About this skill
Automate n8n Credential Management
Setting up credentials manually in the n8n UI is a bottleneck for automated deployments and CI/CD pipelines. This skill provides a robust, developer-ready pattern for creating n8n credentials via the REST API, eliminating manual configuration steps.
What it does
- Automates the creation of diverse credential types including OAuth2 (Google Sheets, Drive, Gmail), HTTP Header Auth, and Basic Auth.
- Solves the notorious "allOf schema" bug in the n8n API that causes cryptic validation errors during OAuth2 credential creation.
- Provides ready-to-use implementation patterns for both shell (cURL) and Python.
Why use this skill
Standard LLM prompts often fail to account for n8n's strict OpenAPI validation requirements, which demand specific hidden fields like serverUrl even when they are empty. This skill embeds the specialized logic required to bypass these validation errors, ensuring your automation scripts work on the first try. It is essential for developers managing multi-tenant n8n instances, performing environment migrations, or building infrastructure-as-code (IaC) for automation workflows.
Supported Outputs
The skill generates structured API calls and Python scripts that return the official n8n credential metadata (ID, timestamps, and type) upon successful execution.
