Event Listener

In this article

Overview

You can use this Snap to monitor calendar for new or updated event invitations.

Snap Type

Event Listener is a Read-type Snap that monitors the calender for new event invitations.

Prerequisites

  • Valid Exchange Online tenant.

  • Valid OAUth2 application in Azure Active Directory with all the required API permissions.

Support for Ultra Pipelines

Works in Ultra Pipelines. However, we recommend that you not use this Snap in an Ultra Pipeline. To know the list of Snaps that work in Ultra and the related caveats, see Snap Support for Ultra Pipelines.

Limitations

Probability of Snap failing with short polling interval is high.

  • Best practice is to add retry configured in snap settings.

  • Value less than 5 is error prone.

Error

Error handling is a generic way to handle errors without losing data or failing the Snap execution. You can handle the errors that the Snap might encounter when running the Pipeline by choosing one of the following options from the When errors occur list under the Views tab:

  • Stop Pipeline Execution: Stops the current Pipeline execution when the Snap encounters an error.

  • Discard Error Data and Continue: Ignores the error, discards that record, and continues with the remaining records.

  • Route Error Data to Error View: Routes the error data to an error view without stopping the Snap execution.

Learn more about Error handling in Pipelines.

Snap Settings

  • Asterisk (*): Indicates a mandatory field.

  • Suggestion icon (): Indicates a list that is dynamically populated based on the configuration.

  • Expression icon (): Indicates whether the value is an expression (if enabled) or a static value (if disabled). Learn more about Using Expressions in SnapLogic.

  • Add icon (): Indicates that you can add fields in the field set.

  • Remove icon (): Indicates that you can remove fields from the field set.

Examples

Monitor for new events in calendar

We use an example to monitor events in the calendar, where we have a Event Listener Snap which is configured to monitor the new events invitation in the calendar.

Let us configure the Snap setting in the Event Listener Snap and check how it runs and monitors the mailbox.
