 If you combine pipeline parameters and a custom event trigger, you can parse and reference custom `data` payloads in pipeline runs. Because the `data` field in a custom event payload is a free-form, JSON key-value structure, you can control event-driven pipeline runs.

 Event-driven architecture (EDA) is a common data integration pattern that involves production, detection, consumption, and reaction to events. Data integration scenarios often require customers to trigger pipelines based on events happening in storage account, such as the arrival or deletion of a file in Azure Blob Storage account. Data Factory and Synapse pipelines natively integrate with [Azure Event Grid](https://azure.microsoft.com/services/event-grid/), which lets you trigger pipelines on such events.

 > If the blob storage account resides behind a [private endpoint](../storage/common/storage-private-endpoints.md) and blocks public network access, you need to configure network rules to allow communications from blob storage to Azure Event Grid. You can either grant storage access to trusted Azure services, such as Event Grid, following [Storage documentation](../storage/common/storage-network-security.md#grant-access-to-trusted-azure-services), or configure private endpoints for Event Grid that map to VNet address space, following [Event Grid documentation](../event-grid/configure-private-endpoints.md)
