Automate Zendesk to GitHub Issue Sync with n8n

What this workflow does

This workflow automatically connects Zendesk tickets with GitHub issues. It solves the problem of manually copying ticket details into GitHub and prevents duplicate issues. The result is faster updates for engineering teams and better tracking of user requests.

When a new Zendesk ticket is made, this system either creates a new GitHub issue or updates an existing one. It adds comments from Zendesk to GitHub and writes the issue number back to Zendesk for future reference.

Who should use this workflow

This workflow is useful for teams that handle customer support in Zendesk and use GitHub to track bugs or features. It helps support agents who spend time copying tickets to GitHub or engineering teams that face duplicate or missing issues.

Users need basic knowledge of API keys and a Zendesk setup with a custom field for GitHub issue numbers. Also, they must have GitHub repo access to create and comment on issues.

Tools and services used

• n8n: The automation platform running the workflow.


• Zendesk API: To get ticket details and update tickets with GitHub issue info.


• GitHub API: To create issues and add comments on GitHub repositories.

Inputs, Processing, and Outputs

Inputs

• Webhook event with new Zendesk ticket data.


• Zendesk ticket ID from the webhook payload.


• Custom field in Zendesk that stores GitHub issue number (custom field ID: 6721726848029).

Processing steps

1. The Webhook node receives a new ticket event from Zendesk.


2. The Zendesk node fetches complete info about the ticket using the ticket ID from the webhook.


3. A Function node reads custom fields to find if there is an existing GitHub issue number saved.


4. An IF node checks if the GitHub issue number exists.


5. If no issue number exists, a GitHub node creates a new issue using the Zendesk ticket subject as the issue title.


6. If the issue number exists, a GitHub node adds a comment to that existing issue with the latest Zendesk ticket comment.


7. After creating a new issue, a Zendesk node updates the Zendesk ticket by writing the new GitHub issue number into the custom field.

Outputs

• New or updated GitHub issue linked with the Zendesk ticket.


• Zendesk ticket updated with the GitHub issue number for future tracking.


• Automatic comments added from Zendesk tickets to GitHub issues.

Common failures and fixes

GitHub API authentication error

This happens if API keys are wrong or expired. Fix by updating GitHub API credentials in n8n.

Zendesk ticket update fails

Check if the custom field ID is correct and ensure the Zendesk API user has permission to update tickets.
