2. Create an n8n Workflow

Step 1: Add a Trigger

• Choose how the workflow starts:

  3. Map fields like:
     • Title
     • Description
     • Image URLs
     • Tags

Step 3: Format the Data

• Use a Set Node to process or combine data:
  • Create a caption by combining the title and description.
  • Structure the data for your CMS or social media platforms.

Step 4: Post to a Website

• Add an HTTP Request Node or use a platform-specific node (e.g., WordPress):
  • For WordPress:
    • Method: POST.
    • Endpoint: https://yourwebsite.com/wp-json/wp/v2/posts.
    • Headers:jsonCopyEdit{ "Authorization": "Bearer YOUR_WORDPRESS_API_TOKEN" }
    • Body (JSON):jsonCopyEdit{ "title": "{{$json['title']}}", "content": "{{$json['description']}}", "status": "publish" }

  3. Map fields:
     • Image URL.
     • Caption.
