n8n CLI

The n8n-cli command-line tool manages an n8n instance via its REST API. It auto-detects piped output and switches to JSON, making it composable for scripts and LLM tool use.

Setup

# Interactive login (saves to ~/.n8n-cli/config.json)
n8n-cli login

# Or configure directly
n8n-cli config set-url https://my-instance.n8n.cloud
n8n-cli config set-api-key n8n_api_...

# Or use environment variables (no config file needed)
export N8N_URL=https://my-instance.n8n.cloud
export N8N_API_KEY=n8n_api_...

Global Flags

Every command supports these flags:

FlagShortDescription
--url-uInstance URL (overrides config/env)
--apiKey-kAPI key (overrides config/env)
--format-fOutput format: table, json, id-only
--jsonShorthand for --format=json
--jqjq-style filter (implies --json), e.g. '.[0].id', '.[].name'
--quiet-qSuppress output
--no-headerHide table headers (for awk/cut parsing)
--debugPrint HTTP details to stderr

Auto-JSON: When stdout is piped (not a TTY), output defaults to JSON automatically.

n8n-cli workflow create --file=workflow.json
cat workflow.json | n8n-cli workflow create --stdin

# Update a workflow
n8n-cli workflow update <id> --file=updated.json
cat updated.json | n8n-cli workflow update <id> --stdin

# Activate / deactivate
n8n-cli workflow activate <id>
n8n-cli workflow deactivate <id>

# Delete a workflow
n8n-cli workflow delete <id>

# Transfer to another project
n8n-cli workflow transfer <id> --project=<projectId>

# List tags on a workflow
n8n-cli workflow tags <id>

Executions

# List recent executions
n8n-cli execution list
n8n-cli execution list --workflow=<id> --status=error --limit=10
# status options: canceled, error, running, success, waiting

Promotions

Move projects between instances through a Git repository. A provider holds the credentials, a connection names the repository, and a configuration sets up one direction on it: promote pushes to Git, apply imports from Git.

# 1. Create a provider. An SSH provider returns a public key to add as a deploy key.
#    The response carries the provider fields at the top level, so `.id` and
#    `.publicKey` both work with --jq and --format=id-only.
echo '{"name":"GitHub","type":"git","auth":{"authType":"ssh-key","keyType":"ed25519"}}' \
  | n8n-cli promotion-provider create --stdin --json > provider.json
jq -r '.id' provider.json          # use as providerId in step 2
jq -r '.publicKey' provider.json   # add to the repository as a deploy key

# 2. Create a connection on that provider, with the directions you need.
#    Leave out "configs" to configure no direction yet.
n8n-cli promotion-connection create --file=connection.json

# 3. Clone each direction before you use it.
n8n-cli promotion-connection clone <id> promote
n8n-cli promotion-connection clone <id> apply

# 4. Promote from this instance, or apply to it.
n8n-cli promotion-connection promote <id> -m "Promote team projects"
n8n-cli promotion-connection apply <id>

Apply a reviewed commit only:

# Review the changes. Take the commit SHA from the same response as the rows:
# a second request can read a newer commit.
n8n-cli promotion-connection list-changes <projectId> apply --sort=updatedAt --order=desc --json > reviewed-changes.json
jq '{commitSha, changes}' reviewed-changes.json
# The config ID and branch come from the connection.
n8n-cli promotion-connection get <id> --jq '.configs.apply.id'
n8n-cli promotion-connection get <id> --jq '.configs.apply.settings.branchName'

n8n-cli promotion-connection apply <id> \
  --expected-config-id=<configId> --expected-branch=<branch> --expected-commit-sha=<full sha>
# Exit 3: the source changed since the review. Review again.
# Exit 4: preflight found missing bindings, access requirements, or conflicts. Resolve them,
# then run the apply-continue command that apply printed:
n8n-cli promotion-connection apply-continue <id> \
  --expected-config-id=<configId> --expected-branch=<branch> --expected-commit-sha=<full sha>

Connection JSON for step 2:

{
  "name": "Production",
  "scope": "instance",
  "providerId": "prov-1",
  "target": { "schemaVersion": 1, "remoteUrl": "git@github.com:acme/flows.git" },
  "configs": {
    "promote": {
      "settings": {
        "schemaVersion": 1,
        "baseBranchName": "main",
        "createBranchOnPromotion": false
      }
    },
    "apply": { "settings": { "schemaVersion": 1, "branchName": "main" } }
  }
}
# Providers
n8n-cli promotion-provider list
n8n-cli promotion-provider get <id>          # re-read the public key; the list omits it
echo '{"name":"New name"}' | n8n-cli promotion-provider update <id> --stdin
n8n-cli promotion-provider delete <id>       # fails while a connection uses it

# Connections
n8n-cli promotion-connection list --scope=instance
n8n-cli promotion-connection list --provider=<providerId>
n8n-cli promotion-connection get <id>
echo '{"name":"New name"}' | n8n-cli promotion-connection update <id> --stdin
n8n-cli promotion-connection delete <id>

# Change one direction. The write replaces the whole configuration,
# so send every setting you want to keep.
echo '{"settings":{"schemaVersion":1,"branchName":"main"}}' \
  | n8n-cli promotion-connection set-config <id> apply --stdin
echo '{"settings":{"schemaVersion":1,"baseBranchName":"main","createBranchOnPromotion":false}}' \
  | n8n-cli promotion-connection set-config <id> promote --stdin
n8n-cli promotion-connection delete-config <id> apply
n8n-cli promotion-connection disconnect <id> promote

# Link projects to a "projects"-scoped connection
n8n-cli promotion-connection list-projects <id>
n8n-cli promotion-connection add-project <id> <projectId>
n8n-cli promotion-connection remove-project <id> <projectId>

Key points:

  • Pass every JSON body through --stdin or --file, never through a flag. This keeps credentials off the command line.
  • authType is ssh-key or token. token means an HTTP(S) username and password, not a Git host API token. publicKey is null for a token provider.
  • createBranchOnPromotion is always required in a promote configuration.
  • promote and apply work on the instance connection only, and need their direction cloned first. Cloning one direction does not make the other ready.
  • apply and apply-continue import nothing on exit code 3 (source-changed) or 4 (blocked). Check $?, or the status field in JSON output, before you read counts. With --json, a blocked result lists what is missing under preflight.
  • The --expected-* flags go together: pass all three or none. The commit SHA must be the full SHA.
  • API key scopes for this group are named gitConnection:*. promote also needs variable:list when the workflows reference variables.

Composability Patterns

The CLI is designed to be piped and composed:

# Get all workflow IDs
n8n-cli workflow list --jq '.[].id'

# Get the name of the first workflow
n8n-cli workflow list --jq '.[0].name'

# Export a workflow to a file
n8n-cli workflow get 1234 --json > workflow-backup.json

# Find failing executions for a workflow
n8n-cli execution list --workflow=1234 --status=error --json

# Pipe workflow JSON for modification
n8n-cli workflow get 1234 --json | jq '.name = "Updated Name"' | n8n-cli workflow update 1234 --stdin

# Table output without headers for shell parsing
n8n-cli workflow list --no-header | awk '{print $1}'

# Debug API calls
n8n-cli workflow list --debug 2>debug.log

Workflow JSON Structure

When creating or updating workflows, the JSON follows this structure:

{
  "name": "My Workflow",
  "nodes": [
    {
      "name": "Start",
      "type": "n8n-nodes-base.manualTrigger",
      "position": [250, 300],
      "parameters": {}
    },
    {
      "name": "HTTP Request",
      "type": "n8n-nodes-base.httpRequest",
      "position": [450, 300],
      "parameters": {
        "url": "https://api.example.com/data",
        "method": "GET"
      }
    }
  ],
  "connections": {
    "Start": {
      "main": [[{ "node": "HTTP Request", "type": "main", "index": 0 }]]
    }
  }
}

Key points:

  • nodes[].type follows the pattern n8n-nodes-base.<nodeName> for built-in nodes
  • connections is keyed by source node name, with main output arrays
  • Each connection specifies target node, type (usually main), and output index
  • Use workflow get <id> --json to see real examples from the instance
