create-credential
Create credentials for n8n workflow nodes to authenticate with external services like Cloudflare, GitHub, and Slack. Use get-credential-schema first to identify required fields.
Instructions
Create a credential that can be used by nodes of the specified type. The credential type name can be found in the n8n UI when creating credentials (e.g., 'cloudflareApi', 'githubApi', 'slackOAuth2Api'). Use get-credential-schema first to see what fields are required for the credential type you want to create.
