Apigee Release Roundup: June 2025

To help you stay in the loop about our latest product releases, we’re starting a new monthly series to highlight what’s new. Here’s our latest roundup of what we’ve released in the last two months.

Apigee X / hybrid: New releases

  • New AI policies: Four new Apigee policies supporting LLM/GenAI workloads are now available in Public Preview:

    • SemanticCacheLookup policy

    • SemanticCachePopulate policy

    • SanitizeUserPrompt

    • SanitizeModelResponse

      The Apigee semantic caching policies enable intelligent response reuse based on semantic similarity. Using these policies in your Apigee API proxies can minimize redundant backend API calls, reduce latency, and lower operational costs.

      The Model Armor policies protect your AI applications by sanitizing user prompts to and responses from large language models (LLMs). Using these policies in your Apigee API proxies can mitigate the risks associated with LLM usage by leveraging Model Armor to detect prompt injection, prevent jailbreak attacks, apply responsible AI filters, filter malicious URLs, and protect sensitive data.

  • Support for Server-Sent Events: Apigee now supports continuous response streaming from server-sent event (SSE) endpoints to clients in real time. The Apigee SSE feature is useful for handling large language model (LLM) APIs that operate most effectively by streaming their responses back to the client. SSE streaming reduces latency, and clients can receive response data as soon as it is generated by an LLM. This feature supports the use of AI agents that operate in real time environments, such as customer service bots or workflow orchestrators. For more information, see Streaming server-sent events.

  • GA of Gemini Code Assist’s code spec creation features for Apigee: These features in Gemini Code Assist allow you to use natural language prompts to design, create, iterate, and manage OpenAPI specifications with the following capabilities:

    • Gemini-powered API design: Generate high-quality OpenAPI specifications from natural language prompts to the Apigee tool in Gemini Code Assist Chat, leveraging the Gemini model and the enterprise context of your API hub.

    • Spec iteration: Refine existing or newly generated specifications using the intuitive Gemini chat interface.

    • Integrated testing: Quickly validate your APIs by deploying them to a local or Google Cloud-hosted mock server.

    • Streamlined workflow: Publish your completed API specifications directly to Apigee API hub and kick-start proxy development by creating Apigee proxy bundles from your API specifications.

    • Duplicate endpoint detection: Proactively identify and prevent the creation of duplicate API endpoints already registered in your API hub.

      For more information and usage instructions, see Designing and editing APIs, Tutorial: Use Gemini Code Assist to design, develop, and test APIs in Apigee, and Setting up Apigee API Management in Cloud Code for VS Code.

  • Apigee Extension Processor support for request and response body processing: When creating a load balancer service extension, you can customize the behavior of the extension processor proxy to support request body processing, response body processing, or a combination of the two. For more information, see Get started with the Apigee Extension Processor.

  • Support for large payloads: We now support payloads up to 30MB; see docs here.

  • New flow variables for VerifyAPIKey policy: Two new flow variables have been added to the VerifyAPIKey policy: app_group_app and app_group_name. See Using flow variables for more details.

  • Management API: We now offer a Management API that allows users to list all recent debug sessions for a given proxy, regardless of revision or environment and current deployment status. This API is available for use, and is now used to populate all recent debug sessions in the Apigee Debug UI. See info on this API method here.

  • API hub updates

    • Auto-provisioning: API hub is now automatically enabled for all new Apigee organizations in supported regions.
    • API overview and metrics: The Get Started with API hub page now includes new charts and scorecards to provide a quick overview of your API landscape.
    • For more information, see Get started with API hub.
    • Attach and manage Tags: You can now add custom tags to your APIs and API deployments, making it easier to organize, categorize, and discover your API resources in API hub. Tags can also be used to conditionally allow or deny policies to a specific resource. For more information see Attach and manage tags.
    • New region availability: API hub is now available in 30+ regions; see region support here.

Apigee Advanced API Security: New releases

  • New Anomaly Detection ML model in Abuse Detection: We’ve introduced a new and improved machine learning model for anomaly detection in Advanced API Security. This new model includes the following improvements:

    • Trained on your specific traffic patterns: The new model is trained exclusively on your organization’s historical API traffic data. It continues to learn from your API traffic patterns over time to increase accuracy.

    • Engineered by Google for anomaly detection: The new model is a custom Vertex AI-based machine learning model, engineered and also used internally by Google specifically to detect anomalies in traffic patterns.

      The new anomaly detection model replaces the old model, with no customer-facing changes to the API or UI. Note: The new model is not available for VPC-SC customers at this time.

  • Raw data for detected traffic: You can now view raw data underlying an API security incident report, including the request verb used, client IP address, API proxy, developer app, and other attributes. See docs here.

  • New region support: Advanced API Security is now available in africa-south1.

Portals and Distribution: Updates

  • Integrated Portal Admin UI: Now available in Google Cloud Console, eliminating the need to switch between different UIs.
