agents-store Single Workflow Import
Import one workflow into a running n8n instance. Two paths depending on source — official template or community JSON. All calls use ~~capability with automatic fallback (see CONNECTORS.md).
Pre-Import Checklist
Run these checks before any import:
- Verify instance connectivity — call
~~instance_auditto confirm the n8n instance is reachable and healthy. - Check for duplicate names — call
~~workflow_listand compare the incoming workflow name against existing workflows. If a duplicate exists, append a suffix (e.g.,Workflow Name (2)) or ask the user. - Confirm n8n version compatibility — note the instance version from the audit. Some nodes require minimum versions.
If any check fails, stop and report before proceeding.
Import Path 1: Official Template
Use this path when the workflow comes from the n8n template library (has a numeric template ID).
Step 1: ~~template_get(templateId, detail_level="full")
→ Retrieve the full template JSON with node definitions
Step 2: ~~workflow_validate(workflow_json)
→ Check for structural errors, missing node types, invalid connections
→ If validation fails → see Error Handling below
Step 3: ~~template_deploy(templateId)
→ Deploys with auto-fix enabled
→ Automatically strips credentials (they are NOT transferred)
→ Returns the new workflow ID
Auto-fix options available through ~~template_deploy:
- Fixes missing connection references
- Resolves deprecated node type names
- Strips credential data (credentials must be reconfigured manually)
- Adjusts node positions for readability
Import Path 2: Community JSON
Use this path for workflows from GitHub, n8n community forums, blog posts, or any raw JSON source.
Step 1: Fetch the raw JSON
→ If URL provided: download the JSON file directly
→ If file provided: read from local path
→ Verify it is valid JSON with a "nodes" array and "connections" object
Step 2: ~~workflow_validate(workflow_json)
→ Check structure, node types, connections
→ If validation fails → see Error Handling below
Step 3: ~~workflow_create(workflow_json)
→ Creates the workflow on the instance
→ Set active: false (always import as inactive)
→ Returns the new workflow ID
Credential Reconfiguration
Credentials are NEVER transferred during import — this is by design for security.
After importing, guide the user through credential setup:
| Step | Action |
|---|---|
| 1 | Open the imported workflow in the n8n editor |
| 2 | Identify nodes with missing credentials (shown with warning icons) |
| 3 | For each node, select or create the appropriate credential |
| 4 | Use ~~credential_manage to list existing credentials that may already match |
| 5 | Test each credential connection before activating the workflow |
Common credential types encountered:
| Service Category | Typical Auth Method | Notes |
|---|---|---|
| Email (Gmail, Outlook) | OAuth2 | Requires browser-based authorization |
| Messaging (Slack, Discord) | OAuth2 or Bot Token | Bot tokens are simpler to set up |
| Databases (Postgres, MySQL) | Connection string | Host, port, user, password, database |
| APIs (REST, GraphQL) | API Key or Header Auth | Check the service's docs for key format |
| Cloud (AWS, GCP) | Access Key + Secret | Use IAM roles with least privilege |
Post-Import Verification
After a successful import, verify the deployment:
1. ~~workflow_list → confirm the new workflow appears
2. Compare node count:
→ Source JSON node count vs deployed workflow node count
→ Mismatch indicates dropped nodes — investigate
3. Check all connections are intact
4. Review any auto-fix changes applied during deploy
Activation Safety Protocol
Follow this sequence strictly:
- Import as inactive — never activate on import
- Configure credentials — link all required credentials
- Review trigger nodes — check webhook URLs, cron schedules, polling intervals
- Test manually — use n8n's "Test Workflow" button with sample data
- Activate — only after successful manual test
WARNING: Activating a workflow with webhook triggers immediately exposes those endpoints. Verify webhook paths do not conflict with existing workflows.
Error Handling
| Error | Cause | Resolution |
|---|---|---|
| Validation failure: unknown node type | Community node not installed | Install the required community node package first |
| Validation failure: invalid connections | Node IDs reference non-existent nodes | Re-map connections or remove broken references |
| Deploy timeout | Instance overloaded or unreachable | Retry after confirming instance health via ~~instance_audit |
| Duplicate workflow name | Name already exists on instance | Rename the workflow before import or append a numeric suffix |
| Missing community nodes | Workflow uses nodes not in the base install | List missing nodes, install them, then retry import |
| JSON parse error | Malformed source file | Validate the JSON structure before attempting import |
Decision Tree
Is the source an official n8n template ID?
├─ YES → Path 1: ~~template_get → ~~workflow_validate → ~~template_deploy
└─ NO
├─ Is it a raw JSON file or URL?
│ └─ YES → Path 2: fetch JSON → ~~workflow_validate → ~~workflow_create
└─ Is it a community forum/blog link?
└─ YES → Extract JSON from page → Path 2
