Introducing listeners in Data Connection for capturing inbound webhooks

Date published: 2026-01-08

Listeners, a new Data Connection feature, enables you to receive inbound webhook events directly into the Palantir platform. This feature will be released in public beta the week of January 5th. Integrating real-time events from external systems into Foundry has traditionally been challenging when those systems lack OAuth 2.0 authentication support or cannot format payloads to match standard Foundry API endpoints. Listeners address this gap by provisioning URL endpoints that implement system-specific message signing and verification schemes—agnostic to data shape—providing a simple, low-latency mechanism to accept event streams from external sources.

For more information, including a list of supported listeners and set up guides, review the Listeners documentation.

How listeners work

To accept inbound events from external systems, Data Connection listeners provision a URL endpoint, implement the specific message signing or other verification schemes for specific external systems, and allow a simple and low-latency mechanism to receive event streams into the Palantir platform. Leverage the listener output stream with streaming pipelines, automations, or batch analysis to create powerful event-processing workflows.

Subdomain configuration and zero-downtime endpoint rotation

You can generate a subdomain for your listener to establish a distinct ingress point with a wider range of network ingress compared to the rest of your Foundry enrollment. This isolates webhook traffic from other platform operations, provides additional control over external system connections, and enables unified governance with additional security benefits.

Listeners also come with an endpoint rotation capability that provides protection if a listener endpoint is compromised. Migrate to a new endpoint with zero downtime if the URL is accidentally exposed. When rotating your endpoint, you can set an expiration date for seamless zero-downtime transitions, or delete the old endpoint immediately if faster action is required. Once an endpoint expires, it will no longer process events.

Data Connection listeners expand Foundry's integration capabilities by removing authentication and payload formatting barriers that previously prevented real-time event ingestion from external systems.

For more information, see the listener subdomains documentation.

Get started with listeners

Enrollment administrators can enable listeners by toggling the feature on in the Data Connection page under Control Panel.

Once enabled, users can access the Listeners tab from within the Data Connection application to connect the Palantir platform to external systems and workflows.
