Authentication

The Periodix Actions node authenticates with an API key from your Periodix Actions account. You create the key in the dashboard, then store it as an n8n credential.

Create an API key

1. Go to actions.periodix.net and log in, or create an account. A 3-day full-access free trial starts automatically.
2. Open the Profiles page and connect at least one LinkedIn account using the hosted auth flow.
3. Open the API keys page and click New API key.
4. Copy the generated key.

Connect a profile first

The node runs every action from a connected LinkedIn profile. Make sure at least one profile is connected before you run a workflow.

Add the credential in n8n

1. In n8n, create a new Periodix Actions API credential.
2. Paste the API key into the Access Token field.
3. Save the credential.

You can now select this credential on any Periodix Actions node.

Managing API keys

API keys are scoped to a single organization and can be revoked from the dashboard at any time. If a key is revoked, any n8n credential using it stops working: create a new key and update the credential.

The same API key also works for the MCP server and the REST API.

Next step

With authentication in place, configure the node.
