Sends the HTTP PUT request to the server and then gets the content of the server response. It does not parse the HTTP response code and content of the server response.

It is not recommended to use this method to process large data (20 MB or 100,000 data rows can be considered as large data based on our tests).

Applies to

RESTClient object


objectname.SendPutRequest(string urlName, string data, ref string response)




The name of the RESTClient object from which you want to send the request.


A string value specifying the URL.


A string value specifying the data to send.

If the user sets the encoding charset in the Content-Type request header, this function will encode the data with the specified charset; if charset is not specified, this function will encode the data in UTF-8 by default.


The content of the server response.

If RESTClient failed to send request or server provides no response, the response value is an empty string. If the response value is compressed as gzip, it will be automatically decompressed. Only gzip compression format is supported at this moment. If the server specified the Content-Type response header, and in which the encoding charset is specified, this function will encode the data with the specified charset; if charset is not specified, this function will encode the data in UTF-8 by default.

Return value

Integer. Returns 1 if the function succeeds and a negative value if an error occurs. If any argument's value is null, the method returns null.

1 -- Success

-1 -- General error

-2 -- Invalid URL

-3 -- Cannot connect to the Internet

-4 -- Timeout

-7 -- Failed to decompress data

-10 -- The token is invalid or has expired

-14 -- Code conversion failed

-15 -- Unsupported character set


The following example updates the value of Department Name for the current row via SendPutRequest.
