wordpress sms plugin for joaoapps' Join Android app

Please see attachments for more readable description. I use the Join Android app from joaoapps, it allows me to send text messages from multiple devices, it also provides an API allowing me to execute the following command: curl -k "[login to view URL]" Where: %num% is the destination cell phone # %msg1% is the first text message I want to send %deviceid% is a 32 character device identifier %apikey% is a 32 character api key If I want to send three text messages, I issue three curl commands: curl -k [login to view URL] curl -k [login to view URL] curl -k [login to view URL] where msg1 is message 1, msg2 is message 2, msg3 is message 3 I want a WordPress Plugin developed so that by going to [login to view URL] I am presented with a text box to enter a destination # and an option to send one of two predefined sets of messages (remember each set may be three lines or messages), or to enter a text message into a text box. If I am logged into the WordPress user (via [login to view URL]) or if my IP address is whitelisted, I am permitted to enter. If not, I am blocked and returned to [login to view URL] The Plugin settings should include: - Text box for white-listed IP addresses entered in comma delited fashion, allowing for subnet mask, for example: [login to view URL],8.8.8.0/24,4.4.4.1 - Two text boxes for the predefined multi-line/message sets of text messages - Text box for device identifier - Text box for api key The plugin should be delivered in a zip file suitable for installing on a WordPress 5.1.1 website running PHP 7.2 I currently accomplish this task by running a Windows batch file, I want to web enable this for the benefit of others in my organization and intend to release it to the joaoapps community for their use. The batch file reads as follows (I have changed the device & API keys and truncated the messages for readability): set num=630-665-7898 set deviceid=5530a12345f54793aec1bd1234567890 set apikey=0312345d327744e0980c4d1234567890 set msg1=Katy%%20Computer%%20is%%20near%%20St%%20Luke's,%%20on%%20Woods%%20Mill%%20[login to view URL] set msg2=From%%20I-64,%%20go%%20North%%20on%%20141 set msg3=Come%%20in%%20the%%20lower%%20level%%20of%%20the%%20building curl -k "[login to view URL]" curl -k "[login to view URL]" curl -k "[login to view URL]"
