Using ETL tool's REST utility to download a folder with REST get URL

For reference, this is a Core API a.k.a. API v1 endpoint, documented here:

https://www.dropbox.com/developers-v1/core/docs#files_put

API v1 supports both OAuth 1 and OAuth 2 for authentication, with OAuth 2 being preferred. When you make an API call, the OAuth access token you supply with it identifies the relevant account.

To specify the path you want to upload to in that account, you put the path on the URL (where the <path> placeholder is shown). This should be the entire path, including any parent folders, as well as the desired filename. E.g., to upload a file as test.txt inside a "Documents" folder in root, the path would be: "/Documents/test.txt".

Yes, you can use generated access tokens there. OAuth 2 access tokens generated via the App Console work the same as OAuth 2 access tokens retrieved via the OAuth flow (i.e., /oauth2/authorize and /oauth2/token). The only difference is that you can only generate an access token for your own account, whereas the OAuth flow can be used for any account.

For API v1, you can send these parameters as URL parameters, or form encoded in the body. For example, either of these are valid:

curl -X "POST" "https://api.dropboxapi.com/1/fileops/copy" \
 -H "Authorization: Bearer <ACCESS_TOKEN>" \
 --data "root=auto&from_path=/test.txt&to_path=/test_new.txt"

or

curl -X "POST" "https://api.dropboxapi.com/1/fileops/copy?root=auto&from_path=/test.txt&to_path=/test_new.txt" \
 -H "Authorization: Bearer <ACCESS_TOKEN>"

(Perhaps you looked at some API v2 documentation at some point? API v2 does take JSON in the body. We generally would recommend using API v2 instead of API v1, if it has all of the functionality you need anyway.)

Thanks, I was trying to use dropbox/foldername or home/foldername and was getting 404. Now it is working fine! 

One more question or confirmation, this is the path I followed:

1. Created a new app

2. used the link to allow access to App and generate the authorization code:

https://www.dropbox.com/1/oauth2/authorize?client_id=<YOUR-APP-KEY>&response_type=code

3. then using the below command generated the authorization token for use in the header of the HTTP Request:

curl https://api.dropbox.com/1/oauth2/token -d grant_type=authorization_code -d code=<YOUR-AUTHORIZATION-CODE> -u <YOUR-APP-KEY>:<YOUR-APP-SECRET>

My question is  - can we generate the token using the GENERATE button in the OAuth2 section of MyApp and used it as Authorization: Bearer <token> in the header?

Please advise.

Is there a way to download all the files in the folder? When I just end my URL at the folder name, it gives me 404 error.

Or is there a way to user regular expressions in the URL?

The Dropbox API doesn't offer a way to download an entire folder at once, or files in bulk, so you'll need to iterate through the specific files you want to download. I'll be sure to pass this along as a feature request though.

I am trying to copy a file from one folder to another, but I am getting a 400 error and it does not state what is the error. my payload is like this :

{
"root": "auto"
"from_path": "jobViteTest/file.csv"
"to_path": "jobViteTest/archive/new_file.csv"
}

where both from and to paths are existing but I want to copy and rename the file file.csv to new_file.csv. Can you please advise.

The body of the response for the API call will contain more information. Please print that out in order to see what the issue is.

I tried to execute this time using POSTMAN as the tool I am using does not print the response. First Postman was not able to complete OAuth 2.0 authorization when I tried to generate the token. Nonetheless, I used the callback api and put it in the settings page and used the generated token. Then it gave me this error:

{
"error": "Must send either a from_path or a from_copy_ref"
}

I was giving parameters like root, from_path, to_path in the Body as JSON. I even tried to pass these parameters as headers, but still the same error.
