GitHub user bipasaroy10 created a discussion: 401 "unable to verify user
credentials and/or request signature" when calling deleteAutoScaleVmGroup
## Environment
- **CloudStack Version:** 4.22
- **API Response Format:** JSON
- **Client:** Node.js (custom API client using HMAC-SHA1 request
signing)
## Problem
I am able to successfully call several CloudStack APIs using the same
API key, secret key, and signing implementation. For example:
- `listAutoScaleVmGroups` ✅
- Other read APIs ✅
However, when I call `deleteAutoScaleVmGroup`, CloudStack consistently
returns the following response:
``` json
{
"success": false,
"message": "unable to verify user credentials and/or request signature",
"errors": {
"errorresponse": {
"errorcode": 401,
"errortext": "unable to verify user credentials and/or request signature"
}
}
}
```
## What I have verified
- The API key and secret key are correct.
- The same signing logic works for other CloudStack APIs.
- The request is signed immediately before being sent.
- The AutoScale VM Group ID exists and was obtained using
`listAutoScaleVmGroups`.
- The `id` parameter is being passed correctly from the application.
## Delete Request
The request is sent using:
``` text
command=deleteAutoScaleVmGroup
id=<autoscale_vm_group_id>
response=json
```
The request is signed using the same helper method that successfully
signs other CloudStack API requests.
## Expected Behavior
The AutoScale VM Group should either be deleted successfully or return
an error related to the resource (if applicable), instead of failing
during signature verification.
## Actual Behavior
CloudStack returns:
``` text
401 - unable to verify user credentials and/or request signature
```
even though the same credentials and signing implementation work for
other API commands.
Any guidance would be greatly appreciated. Thank you!
