n8n

Connect your n8n instance by saving its base URL and your own API key, after checking they actually work together. Create the key in your instance: Settings -> n8n API -> Create an API key. Works for both self-hosted n8n and n8n Cloud -- just paste your instance's own URL, there's no auto-detection since n8n has no fixed set of hosts the way Make.com does.

Disconnect n8n: deletes the saved base URL and API key. Existing workflows/executions on your own n8n instance are untouched.

Check whether n8n is currently connected (does not reveal the saved base URL or API key).

List workflows on your connected n8n instance -- name, active state, and tags. Supports filtering by active state and/or tags.

Read one n8n workflow in full -- its nodes, connections, and active state.

Create a brand-new workflow on your n8n instance from an explicit node/connection definition (n8n's own workflow JSON format).

Update an existing n8n workflow's name, nodes, and/or connections. n8n's PUT /workflows/{id} replaces the whole entity, so this reads the current workflow first and merges in only the fields you gave.

Permanently delete a workflow from your n8n instance. Cannot be undone.

Publish (activate) an n8n workflow so its triggers start running. This is n8n's current API -- the older activate/deactivate endpoints are deprecated.

Unpublish (deactivate) an n8n workflow so its triggers stop running.

Run an n8n workflow right now by id. This endpoint is recent in n8n's own API (added late 2025) -- older self-hosted instances may not have it; if it fails, trigger the workflow via its own Webhook node URL instead.

List past/current executions on your connected n8n instance -- status, workflow, and timing. Filter by status and/or workflow id.

Read one n8n execution in full, optionally including its run data.

Permanently delete one n8n execution record. This does not affect the workflow itself -- only its execution history.

Retry a failed n8n execution.

Stop one currently-running n8n execution.

Stop several currently-running n8n executions at once.

List credentials stored on your connected n8n instance -- name and type only, never their secret field values (n8n's own API never returns those either).

Read the field schema for one n8n credential type (e.g. 'openAiApi') -- which fields it needs -- before creating a credential of that type.

Create a new credential on your connected n8n instance. WARNING: this stores sensitive data (API keys, passwords, tokens) on your n8n instance -- only do this for credentials you intend workflows to use. n8n has no update endpoint: to change a credential later you must delete it and create it again.

Permanently delete a credential from your connected n8n instance. Workflows using it will fail until re-configured. This is also the only way to 'change' a credential -- n8n has no update endpoint, so delete this one and create_n8n_credential a replacement.

List tags defined on your connected n8n instance.

Create a new tag on your connected n8n instance.

Rename a tag on your connected n8n instance.

Permanently delete a tag from your connected n8n instance. Workflows keep working -- they just lose this tag.

Read the tags currently assigned to one n8n workflow.

Replace the full set of tags assigned to one n8n workflow (pass every tag id that should remain, not just the ones to add).

List the saved version history of one n8n workflow.

Read one specific saved version of an n8n workflow in full.

Unarchive a previously archived n8n workflow, making it visible and editable again.

Move an n8n workflow to a different project (Enterprise/multi-project instances only).

Read the tags currently assigned to one n8n execution.

Replace the full set of tags assigned to one n8n execution.

Read one credential's metadata (name, type, timestamps) -- never its secret field values, which n8n's API never returns after creation.

Update a credential's name and/or its field values on your connected n8n instance. WARNING: this stores sensitive data -- only use when you trust the source of the new values.

Test whether a credential's stored values still work against its target service.

Move a credential to a different project (Enterprise/multi-project instances only).

List variables defined on your connected n8n instance -- named key/value pairs any workflow can reference via $vars.

Create a new instance-wide variable on your connected n8n instance.

Update an existing variable's value on your connected n8n instance.

Permanently delete a variable from your connected n8n instance. Workflows referencing it will get an empty value at runtime.

List users on your connected n8n instance. Only meaningful on multi-user (Enterprise) instances -- self-hosted single-owner instances will just show the one owner account.

Invite one or more new users to your connected n8n instance by email. Enterprise feature -- fails on Community edition instances.

Read one user's profile on your connected n8n instance, by id or email.

Permanently delete a user from your connected n8n instance. Their workflows and credentials are NOT deleted -- transfer ownership first if needed.

Change a user's global role on your connected n8n instance (e.g. 'global:admin', 'global:member').

Pull the latest changes from the connected remote Git repository into your n8n instance (Environments/Source Control feature -- Enterprise).

Generate a security audit report for your connected n8n instance -- flags risky nodes, exposed credentials, outdated workflows, and more.
