Complete Node-by-Node Build Instructions

Step 1: Schedule Trigger Setup

1. Add a Schedule Trigger node as your starting point
2. Configure trigger settings:
   • Rule: Custom
   • Cron Expression: 0 */30 * * * * (checks every 30 minutes)
   • Timezone: Set to your target audience timezone
3. This node will regularly check for posts ready to publish

Step 2: Content Calendar Integration

1. Add a Google Sheets node after the Schedule Trigger
2. Configure the connection:
   • Operation: Read
   • Document: Select your content calendar spreadsheet
   • Sheet: Content Schedule
   • Range: A:F (adjust based on your columns)
3. Set up column mapping:
   • Column A: Post Date/Time
   • Column B: Caption Text
   • Column C: Image URL
   • Column D: Hashtags
   • Column E: Status (scheduled/published)
   • Column F: Post Type (feed/story)

Step 3: Filter Ready Posts

1. Add an IF node to filter posts ready for publishing
2. Configure conditions:
   • Value 1: {{$json["Status"]}}
   • Operation: Equal
   • Value 2: scheduled
3. Add second condition:
   • Value 1: {{DateTime.fromISO($json["Post Date/Time"]).diffNow().milliseconds}}
   • Operation: Less Than or Equal
   • Value 2: 0
4. Set Combine: AND
5. This ensures only scheduled posts due for publication proceed

Step 4: Image Processing

1. Add HTTP Request node for image download
2. Configure settings:
   • Method: GET
   • URL: {{$json["Image URL"]}}
   • Response Format: File
   • Download Binary Data: True
3. Add Cloudinary node for optimization
4. Configure Cloudinary:
   • Operation: Upload
   • Binary Property: data
   • Public ID: instagram_{{$json["id"]}}_{{DateTime.now().toFormat("yyyyMMdd_HHmmss")}}
   • Transformation: w_1080,h_1080,c_fill,q_auto,f_auto

Step 5: Instagram Media Creation

1. Add HTTP Request node for Instagram Graph API
2. Configure media creation:
   • Method: POST
   • URL: https://graph.facebook.com/v18.0/{{$vars.instagram_account_id}}/media
   • Send Body: True
   • Body Content Type: Form-Data
3. Set body parameters:
   • image_url: {{$json["secure_url"]}}
   • caption: {{$node["Google Sheets"].json["Caption Text"]}} {{$node["Google Sheets"].json["Hashtags"]}}
   • access_token: {{$vars.instagram_access_token}}

Step 6: Publish Instagram Post

1. Add another HTTP Request node for publishing
2. Configure publication:
   • Method: POST
   • URL: https://graph.facebook.com/v18.0/{{$vars.instagram_account_id}}/media_publish
   • Send Body: True
   • Body Content Type: Form-Data
3. Set body parameters:
   • creation_id: {{$json["id"]}}
   • access_token: {{$vars.instagram_access_token}}

Step 7: Update Content Calendar

1. Add Google Sheets node for status update
2. Configure update operation:
   • Operation: Update
   • Document: Same content calendar
   • Sheet: Content Schedule
   • Range: E{{$node["Google Sheets"].json["row_number"]}}
   • Values: [["published"]]
3. This marks the post as published to prevent duplicates

Step 8: Error Handling & Notifications

1. Add Slack or Email node connected to error output
2. Configure notification settings:
   • Channel: #social-media-alerts
   • Message: 🚨 Instagram posting failed for: {{$node["Google Sheets"].json["Caption Text"].substring(0, 50)}}...
   • Include Error Details: True
3. Add success notification branch:
   • Message: ✅ Successfully posted to Instagram: {{$json["permalink"]}}

Step 9: Analytics Logging

1. Add Google Sheets node for analytics tracking
2. Configure logging:
   • Operation: Append
   • Document: Analytics spreadsheet
   • Values:
     • Post ID: {{$json["id"]}}
     • Published Time: {{DateTime.now().toISO()}}
     • Caption Length: {{$node["Google Sheets"].json["Caption Text"].length}}
     • Hashtag Count: {{$node["Google Sheets"].json["Hashtags"].split("#").length - 1}}
