Key Facts
- Limitation
- The n8n node does not support SSL certificate configuration.
- Workaround
- Use the HTTP Request node for n8n API calls that require SSL certificate options.
- Affected use case
- Servers that require an SSL connection with certificate configuration.
Recommended Steps
- Confirm the failure is related to SSL certificate requirements.
- Replace the n8n node API call with an HTTP Request node.
- Configure the request URL, method, authentication, and SSL options.
- Test the request against the same n8n API endpoint.
- Keep the n8n node for simpler API calls that do not require SSL certificate configuration.
Verification
- The HTTP Request node reaches the API endpoint successfully.
- The returned response matches the operation you expected from the n8n node.
Warnings
- Do not disable SSL verification as a shortcut unless you understand the security tradeoff.
- Keep API credentials and certificates out of exported public workflow templates.
