Data From Rest API RRS feed

  • Question

  • I need to extract data from enterprise systems through REST API that return JSON data as Response. I have some specific query around this

    1. Which Activity should i use within ADF to extract data from REST API.
    2. Can i use ADF to extract both Historical and Incremental data from Rest API
    3. If there is no Parameter within REST API that supports both Historical and Incremental, how often do i need to call the API from ADF or should i go for Event Hub to get data into target systems.
    4. How do i know if the data in source system is changed from the Rest API

    Please help with best possible design in Azure for handling REST API..

  • Hi there,

    One way to go about this is by using event hubs in conjunction with Azure Blob Storage or Azure Data Lake Store ( on which you can perform analytics later). To read more, please refer:


    Unfortunately, with REST API as source, there's no way to track updates and incrementally copy data.

    The best way would be to set up event hubs and set up an event based trigger. To read more, please refer :

    Did you get a chance to try out the solution ? Does it work well for you ?

  • Hi Chirag,

    There is some change in the requirement. Below is what i have highlighted

    • All the enterprise data will be available through Custom Service Bus and there are supporting REST API .
    • There is a need for real time and historical (analytical) type of reporting.

    Based on the above requirement i have some questions, also i have included a high level Solution diagram please see if this will be feasible.

    1.    Query 1: For the initial run how will i perform historical load.

    2.    Query 2: For the subsequent/incremental load i can use Event Hub. Will that be correct assumption?

    Sorry for the delayed response. 

    For the initial run, you can use Azure Data Factory to directly copy from the REST API, the historical data to Azure Data Lake Store.

    For subsequent runs, you can use event hubs to feed data into blob storage or Azure Data Lake Store. Your solution is definitely feasible :).
