An Event enables you to specify when and how frequently a Process Flow bound with it would be executed based on the polling frequency. It also overrides the parameters you have provided in the application source used in the Process Flow as an activity.

This page discusses the event having application type as Azure Blob.

You can create an Event using Azure Blob as a Source and use it in a Process Flow. Follow the steps given below to create an Azure Blob Event.

  1. Click Configure > EVENTS > Application.

  2. Click Create Application Event.


  3. In the Name field, enter a name for the event.

  4. In the Description field, enter a description for the event.

  5. In the Application field, select Azure Blob as the type of application source.

  6. In the Account field, select the Azure Blob account that you want to use as a source.
    You can also create an Azure Blob account by clicking the  icon, and then providing the following information on the Create New Account screen.

    Field Name

    Description

    Provide a name for this account. e.g. "MyAccount"

    A short, descriptive name that helps you re-use this account in future.

    Access Type

    This field governs the type of authentication you choose to connect to your Azure Blob.

    Note: You can select Azure AD, Shared Key, or Shared Access Signatures as the Access Type. Based on your selection, the next field will ask you for the required input (Id, Key, or Signature) to proceed. For example, if you select Azure AD as the Access Type, the next field in the form will be Tenant Id where you’d need to enter the Tenant Id of your Azure Blob account.

    You can select one of the following Access Types:

    1. Azure AD – This option facilitates OAuth based authentication and the user experience will be the same as the other OAuth apps.
      Once you select Azure AD as Access Type, you’ll require the Tenant Id to enter in the next field. To know how to get the Tenant Id refer to this page in the Microsoft Azure documentation.
      After clicking Continue, the user would need to enter the Azure credentials in a new window.
    2. Shared Key – Facilitates non-OAuth based authentication. To know how to get the Shared Key, refer to this page in the Microsoft Azure documentation.
      As you complete all the fields and click Continue, your account will be created and saved.
      You may want to test if you’d be able to connect this account with Azure Blob by clicking Test.
    3. Shared Access Signatures – Facilitates non-OAuth based authentication. To know how to get the Shared Access Signature, refer to this page in the Microsoft Azure documentation.
      As you complete all the fields and click Continue, your account will be created and saved.
      You may want to test if you’d be able to connect this account with Azure Blob by clicking Test.
