Tugger's Report Credentials (image below) contains all the details required for importing your data. You will require the Odata URL and Authentication Details' Username and Password when in Tableau.
Unless you have a specific need, there is no requirement to download the Power BI Report template for Tableau’s usage.
The example: the image below, shows a Teams connector, but other than having 'microsoftteams' in the URL link name, the other connectors will be the same with only the URL differing slightly.
After opening Tableau, you will be presented with a screen similar to the one shown below.
Select OData, as shown below.
If it is not shown, find it by clicking on More, under 'To a Server' as indicated below.
… Then select 'OData'
After selecting Odata, the following dialogue will appear
From Tugger, copy the OData Url, which is Harvest in the example (using the handy copy tool - as below).
Paste it into the Server field of the OData dialogue. Then, under Authentication, make sure 'Username and Password' is selected as in the following image.
... Then copy and paste the Username and Password from Tugger into the Odata fields indicated in the next image.
Click on Sign-In shown in the image below,
... and a dialogue appears as indicated in the following image.
After what is normally just a few seconds, all the datasets will become available; see below.
You will need to add the tables you require in the Data Source tab, and when linking them reference the Tugger Key ID, as indicated in the next image.
And as you can see in the next image (Sheet 1, which is highlighted) displays what was selected in the previous image and are now available to use.
This concludes the Tableau guide.
