Hello everyone,
I'm new on Node-red and I'm struggling for now 1 week on a simple problem.
To quickly sum up my situation, I'm sending data through an HTTP POST like this:
The thing is that I need to retrieve my data from the HEX packet of my payload, and not from the text interpretation. For example, here my data is **02 98 cb d8 00 15 2b 02 0f 80 23**. But I'm not able to retrieve it, since node-red is always interpreting my **02 98 cb d8 00 15 2b 02 0f 80 23** as a string when it arrive on Node-Red.
For example, **02 98 cb d8 00 15 2b 02 0f 80 23** is interpreted as follow:
And when I try to pass it in a buffer it give me **02 ef bf bd ef bf bd ef bf bd 00 15 2b 02 0f ef bf bd 23** instead of **02 98 cb d8 00 15 2 b 02 0f 80 23**.
to conclude, I'm not able to get my "true" data at the moment.
So, do you guys have any idea about how to proceed to get the binary/raw data from the post ?
Thanks you in advance,
Regards,
Cédric R

Hi, by the sounds of it, you are in control of what is being sent - so what does the byte data actually represent?
for example, assuming the data is 2xUINT32s, 1xUINT16 and 1xbyte (i am guessing) why not simply send JSON
e.g. `{"item1":3637221378,"item2":36377856,"item3":32783,"item4":35}`
then the values of the payload can be easily used in your flow as a native JS object.
If instead you insist of sending binary data, you could convert it to base64 (`"ApjL2AAVKwIPgCM="`) in your sending application and use the base64 node to convert it back to a buffer in node-red.

Hi, thanks for your answer.
It's not that simple, I would want to retrieve the data **02 98 cb d8 00 15 2 b 02 0f 80 23** to resend it in a new formed HTTP packet.
At the end, I use an HTTP request to send a JSON payload to another server, like:
```auto
{
"deviceid": "abcde",
"value": "02 98 cb d8 00 15 2 b 02 0f 80 23", // NB: or the base64 value, nvm
"devicetype": "SomeSensor"
}
```
So it's like if I was using node-red as an HTTP to HTTP proxy where I'm doing some treatment on my payload. And to do it I need to be able to retrieve the "raw payload".
All the work to achieve is about this hex payload "hidden" in the packet .. 😕

It doesn't look like you are setting the `content-type` header on the request. Without that header, NR has to guess at the type of content being sent and, in this case, is incorrectly interpreting it as a string.
If you can set the `content-type` to `application/octet-stream` then NR will know to treat it as the raw bytes and pass it on as a Buffer object.

Thanks for your answer, I'll try this !

It's now working with the header `content-type: application/octet-stream`
Thank you so much !!
