说明与用途

本教程展示了如何将 n8n 与 Kelviq 集成，通过 WhatsApp 发送支付链接，接收支付完成的 Webhook，验证签名，并向客户通知支付成功或失败。

问题

How to accept payments inside an n8n workflow and notify customers via WhatsApp when the payment succeeds or fails.

结果

The workflow allows a WhatsApp bot to send a Pay Now button, automatically detect successful payments via Kelviq webhooks, and inform the customer of success or failure without requiring a custom server.

工作流

• Create a payment link by calling Kelviq’s checkout API via an HTTP Request node.
• Send the returned checkoutUrl to the customer through WhatsApp.
• Set up an n8n Webhook node to receive Kelviq’s checkout.completed event.
• Verify the webhook’s authenticity using the secret key and signature headers.
• If the webhook is valid, send a success message to the customer; otherwise, query Kelviq for the payment status and send a failure message.

证据

Kelviq handles the payment. n8n handles the steps. Webhooks connect the two.

Add a Code node after the Webhook node and paste this in. It checks the stamp using your secret key:
