The variable substitution format is ``. Here is a list of variables referred to in this tutorial. | Variable | Description | | ----------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------- | | `` | The hostname for the initial tenant created during account onboarding. Such as `tenantname.region.qlikcloud.com`. | | `` | A bearer token for authorizing `https` requests to the ``. For more information, see [Authentication](https://qlik.dev/authenticate). | | `` | An OAuth client ID for authorizing requests if using the platform SDK. | | `` | An OAuth client secret for authorizing requests if using the platform SDK. | | `` | The path on your local system to a data file, such as `/path/to/datafile.csv`. | | `` | The name that will be displayed for the uploaded data file, for example `mydatafile.csv`. | | `` | The ID of the shared space that the data file resides in. | | `` | The ID of the shared space that you wish to move the data file to. | | `` | The ID for the data file. | | `` | The ID for the user who you wish to transfer ownership of the data file to. | ## Update the data file To update a file in an existing data file asset, use the data file ID and pass the new file. Optionally, you can also update the data file metadata using these endpoints and calls. > **Note:** When updating some data file metadata, such as the filename, the corresponding data set is not automatically updated. > If your users use the Qlik Cloud hub to search for data, ensure you also update the data set. ```bash curl -L -X PUT "https:///api/v1/data-files/" ^ -H "Authorization: Bearer " ^ -H "Content-Type: application/json" ^ -H "Accept: application/json" ^ -F "file=@\"\"" ``` This multi-step process supports files up to your entitled limits in Qlik Cloud. Instead of uploading directly to the `data-files` API, you upload first to `temp-contents` using a chunked upload, and then import this file to `data-files`. If you are using Windows, you should update the line continuation character to `^`. ```bash # Upload data file to temp-contents, and capture temp-contents file id TEMP_CONT_ID=$(curl -L "https:///api/v1/temp-contents?filename=" -v \ -X POST \ -H "Authorization: Bearer " \ -H "Content-Type: application/octet-stream" \ -H "Transfer-Encoding: chunked" \ -T "" 2>&1 \ | grep -F "< location:" | awk '{print $3}' | tr -d '[:space:]' | awk -F / '{print $NF}') # Update data-file from temp-contents curl -L -X PUT "https:///api/v1/data-files/" \ -H "Authorization: Bearer " \ -F "json="{"tempContentFileId":"$TEMP_CONT_ID"}"" ``` If your file is larger than 500 MB in size, add `--resumable` to have qlik-cli automatically handle the upload of this file via `temp-contents`. ```bash qlik data-file update --file "" ``` If using qlik-cli, the response will look similar to:
Example qlik-cli response ```json { "id": "", "name": "", "size": 24743, "createdDate": "2023-03-23T11:26:20.631Z", "modifiedDate": "2023-04-28T15:41:19.8263046Z", "ownerId": "637390ec6541614d3a88d6c1" } ```
A `201` status code indicates the data file was updated successfully. ## Move a data file to a different space To move a data file to a different space, you need to know the file ID and the ID of the space you want to move the data file to. ```bash curl -L "https:///api/v1/data-files//actions/change-space" ^ -H "Authorization: Bearer " ^ -H "Content-Type: application/json" ^ -d "{\"spaceId\": \"\"}" ``` ```bash qlik data-file change-space --spaceId ``` A `204` response confirms that the ownership of the data file has been updated successfully. ## Move all data files in a space to a different space To move all data files to a different space, you need to know the space ID of the space the files currently reside in, and the space ID of the space to move them to. ```powershell # qlik-cli/powershell # Set the space ID of the space containing the data files to move $spaceId = ''; # Set the space ID of the space you wish to move the data files to $targetSpaceId = ''; $dataConnection = qlik data-file connection ls --spaceId $spaceId | ConvertFrom-Json $dataFiles = qlik data-file ls --connectionId $dataConnection.id --limit 1000 | ConvertFrom-Json $dataFileCount = $dataFiles.Length; $dataFileIter = 0; Write-Host "$dataFileCount data files found." foreach ($dataFile in $dataFiles) { $dataFileIter += 1; qlik data-file change-space $dataFile.id --spaceId $targetSpaceId; Write-Host "Moved data file $dataFileIter of $dataFileCount."; } ``` This snippet can be pasted into a Qlik Automate workspace. ```json {"blocks":[{"id":"D535528C-1A75-492E-949B-059B6B64B2B3","type":"VariableBlock","disabled":false,"name":"sourceSpaceName","displayName":"Variable -
