Explain Tableau hyper API

The Hyper API provides a collection of functions that you can use to simplify your interactions with Tableau extract files (hyper). To build new extract files, or to open existing files, you can use the API to upload, remove, edit, or read data from those files. Using Hyper API , developers and administrators may do as follows.

• Creates extract files which are currently not provided by Tableau for data sources.
• Automate custom processes for extracting, transforming and loading ETL for example, implement rolling window updates, or custom incremental updates.
• Retrieve data from file with an extract.

Features of Tableau Hyper API

The Hyper API is the evolution of Extract API. The Hyper API allows developers and administrators to create.hyper files from those files and upload, remove, update, and read data. New features Hyper API comes with the following.

• Full CRUD:

Reading, downloading, removing and inserting data into.hyper files;

• Full speed:

Use full Hyper speed to create Tableau hyper files.

• Direct loading of CSV:

Loading files directly from CSV instead of writing code to do so.

• SQL-based API:

It unleashes SQL’s ability to communicate with .hyper files.

• Multi-table:

Build extracts of multi-table data that suit your pattern.

The Hyper API provides access to new features, in addition to supporting the features of the previous Extract API 2.0 to create and update extract files.

• Within .hyper files also known as CRUD operations, you can create, read, edit, and delete data.
• You can use Hyper maximum speed for extract file development and updating.
• You can load data from CSV files directly, much quicker and without having to write complex code to do so.
• In.hyper files, you can use the SQL power to communicate with the data. The Hyper API provides methods for executing Tableau hyper SQL on files running on .hyper. For more info Tableau Training

Tableau Hyper API includes the means to communicate with files from the local.hyper sample.

Supported languages in Tableau Hyper API

The Hyper API supports exclusively 64-bit platforms. The Hyper API libraries are available for the programming languages as follows:

• Python (3.6, or higher)
• C++ (or newer: C++11)
• Java (Java 8, or higher)
• C#/.NET (.NET default 2.0)

Although the  Hyper API is intended to operate on newer versions of these languages, it may not be tested. In this article let us discuss about Tableau Hyper API in Python 3.6.

Tableau Hyper API to fulfill Python needs

 The Hyper API supports only 64-bit interpreters. For example, a 64-bit version of Python is required.

The Python 3.6 and 3.7 features with the Hyper API.

While it is believed that the Hyper API also operates with newer versions, this was not checked through testing.

• Use https:/python.org/downloads to download Python 3.6 or 3.7.
• Download a 64-bit version, the update is classified as Windows x86-64 for example for Window.
• On Windows, we suggest that you pick the Add Python 3.x option to PATH when installing.

Setup with Python hyper API                                                                        

1. The following instructions assume you have set up a Python virtual environment. See venv-Creation of virtual environments in Python Standard Library for more information on creating virtual environments.

2. Open a terminal and navigate to the directory at venv.

3. Using pip install the Tableau Hyper API module.

4. Pip have tableau Hyper API enabled

If you have previously installed Tableau Hyper API you can use the command below to upgrade to the latest version.

Pip Download Tableau Hyper API—upgrade

Installations running Linux require pip version 19.3 or newer. Note that pip versions 20.0 and 20.1 do not work due to pip problems.

Alternatively, the Python Hyper API package (.whl file) can be downloaded for your operating system. See Hyper API-Download and Release of Products.

• Install the.whl file you downloaded using pip.
• Install [path to whl file] on Windows: Scripts\pip
• [Path to whl file] Install bin or pip on Linux or Mac OS.

5. Download examples, and try them:

• Download the Python.zip file and unzip it for your operating system.
• Open a terminal, and navigate to the directory of examples.
• Run Python Examples (try insert data into single table.py, for example).
• [Insert data into single table.py [venv directory]\Scripts\python.
• On Linux or Mac OS: insert data into single table.py [venv directory]/bin / python

Web hooks in Tableau Hyper API

A web hook is an API term that is becoming increasingly popular. As events could explain more and more of what we do on the web, web hooks are becoming ever more important. They are extremely useful for executing event reactions, in a resource-light way.

You can download the Postman collection directly from Github and create your own Web hooks to get started on this function. IFTTT is my favorite website for integration with other services. I use IFTTT for example to send me a Slack message to update my favorite Tableau workbook. Personally, it is the happiness formula.

Tokens for personal access in Tableau Hyper API

Now, let us talk about Tableau REST API and Hyper API authentication. Today, when you use our REST API to sign in to your server or Tableau Online, you need to submit your username and password in a file. In this YouTube video, learn how to sign in, what a REST API is, how it applies to the provisioning, permissions, and publishing, and more.

There is no need to type your password using Personal Access Tokens. This new token can be used to login to your server. There is no need to expose your account credentials in automation. But if your company uses SAML or some other form of Tableau authentication, you can also use the REST API.

The other benefits of the upcoming Personal Access Token tableau are as follows.

• Better security: Reduces the risks of revealing your credentials.
• Better tracking: Administrators can track where and for what reason a token is being used.
• Better governance: You may revoke the access to this token at any moment.
• Better management and handling: Every script or application may generate a token. If the password or email address is changed, the use of the API token won’t affect it.

The Launching of the Hyper API, Web hooks and Personal Access Token are in beta format and will be ready for release in 2019.

Use Case of Tableau Hyper API

 Link with the Hyper API to the data sources and write the data into extract files (in Tableau 10.5 and later in the.hyper file format. Write custom scripts which update or read data from existing extract files.

Benefits of Tableau Hyper API

You can use the Hyper API to build data extracts that enhance performance and provide offline access if you are able to link to your data. You can use the Hyper API to get the data into Tableau if you have data sources that are not currently supported. You can use the Hyper API to update the extract if you want to update data inside extract files. If you need to access data from an extract, you can now write a script which will read the extract data.

Conclusion

I hope you reach to a conclusion about Tableau Hyper API. You can learn more concepts of Tableau through Tableau online training.
