GoHighLevel Custom Fields from Google Sheets | Slack Alerts

Bulk-create GoHighLevel custom fields from Google Sheets—with Slack error alerts

This n8n workflow reads your GoHighLevel (LeadConnector) business custom field definitions from Google Sheets, creates only the fields that aren’t marked as done, and notifies your team in Slack if anything fails.

What this workflow does

• Manual trigger: Start by clicking “Execute workflow” in n8n.
• Uses Google Sheets as the source of truth: Reads the “Accounts Custom Fields” tab from Google Sheets and pulls columns such as Field Name, Suggested Field Type, key, Status, ID, Location ID, and Parent Field ID.
• Fetches existing fields in GoHighLevel: Retrieves current business custom fields via the GoHighLevel (LeadConnector) API to avoid duplicates.
• Processes only UNDONE rows: Loops through each row and continues only when Status is “UNDONE”.
• Creates fields in bulk: For each eligible row, creates the business custom field in GoHighLevel using the provided field name, data type, key, location ID, and parent field ID.
• Writes results back to Google Sheets: Updates the sheet with the created field ID and changes Status to Done; if creation fails, marks the row as Error.
• Slack alerts on execution errors: Sends a message to your selected Slack channel whenever the workflow hits an execution error.

Use cases

• Standardize GoHighLevel custom field creation across multiple client/location setups.
• Ship new account/contact attributes by updating a Google Sheet, then running the workflow.
• Reduce setup time for SaaS operators managing repeated GoHighLevel configurations.
