8/3/2023 0 Comments Tableau public api![]() At this point, you must be wondering why I have to use SQL Server to call ZappySys ODBC Driver? Why can’t I directly use ZappySys ODBC Driver in Tableau? Once REST API Data source is configured in ZappySys Data Gateway, we can move forward to creating Linked Server part. ![]() Once data source is tested and configured you can click Save button in the Gateway UI toolbar and click Yes for Restart Service.Generate Example Code for ZappySys Driver You can also read this article for other example of calling SQL Server Queries via ZappySys Data Gateway. Import API data in Tableau using Microsoft SQL Server Connector by calling Linked Server SQL QueriesĪssuming you have already done first step lets get started with remaining steps.Create Linked Server in Microsoft SQL Server and connect to ZappySys Data Gateway.Configure ZappySys Data Gateway (Create API connection) – We will see in depth, later in this article.Install ZappySys ODBC PowerPack (API Drivers).If you don’t have one you can always use lightweight FREE SQL Express Edition (Download). Make sure you have access to Microsoft SQL Server instance.To access REST API in tableau using SQL Server Connection, you have to perform the following high level steps. So if we use SQL Server to wrap those complex queries then it becomes much simpler because Tableau has very good support for SQL Server compared to 3rd party ODBC Drivers. JOIN Syntax, CAST functions, Sub queries). Now you must be wondering why use approach#2 and not #1 ? Tableau doesn’t play well when it comes to 3rd party ODBC drivers because behind the scene Tableau generate complex SQL statements which may not be supported by ODBC driver its trying to call (e.g. We recommend Approach#2 for any ZappySys driver use case in Tableau. To load REST API data in Tableau using ZappySys drivers basically there are two approaches.Īpproach#1 You can use direct ODBC Connection to call ZappySys DriversĪpproach#2 Use SQL Server Connection in Tableau to send ZappySys Driver queries to ZappySys Data Gateway (using Linked Server OPENQUERY). Step By Step – Loading REST API data in Tableau Download and Install ZappySys ODBC PowerPack (API Drivers) – These drivers must be installed on Windows Machine (Can be different than Tableau Desktop / Server).You can download FREE SQL Express Version (DB Server) and SSMS from here (Client). We will use Linked Server to access REST API. Make sure SQL Server Instance is installed somewhere.Requirementsīefore we get started for step by step tutorial, make sure following requirements are met. Concepts / steps listed in this articles are mostly same for other type of API formats too (e.g. ZappySys API drivers are most advanced API drivers available in the market with many options to connect to virtually any REST / SOAP API data source. For demo purpose we will load ODATA API (JSON Format) using ZappySys JSON Driver. We will use ZappySys API Drivers to read data from Web API or Local XML / JSON / CSV Files without doing any coding or ETL. In this article we will cover how to import REST API in Tableau, We will also look at various examples to read from Files or any JSON / XML SOAP / CSV API in few clicks. It comes with many out-of the box connectors to pull data from some popular data sources but still it seriously lakes capability to consume data from millions of other REST / SOAP data sources out there for which Tableau not going to create native connectors. Tableau is one of the most popular Reporting / Visualization tool for BI / Data analytics. 13.7 Preview SOAP API Response / Generate SQL Code for SOAP API Call.13.6 Create DSN using ZappySys XML Driver to call SOAP API.13.5 Using SoapUI to test SOAP API call / Create Request Body XML.13.4 Video Tutorial - Introduction to SOAP Web Service and SoapUI tool.13.3 Example SQL Query for SOAP API call using ZappySys XML Driver.12.0.5 Use -FAST Option to enable Stream Mode.12.0.4 Consider using Metadata / Data Caching Option.12.0.3 Consider using pre-generated Metadata / Cache File.12.0.2 Avoid Special features in SQL Query (e.g.12.0.1 Use Server-side filtering if possible in URL or Body Parameters.12 REST API / XML SOAP Performance Tips for Tableau.11 Other settings for REST API / SOAP XML Call in Tableau.10 REST API / SOAP Web Service Connection Settings for Tableau.9.3 Paginate by URL Path (Loop until no record). ![]() 9.2 Paginate by URL Parameter (Loop until certain StatusCode).9 REST API / XML SOAP Pagination Settings for Tableau.5 Read data from JSON Files in Tableau (Single or Multiple).4 Passing Parameters to REST API calls in Tableau (Dynamic SQL). ![]()
