Poli CREATE Nodes are responsible for creating new records within the system, such as apps, webhooks, tags, and contacts.
Unlike the LIST nodes (which return lists) and the GET nodes (which provide details of existing records), the CREATE nodes are used to insert new data that will later be used in automations.

Prerequisites

Before using any creation node, you need to have the following parameters on hand:

• Access Token → obtained in this tutorial.
• Account UUID → obtained via List Accounts.
• Application UUID → obtained via List Apps.
• Tag UUID → obtained via List Tags (if you want to link tags when creating a contact).

Available CREATE Nodes in n8n

Currently, there are 4 main creation nodes. See how each one works and which fields are required:

1. Create App

Function: Creates a new application in the account, used for integrations, webhooks, and tokens.
Required parameter: Account UUID.
Mandatory fields:

• App name
• Description
• Responsible person’s name
• Phone number (with area code)
• Email
  Optional fields:
• picture_file_id (image linked to the app).

2. Create Webhook

Function: Creates a new webhook linked to an application.
Required parameter: Application UUID.
Mandatory fields:

• Webhook URL (address that will receive the events)
• Subscriptions (which events the webhook should listen to, e.g., messages, contacts, status).

3. Create Tags

Function: Creates a new tag within the company.
Required parameter: Account UUID.
Mandatory fields:
