Automated order confirmations with Abacate Pay: first-buyer coupon rewards via email & Slack

Workflow Overview This workflow provides a complete, automated post-purchase solution triggered by a successful payment webhook from Abacate Pay. (For international users, think of Abacate Pay as 'the Brazilian Stripe' – a popular and robust payment gateway in Brazil). When a successful payment is registered, this workflow instantly sends a beautiful, responsive HTML confirmation email to the customer and posts a detailed notification to a designated Slack channel. The key feature is its ability to dynamically reward first-time buyers. The workflow checks the customer's purchase history, and if it's their first order, it automatically generates a 10% discount coupon for their next purchase and includes it in the welcome email. Key Features: Webhook Trigger: Securely listens for successful payment events from Abacate Pay. First-Time Buyer Detection: Queries past orders to identify new customers. Automatic Coupon Generation: Creates a unique, single-use discount coupon for new buyers. Dynamic Content: The email and Slack messages automatically include the coupon details, but only for first-time buyers. Responsive HTML Email: Sends a professional and mobile-friendly order confirmation. Rich Slack Notifications: Uses Block Kit for well-formatted, actionable alerts for your team. Centralized Configuration: A single Configs node makes it easy to manage static variables like company name and tokens. Setup Instructions: 1. Webhook Node: Copy the webhook URL and paste it into your Abacate Pay dashboard for the "payment successful" event (e.g., billing.paid). 2. Configs Node: Open this Set node and fill in your company's information (companyName, companySite, companyEmail) and the token used to validate the webhook requests. 3. HTTP Request Nodes (GetOrders, CreateCustomCoupon): In both nodes, go to the "Authentication" or "Header" section and replace the placeholder Bearer Token with your actual Abacate Pay API key. 4. Send Email Node: Select your email credentials from the dropdown or configure a new account (e.g., SMTP, Gmail). 5. Slack Node: Select your Slack credentials and choose the channel where you want to receive notifications. 6. Activate the Workflow: Save and activate the workflow.
