Blockspring for Tableau is a single Tableau Web Data Connector that lets you access all of the services on Blockspring.com that return tabular data from Tableau.
Step 1. Install Tableau Desktop 9.1+ if you don't yet have it.
Step 2. In Tableau, click Add data in the top navigation pane to connect to data.
Step 3. Choose "Web Data Connector".
Step 4. Copy "https://www.blockspring.com" into Tableau.
There is no data size limit, however any request for data must complete in 60 seconds. All requests longer than 60 seconds will timeout and return no data.
When you authenticate with a service (e.g. Google Analytics) on Blockspring, that key is encrypted and stored in your Blockspring account. Then, when Tableau makes the request for data, you don't have to re-sign in with all of the services your dashboard is built on, you just sign in with Blockspring.
