Hi, I'm new to node red.  
I want to get an RGB value from colour picker with a 'HTTP in' and a 'HTTP response'.  
I made the following flow:

 ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/0/0/0024c3dae5ef37faed935d601e3b439c5d85d12a.png)  
The 'change' node is set as follows  
 ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/0/3/03fac4f4c07d6988d0ac5b22373ad42c0be8a7dc.png)  
So when I change the value with the colour picker:  
I get the value stored in 'flow'  
But when I start the GET from my browser or my STM32, I get empty {}  
After the operation, the flow is also empty:  
I tried looking in the forum, but I couldn't find the right way to do it (probably my question is mach to easy).

Thanks in advance!

Separate the flows as payload from httpin will be saved to.  
e.g.

```auto
