Webhook

Last updated on Jul 07, 2025

We have migrated our webhooks infrastructure for better scalability and throughput. As a result, the old Webhook URLs are deprecated and will stop working soon. Please migrate to the new webhook URL (provided in the Set up Webhook section of your Pipeline Overview page) to avoid disruption in your data loading operations.

Webhook URL

You can use Webhook to push data from your Source to Hevo in real-time. The Hevo Pipeline then replicates this data to your Destination database or data warehouse.

A Webhook-based Pipeline is useful when new data is actively generated in your Source. Instead of Hevo checking for updates at specific intervals, you can configure the URL provided by your Webhook Pipeline in the application and directly send the data to Hevo as soon as it is generated. You can also configure your Webhook Pipeline using the Hevo API and send one or more files up to 16 MB each in an API call.


Source Considerations

  • Webhook only supports JSON files up to 16 MB in size.

Limitations

  • Hevo does not load data from a column into the Destination table if its size exceeds 16 MB, and skips the Event if it exceeds 40 MB. If the Event contains a column larger than 16 MB, Hevo attempts to load the Event after dropping that column’s data. However, if the Event size still exceeds 40 MB, then the Event is also dropped. As a result, you may see discrepancies between your Source and Destination data. To avoid such a scenario, ensure that each Event contains less than 40 MB of data.
