Hello good folks,
I am trying to upload multiple files at once, from Node-RED to another server, using the _HTTP Request_ Node. The documentation explains the payload structure required to attach a single file:
```auto
{
"KEY": {
"value": FILE_CONTENTS,
"options": {
"filename": "FILENAME"
}
}
}
```
This works when I need to upload a single file, but what about multiple files?
Here's the architecture of my system:
- **SERVER 1** submits, through a single HTTP request, one or more files to Node-RED
- Node-RED captures these files with the _HTTP In_ node and forwards them to **SERVER 2** using the HTTP Request node. All files must be embedded into that single HTTP Request.
- **SERVER 2** processes the files and responds with a summary of the processing information to Node-Red
- Node-RED then simply sends back the response to **SERVER 1**
I unfortunately have no control over either **SERVER 1** or **SERVER 2** , so I cannot change the way they send/process files.
So in summary, I need all files received as a group to be forwarded as a group to the destination server so it can aggregate data pulled from all attachments it receives in a single transaction.
Judging from the JSON structure above, this isn't possible. Are there alternatives to the HTTP Request node for this specific use case?
Thanks

Well it looks like I answered my own question after digging through the code for the HTTP Request node: there can be as many "KEY" properties as you want in the payload structure:
```auto
{
"File1": {
"value": "some file content",
"options": {
"filename": "MyFirstFile.txt"
}
},
"File2": {
"value": "some other content",
"options": {
"filename": "MySecondFile.txt"
}
}
}
```
I personally think it would have been more explicit if the payload contained an array instead of distinct properties, but hey, what do I know?!? 🙂
