text message from a task====
+Use a task to send a message, the phone number must include the country code, as shown in this example.
+{{:blocks:app-note:sms42elks:screenshot_2025-05-22_094859.png?800|}}
+Aternatively, call this function from a another user script, e.g. if your building a [[blocks:advanced_scripting:visitor_identity_tracking|Personal Visitor Experience]].
+====Result====
+A text message should be received.

+If not, check your log file for any error messages related to the SMS service, such as incorrect credentials.
