What problem does it solve?

This skill helps teams manage, configure, and test credentials for n8n automations across REST APIs, OAuth flows, and built-in credential types.

Core Features & Use Cases

  • Discover available credential types and their schemas for quick integration on new nodes.
  • Create, update, test, and manage credentials across projects with secure handling and redaction.
  • Use cases include configuring API keys for external services, OAuth2 flows, and HTTP authentication for custom endpoints.

Quick Start

Connect an API credential in n8n and run a test to verify access.

Frequently Asked Questions about credentials

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I test and manage OAuth2 credentials for n8n workflows?▼

OAuth2 credentials in n8n are tested through structured operations that verify external service access and validate callback flows. This skill handles OAuth2 configuration alongside API keys and HTTP authentication with secure redaction.

How do I configure REST API authentication for custom endpoints in n8n?▼

To configure REST API authentication for n8n, you use httpCustomAuth JSON definitions and service-specific credential schemas. This process creates and updates credentials with built-in validation and secure redaction for custom endpoints.

Can I discover available credential schemas for new n8n integrations?▼

You can discover available credential types and their schemas for quick integration on new n8n nodes. This feature allows teams to find and apply the correct REST API and OAuth credential structures needed across multiple service integrations.

What is the best way to securely update API keys across n8n projects?▼

The best way to securely update API keys across n8n projects is through structured credential management operations with built-in validation. This ensures secure handling and redaction of sensitive authentication data during updates and testing.

Does this approach work with service-specific credential types and OAuth callbacks?▼

Yes, this approach works with service-specific credential schemas and implements structured operations for OAuth callbacks. It applies to scenarios involving REST API credentials, OAuth flows, and httpCustomAuth JSON definitions across multiple n8n nodes.
