node-red-contrib-btcpay 0.2.3

Node-RED nodes to talk to BTCPay Server

npm install node-red-contrib-btcpay

Node-RED nodes to interact with BTCPay Server.

Install

Run the following command in the root directory of your Node-RED instance:

npm install --save node-red-contrib-btcpay

Usage

This set provides 2 nodes:

  • btcpay-api - a BTCPay API client node. It makes API requests by sending msg.payload data to the specified API endpoint and outputs the response data as msg.payload.
  • btcpay-ipn - a BTCPay IPN listener node. It listens to BTCPay Instant Payment Notifications and outputs the invoice object as the msg.payload.

Configuration

You first need to create a new BTCPay store:

  1. Log in to your BTCPay Server instance
  2. Go to Stores menu
  3. Click on Create a new store
  4. Enter a name
  5. Push Create

Now you need to pair the client with your BTCPay store:

  1. Navigate to Stores > Settings > Access Tokens on your BTCPay Server
  2. Create a new token
  3. Leave PublicKey blank
  4. Request pairing
  5. Copy pairing code
  6. Open your Node-RED instance
  7. Drag & drop the btcpay api node from the palette to the workspace and double-click on it, to open the node editor
  8. In the Client dropdown menu pick the Add New btcpay-api-config option and press the pencil button at the right to add a new API configuration
  9. Enter the https URL to your BTCPay Server instance
  10. Paste the pairing code you copied on step 5
  11. Click the Pair client button - the private key and token fields will be automatically filled with your api credentials
  12. Push Update

Making API requests

To make requests using the btcpay-api node, set the http method and the url path to the API endpoint the node will call. These can be either specified in the node settings, or provided in msg.method (if the method is "via msg.method") and in msg.path (if the path is empty). The request body is the data in msg.payload.

After executing a request the node returns a message with the response data set to msg.payload.

Handling Instant Payment Notifications (IPN)

To receive Instant Payment Notifications with the btcpay-ipn node, set the url path the IPN listener will listen to notifications on.

When BTCPay Server sends a notification to the IPN listener url, it will trigger the node output with the invoice object set to msg.payload. Note: as the incoming data cannot be trusted, the node fetches the invoice data via API before the output.

Examples

Creating Invoices

This example enables to create an invoice with params specified in the "Invoice params" node by clicking the inject button. The "Invoice URL" node outputs the url of the new invoice to Debug window.
