The Complete Guide to Integrating GitHub and Trello for DevOps + Project Management workflows.
Stop manually shuttling data. Connect your system of record directly to your workflow to automate code sync & issue tracking in real-time. This guide details the architecture of passing payloads natively between GitHub and Trello.

Why Integrate GitHub and Trello?
In modern software development, a persistent operational divide often exists between product managers and engineers. Product managers and scrum masters live in project management tools like Trello, organizing sprints, writing user stories, and tracking overall project momentum. Engineers, however, live in their version control system—GitHub—managing branches, writing code, and reviewing pull requests. When these two environments are disconnected, chaos ensues. Product managers are forced to constantly interrupt developers via Slack to ask, 'Is this feature deployed yet?' while engineers waste time manually updating Trello cards with links to their commits. Integrating GitHub directly with Trello bridges this gap, creating a unified, automated Agile workflow. By connecting the two platforms, you can link specific GitHub pull requests, commits, and issues directly to Trello cards. This integration provides product managers with real-time, visual updates on the status of the code without ever having to log into GitHub or read a command line. Conversely, engineers can trigger automated movements on the Trello board (e.g., moving a card from 'In Progress' to 'Code Review') simply by changing the status of a Pull Request in GitHub. This bidirectional flow of information drastically reduces context switching, eliminates manual status updates, and ensures both technical and non-technical stakeholders are perfectly aligned on sprint progress.
Top Use Cases
Real-Time Pull Request Status on Trello Cards
The most powerful feature of this integration is the visual status sync. When a developer attaches a GitHub Pull Request (PR) to a Trello card, the card displays a dynamic badge showing the real-time status of that PR (e.g., Open, Merged, Closed, or Failed Checks). If a CI/CD pipeline fails a test on the PR, the badge on the Trello card instantly turns red, alerting the product manager that the feature is blocked, all without the developer having to manually type a status update.
Automated Kanban Board Movement
Trello's native automation (Butler) can interact directly with the GitHub integration. You can set up rules that automate your sprint board based on developer actions. For example, when an engineer merges a Pull Request into the 'main' branch in GitHub, Butler can automatically move the associated Trello card from the 'Code Review' list to the 'Ready for Deployment' list. This ensures your project management board perfectly mirrors the actual state of your codebase.
Creating GitHub Issues from Trello
When QA testers or beta users report bugs, they are often logged as Trello cards. To ensure these bugs enter the engineering workflow, the integration allows project managers to generate a GitHub Issue directly from the Trello card with one click. The new GitHub Issue automatically imports the Trello card's description, labels, and attachments, creating a permanent link between the bug report in Trello and the issue tracking in GitHub.
Branch Creation from Trello
To enforce naming conventions and branch hygiene, engineers can start their work directly from Trello. Using the GitHub Power-Up, a developer can click 'Create Branch' directly on a Trello card (e.g., 'Fix Login Bug'). The integration automatically creates a new branch in the linked GitHub repository, automatically naming the branch based on the Trello card's title and ID. This ensures every branch in GitHub is explicitly tied to a documented business requirement.
Connection Capabilities
Prerequisites
- An active Trello account with Board Admin privileges to enable Power-Ups.
- An active GitHub account with Repository Admin privileges to authorize the Trello application.
- A clear understanding of your team's Git workflow (e.g., feature branching, pull request review process).
Step-by-Step Implementation Guide
Enable the GitHub Power-Up in Trello
Begin by bringing GitHub into your Trello workspace. Open your Trello Sprint board and click the 'Power-Ups' button in the top right menu. Search the directory for 'GitHub' and click 'Add'. You will be prompted to authorize the Power-Up. Log into your GitHub account and grant Trello the requested permissions. You can choose to grant access to all repositories or limit access to specific repositories associated with this specific Trello board.
Attach a Pull Request or Issue to a Card
Once authorized, open any Trello card. You will now see a 'GitHub' button under the 'Power-Ups' section on the right side of the card. Click it, and select 'Attach Pull Request' or 'Attach Issue'. You can either search for the item by name or paste the direct GitHub URL. Once attached, the card will display a rich preview badge showing the current status (e.g., 'Open', 'Merged', 'Closed') and the assignee.
Configure Butler Automations for Board Movement
To eliminate manual drag-and-drop, configure Trello's Butler automation to listen to GitHub events. Click the 'Automation' button at the top of your Trello board. Create a new Rule. Set the Trigger to 'When a pull request attached to a card is merged'. Set the Action to 'Move the card to the top of list [Done]'. This simple rule ensures that the moment an engineer merges their code in GitHub, the product manager sees the task cross the finish line in Trello.
Link Commits to Trello Cards via Commit Messages
Engineers don't even need to open Trello to link their work. Every Trello card has a unique, short URL (e.g., `trello.com/c/AbC123Xy`). When a developer makes a commit in their terminal, they can simply paste that short URL into their commit message (e.g., `git commit -m "Fix database timeout issue https://trello.com/c/AbC123Xy"`). Because the Power-Up is active, GitHub will read that URL and automatically attach the commit to the corresponding Trello card.
Customize the GitHub Badge Display
To prevent visual clutter on your Trello board, you can customize what information is shown on the front of the cards. Click the 'GitHub' Power-Up settings in the Trello board menu. Here, you can toggle whether to show Pull Request statuses, commit counts, or Issue labels on the front of the card. Showing PR statuses on the front is highly recommended so product managers can gauge sprint health at a glance without opening individual cards.
Establish Team Protocols
Technology requires discipline. Establish a strict protocol for your engineering team: No Pull Request can be merged unless it is attached to a Trello card. This enforces traceability, ensuring that no 'rogue code' enters the main branch without being tied to an approved user story or bug report managed by the product team in Trello.
