GCS storage create folder API - google-cloud-storage

Question

Having trouble creating folder in a bucket in Google Cloud storage thru a API
I have already tried the curl call for the API with all varying possibilities for the request json format.
ABC is not really the organization but gave it to obfuscate real data. I have also setup the variable $access_token using gcloud call to get access-token.
curl -X POST -H "Content-Type: application/json" -H "Authorization: Bearer $access_token" -d '{"displayName":"[vicks]"}' https://cloudresourcemanager.googleapis.com/v2/folders?parent=ABC
{
"error": {
"code": 400,
"message": "field [Folder.display_name] has issue [invalid format]",
"status": "INVALID_ARGUMENT",
"details": [
{
"#type": "type.googleapis.com/google.rpc.BadRequest",
"fieldViolations": [
{
"field": "Folder.display_name",
"description": "invalid format"
}
]
}
]
}
}
I am expecting the API call to create the directory but it fails showing error in display_name format though I have followed the document at https://cloud.google.com/resource-manager/docs/creating-managing-folders

Unfortunately, the link you provided is about the API that will help you create a folder within your organization and not inside a Cloud Storage bucket. This can be seen by looking at the first graph in the page you linked.
Thankfully, there is still a solution that might help you achieve what you’re looking for. While Google Cloud Storage objects are stored in a flat namespace, tools like gsutil or the even the Google Cloud Console can provide a hierarchical view of the objects by following simple naming rules (it is essentially an emulation of subdirectories).
1) To treat an object as a directory, you can create an empty object that ends with “/”. If you want a subdirectory called ‘abc’ then you can call the object ‘abc/’ and gsutil will treat it like an empty directory. To insert an object/file into the subdirectory, you may simply copy an object/file to the destination URL including ‘abc’ such as “gs://your-bucket/abc”.
2) Another less commonly used way is to create an empty object that ends with “$folder$”. If you want a subdirectory called ‘abc’ then you can call the object ‘abc$folder$’ and gsutil will treat it like an empty directory. Similarly to the previous point, to insert an object/file into the subdirectory, you may simply copy an object/file to the destination URL including ‘abc’ such as “gs://your-bucket/abc”.
I would highly suggest you read through this link to get a great understanding of how Google Cloud Storage subdirectories work. Additionally, I’ve found another previously answered stack question that is very relevant to your question and can be of great help to you as well.
