Which version of OpenCart module do I need?

Refresh the OpenCart cache when you have made changed, to activate them. Go to the modifications page and select the SendCloud module. Refreshing cache is done to click on the orange and blue button.
The error is shown as follows: 'SendCloudApiException' with message 'Authentication required'. On the next line: sendcloud_api.php on line 266
