Start 8x8 Matrix - with json

[Friedhofsblond]

Hello,
I would like to start my 8x8 matrix with a json file.

{"on":true,"bri":4,"seg":{"id":0,"i":[0,2,"4ffffd",2,6,"f9fe1b",6,9,"4ffffd","f9fe1b",10,14,"000000","f9fe1b","4ffffd",16,18,"f9fe1b",18,22,"000000",22,24,"f9fe1b","4ffffd",25,31,"000000",31,33,"4ffffd",33,39,"000000",39,41,"4ffffd",41,47,"000000",47,49,"4ffffd",49,55,"000000",55,57,"4ffffd",57,63,"000000","4ffffd"]}}

Sorry - I have no idea
What can I do?

Vielen Dank

versuchs mal damit
IP = deine IP des controllers

curl -X POST "http://IP/json/state" -d '{"on":true,"bri":4,"seg":{"id":0,"i":[0,2,"4ffffd",2,6,"f9fe1b",6,9,"4ffffd","f9fe1b",10,14,"000000","f9fe1b","4ffffd",16,18,"f9fe1b",18,22,"000000",22,24,"f9fe1b","4ffffd",25,31,"000000",31,33,"4ffffd",33,39,"000000",39,41,"4ffffd",41,47,"000000",47,49,"4ffffd",49,55,"000000",55,57,"4ffffd",57,63,"000000","4ffffd"]}} -H "Content-Type: application/json"

Hallo,
ja Danke habe dann hier im Forum doch noch was gefunden:

How do I send JASON API commands from Node red?

Newbie, with a noob question here. I saw in the WLED documentation that commands can be send to set colors individually to each LED using the JSON API To set individual LEDs starting from the beginning, use an array of Color arrays. {"seg":{"i":[[255,0,0], [0,255,0], [0,0,255]]}} will set the first LED red, the second green and the third blue. Now, how can I send this commands from Node Red? My idea is to write a “function” node that create custom effects but I don’t know how to send those…
