n8n Authentication

The Probo n8n node authenticates using an API key sent as a Bearer token. You need to create credentials in n8n before using any Probo node.

Creating credentials

1. Add a Probo node to your workflow

   Search for “Probo” in the n8n node palette and drag it onto your canvas.

2. Open the credentials dialog

   Click the Credential dropdown in the node and select Create New Credential.

3. Configure the connection

   Field	Default	Description
   Probo Server	https://us.console.getprobo.com	Your Probo instance URL. Change this if you use a different region or self-host Probo.
   API Key	—	Your Probo API key

4. Test the connection

   Click Test to verify that n8n can reach your Probo instance and that the API key is valid. The node validates credentials by querying the authenticated user’s identity.

5. Save

   Click Save to store the credentials. They’ll be available to all Probo nodes in your workflows.

Getting an API key

You can generate an API key from the Probo console:

1. Go to Settings → API Keys in your Probo organization.
2. Click Create API Key.
3. Copy the key — it won’t be shown again.

Self-hosted instances

If you’re running a self-hosted Probo instance, set the Probo Server field to your instance URL (e.g., https://probo.internal.example.com). The node connects to the GraphQL API at /api/console/v1/graphql.
