Guide: Google Pub/Sub Connector User Guide

1.3.0

October 4, 2026

What’s New

  • This release includes general security fixes.

  • The MuleSoft IdP Configuration type now includes the optional Token Endpoint field. Set Token Endpoint so a Workload Identity Federation connection requests tokens from the control plane where the app runs. If you leave Token Endpoint blank, the connector uses https://anypoint.mulesoft.com/accounts/api/v2/oauth2/token. For EU1, set https://eu1.anypoint.mulesoft.com/accounts/api/v2/oauth2/token. If the value is not an HTTPS URL with a host, token exchange fails with Token Endpoint must be an https URL.

Fixed Issues

Issue Resolution ID

The On message listener source now routes streaming-pull traffic through the host and port configured in the Override Host and Override Port fields, consistent with publish and unary subscribe operations. Previously, the source ignored these settings and connected to the default public endpoint.

W-23349394

The Create Snapshot, Delete Snapshot, Seek, and List Snapshots operations now automatically retry on transient errors, instead of failing immediately.

W-22579551

These libraries are upgraded:

  • The grpc-api, grpc-netty-shaded, and grpc-core libraries are upgraded to version 1.81.0.

W-22579551

1.2.0

November 16, 2025

What’s New

  • The connector now includes the new Override Host and Override Port fields to direct all API calls to the specified host and port instead of the default public endpoint. This allows you to configure custom host and port settings to route traffic through private endpoints, enabling compliance with security policies that require avoiding public internet connections.

  • The connector now includes the new Acknowledge Message and NACK Message operations to acknowledge or negatively acknowledge messages. The On message listener source now includes the new Acknowledgment Mode field, providing full control over the message processing lifecycle. This prevents infinite processing loops when downstream systems fail and provides better error recovery mechanisms.

  • The connector now includes the new Authentication Method and MuleSoft IdP Configuration fields to add Workload Identity Federation (WIF) support, enabling federated authentication through MuleSoft as an identity provider.
