    If a file or folder is renamed, the new entry will have the same 'id' as the previous (non-deleted) entry.

    So, if you want to keep track of renames, you should keep the existing state, from the previous /2/files/list_folder and /2/files/list_folder/continue calls.

    Here's a more complete example:

    curl -X POST https://api.dropboxapi.com/2/files/create_folder_v2 \
    --header "Authorization: Bearer <ACCESS_TOKEN>" \
    --header "Content-Type: application/json" \

#   "metadata": {
#     "name": "test_325818",
#     "path_lower": "/test/test_325818",
#     "path_display": "/Test/test_325818",
#     "id": "id:25N5ksooX-sAAAAAAAM5zg"
#   }
# }

curl -X POST https://content.dropboxapi.com/2/files/upload \
    --header "Authorization: Bearer <ACCESS_TOKEN>" \
    --header "Dropbox-API-Arg: {\"path\": \"/test/test_325818/test_325818.txt\"}" \

Yes, but this is not ideal when dealing with dropbox webhooks. Currently, when a rename action happens on a parent directory and Dropbox send us the change made by user. It do not add IDs to deleted entries. I wish there is a simple approach to handle this.
