--- title: Gerrit API Integration on Truto slug: gerrit category: CI/CD canonical: "https://truto.one/integrations/detail/gerrit/" --- # Gerrit API Integration on Truto **Category:** CI/CD **Status:** Generally available ## Unified APIs ### Unified CI/CD API - **Branch-Protection-Rules** — The branch protection rule represents protection settings applied to branches in a repository - **Branches** — The branch represent a branch in the CI/CD. - **Pull-Requests** — - **Repos** — The repo represent a repository in the CI/CD. ## How it works 1. **Link your customer's Gerrit account.** Use Truto's frontend SDK; we handle every OAuth and API key flow so you don't need to create the OAuth app. 2. **Authentication is automatic.** Truto refreshes tokens, stores credentials securely, and injects them into every API request. 3. **Call Truto's API to reach Gerrit.** The Proxy API is a 1-to-1 mapping of the Gerrit API. 4. **Get a unified response format.** Every response uses a single shape, with cursor-based pagination and data in the `result` field. ## Use cases - **Automate security scanning on Gerrit Changes before merge** — Application security SaaS products can fetch open Gerrit Changes (mapped as Pull Requests), scan the latest patchset for vulnerabilities, and post review votes and inline comments back — blocking merges when issues are found, all without building Gerrit-specific API logic. - **Calculate engineering productivity metrics across Gerrit and other SCM tools** — Developer productivity platforms can ingest repos, branches, and change history from Gerrit alongside GitHub or GitLab data through a single unified schema, enabling consistent DORA metrics and cycle-time analysis without maintaining separate integrations. - **Audit code review policies for compliance enforcement** — Compliance and governance SaaS products can read branch protection rules and repository configurations from Gerrit to verify that mandatory review policies (e.g., two-person approval) are enforced, automatically flagging drift from organizational standards. - **Sync Gerrit review activity with project management tools** — Workflow automation platforms can track the lifecycle of Gerrit Changes — from open to merged or abandoned — and trigger downstream actions like updating issue tracker tickets or notifying stakeholders, giving end users visibility without leaving their existing tools. - **Provide unified repository and branch visibility for platform engineering teams** — Internal developer platforms and service catalogs can list all Gerrit projects and branches alongside repos from other providers, giving engineering leaders a single pane of glass over their entire codebase without dealing with Gerrit's unique API conventions. ## What you can build - **Cross-platform code review dashboard** — Surface open Gerrit Changes alongside GitHub and GitLab pull requests in a single, normalized view so engineering managers can track review bottlenecks across all SCM tools. - **Automated merge-gate for security and quality checks** — Trigger scans on new Gerrit patchsets and programmatically vote on Changes to approve or block merges based on your product's analysis results. - **Branch protection policy audit report** — Continuously monitor Gerrit branch protection rules and submit requirements across all repositories to generate compliance-ready audit reports for SOC2 or ISO27001. - **Time-to-merge and review depth analytics** — Analyze historical Gerrit Changes — including patchset iterations, reviewer assignments, and merge timestamps — to calculate review cycle times and team throughput metrics. - **Repository inventory and configuration scanner** — Enumerate all Gerrit projects with their branch structures and access configurations to power a service catalog or detect misconfigured repositories at scale. - **Change lifecycle event triggers** — React to Gerrit Change status transitions (opened, merged, abandoned) to drive downstream workflows like Jira ticket updates, Slack notifications, or deployment pipelines. ## FAQs ### How does Truto map Gerrit's data model to the Unified CI/CD API? Gerrit Projects map to the Repos resource, Gerrit Branches map to Branches, Gerrit Changes and Patch Sets map to Pull-Requests, and Gerrit's submit rules and project access configurations map to Branch-Protection-Rules. This abstraction lets you work with a standard schema without dealing with Gerrit's commit-based review model directly. ### What authentication methods are supported for connecting to Gerrit instances? Gerrit is almost exclusively self-hosted, so authentication varies by customer. Common methods include HTTP Basic Auth with generated passwords, OAuth (when configured), and LDAP-backed credentials. Truto handles these variations so you don't need to build auth logic for each customer's Gerrit deployment. ### Is the Gerrit integration available today or built on request? The Gerrit integration is built on request. Truto's team will work with you to set up the connector against Gerrit's REST API, map it to the Unified CI/CD API schema (Repos, Branches, Pull-Requests, Branch-Protection-Rules), and handle the nuances of your customers' Gerrit configurations. ### How does Truto handle pagination and rate limiting for Gerrit's API? Gerrit's REST API uses offset-based pagination and, being self-hosted, typically does not enforce standardized rate limits — though individual deployments may have custom throttling. Truto manages pagination automatically and adapts to the specific behavior of each connected Gerrit instance. ### Can I write data back to Gerrit, such as posting review comments or votes? Gerrit's API supports write operations including posting review comments, setting label votes (e.g., Code-Review +1, Verified -1), and submitting Changes. The exact write capabilities available through Truto depend on the integration scope defined during the on-request build process. ### How does Truto handle connecting to multiple customers' self-hosted Gerrit instances? Each of your end users connects their own Gerrit instance through Truto. Truto manages the per-customer connection details — server URLs, authentication credentials, and API versioning differences — so your application uses a single, consistent API regardless of how many distinct Gerrit deployments your customers run.
