Hello, I recently completed a project that used the SIM800C and an STM32 micro to send a HTTP POST request when an input is triggered. This included both the PCB design and firmware. Please get in touch if you would like to discuss this further.

it is fairly simple to do, specially that is you already hook up the esp with the sim. so I can just play with the AT stuff I can also do this via teamview if you want I split it into 2 job 1. Recieving SMS command (what word you want to use to trigger the sending) 2. Sending command to api (GET / POST . JSON is possible) I am looking forward to hearing from you
