Frequently Asked Questions

How do I import this workflow into n8n?

Download the JSON file from your subscription dashboard, go to your n8n workspace, click the import button, select "Import from File", and upload the JSON. The entire workflow graph will load instantly, ready for configuration.

What credentials do I need to provide?

Each workflow lists required credentials in its description (e.g., Slack API key, GitHub token, PagerDuty account). You connect your own credentials—the workflow file contains only placeholder names, no actual API keys or secrets.

Are the credentials included in the JSON file?

No. For security, credential IDs are sanitized before distribution. You connect your own accounts when you first run the workflow. n8n will prompt you to authenticate each service.

Can I edit or customize the workflow after importing?

Yes, absolutely. Once imported, the workflow is yours to modify. You can change node logic, add/remove steps, adjust schedules, or integrate with different services. All changes are saved in your n8n workspace.

What n8n version is required?

These workflows use standard n8n-nodes-base node types (released 2022+). They work on n8n Cloud, self-hosted versions 0.180+, and Docker deployments. Community nodes (if required) are noted in the workflow description.

What if something breaks after I import it?

Check the workflow description for setup steps and credential names. Most issues are credential-related. If you get stuck, email support@autoflowworks.com with a screenshot of the error, and we'll help you troubleshoot.

Can I use this workflow for my customers or business?

Yes. The commercial-use license lets you keep, customize, and deploy the workflow for your business or clients. You can redistribute customized versions (except the original unmodified JSON without an active subscription).

Will the workflow receive updates?

Yes. When we improve a workflow (fix bugs, add features, optimize node types), you'll get the updated JSON for free. Check your subscription dashboard for new versions.

Do I need n8n Pro or a paid plan?

Not necessarily. These workflows run on n8n Free if you have enough execution time and storage. For production use (frequent triggers, high data volumes, many webhooks), you may want n8n Cloud Pro or higher. Check n8n's pricing for details.

Can I ask for a custom workflow?

Yes! We offer custom workflow design for specific DevOps/SRE use cases. Visit /custom-solutions or email support@autoflowworks.com with your requirements for a quote.
