Send data to Tago CORE

Send data to Tago CORE

Hi, I try to test Tago CORE.

On my computer I have Tago CORE in docker container with sqlite.
I create new device, copy Device Token and... how I can send data from device to TagoCORE using cURL?
I see this video: https://www.youtube.com/watch?v=5QjV3PaLgYc&ab_channel=TagoIO but here they moreover using RabitMQ. I try do it directly, but how to do it?
There is documentation for Tago.io: https://api.docs.tago.io/#41e953a9-8b0c-4166-aa0f-1db3596b02f7
But where is similar docs for Tago CORE?

I try do this like from documentation for Tago.IO but if I try execute this command:
```
curl --request POST \
  --header 'Content-Type: application/json' \
  --header 'device-token: 5407fe7e-d222-4993-84a0-b30dd5820222' \
  --data '{"variable":"a", "value":444}'
```
response is:
```
