Build n8n AI Automation: Webhooks, API Integrations & CRM Workflow Setup

Project Details: Build one functional n8n automation workflow that connects a webhook with Airtable and an email service to automate payment logging and email receipt delivery. Project Requirements: 1. Create one n8n workflow for receiving payment information through a webhook. 2. Process and validate essential payment details, such as customer name, email, transaction ID, and amount. 3. Store payment records in Airtable. 4. Generate a basic HTML email receipt using the payment information. 5. Send the receipt automatically to the customer's email address. 6. Configure the required API credentials and connections using client-provided accounts. 7. Add basic conditional logic to handle missing or invalid information. 8. Include basic error handling for failed workflow steps. 9. Test the workflow using sample payment data. 10. Provide the exported n8n workflow JSON and basic setup instructions. The final solution should demonstrate a working automation that connects webhooks, Airtable, and email delivery without requiring a large, multi-system enterprise workflow.
