In this code, you're still putting the access token on the URL, but additionally with the string "Authorization". You should instead be sending this as a header. Based on the rest of your code, for your client that would probably look something like this:

oHTTP:setRequestHeader("Authorization", "Bearer" + ctoken)

Likewise, note that for /2/files/upload, the API call parameters (your cJSON), should go in a "Dropbox-API-Arg" header, and the file data to upload should go in the request body. Please refer to the /2/files/upload documentation for more information on how to properly format this API call.

Thank You SIr

But Couldn't understand the issue please check my code and rectfiy the code where am wrong .

function main()

oHTTP:OPEN("POST", url , .F.)
oHTTP:setRequestHeader("Authorization: Bearer " + ctoken)
oHTTP:setRequestHeader("Dropbox-API-Arg:")
oHTTP:setRequestHeader("Content-Type", "application/octet-stream")

We're happy to help with any questions or issues you might have about the Dropbox API itself, but we can't debug or write code for you, especially when you're using a client not made or supported by Dropbox (in this case, oHTTP). You'll need to refer to the Dropbox API documentation for information on what formats and parameters to use when calling the Dropbox API, and then write the code for your library/platform accordingly. I also recommend referring to the documentation for your library/platform as a reference for how to construct the HTTPS requests as needed.

Looking at your latest code though, a few more things I notice:

• Your cJSON begins with '{c:\tmp\pdf\CKF1907319.pdf,', but per the /2/files/upload interface, that should be more like: '{"path": "/CKF1907319.pdf",'. That's supposed to be the path on Dropbox where you want to put the uploaded file.
• You're not actually setting anything in the "Dropbox-API-Arg" header. That should be set with your API call parameters, which you have in cJSON.
• I don't see where you actually send the file data to upload in the request body. Perhaps that should be done in oHTTP:SEND?

Hello Sir 

Could Not able to  Understand what to pass the values in cJson  and dropbox-Api-Arg    i am getting some errors please help me to solve this issue

 oHttp:setRequestHeader( "Dropbox-API-Arg", '{ "path": "' + cPath + '", "mode" : "add" }' )

Thanks & Regard

The value you pass in the "Dropbox-API-Arg" header should be a JSON string containing the parameters you want to use for the /2/files/upload call. You can find information on each of the parameters here:

https://www.dropbox.com/developers/documentation/http/documentation#files-upload

I do recommend using a JSON library to build your JSON string instead of trying to construct it manually.

The API v2 Explorer may also be a useful tool for prototyping calls and seeing what they would look like:
