Check out this guide to learn how to configure the ‘HTTP Request’ module for launching a workflow with Captain Data in n8n:

​
Prerequisites

Before setting up the module, ensure you have a data source in place. This could be:
  • A CRM (e.g., HubSpot)
  • A spreadsheet (e.g., Google Sheets)
  • Notion
  • A workflow launched from Slack
Captain Data does not natively support triggering a workflow when a new row is added to a spreadsheet. To achieve this, use n8n’s Google Sheets Trigger Module (rowAdded).

n8n Nodes Setup

​
1. Import the Blueprint

Copy and paste the following JSON into n8n to create your workflow: 
{
  "name": "My workflow 2",
  "nodes": [
    {
      "parameters": {},
      "type": "n8n-nodes-base.manualTrigger",
      "typeVersion": 1,
      "position": [0, 0],

      "name": "When clicking ‘Test workflow’"
    },
    {

            }
          ]
        },
