SDK for PAY.nl allowing you to manage your PAY.nl transactions in nodeJS
npm install paynl-sdk --save- Import 'paynl-sdk' in your file.
- Register for a PAY.nl account at.
- In the PAY.nl admin panel, navigate to Manage -> Services and click the SL-code on the left.
- From the popup use the API token and service location ID, and configure them in the SDK.
Some of the basic examples are listed here, for the full list of examples, please take a look at the examples directory here.
All examples start with importing the paynl-sdk and creating a client using the AT token as username and the API token as password.
import{createPayNLClient}from'paynl-sdk';constpayNL=createPayNLClient({username: 'AT-####-####',password: '****************************************'});To fetch the configuration of a given service location. This can be used to create your own checkout.
constconfig=awaitpayNL.Service.getConfig('SL-####-####');Orders use the new Transaction Gateway Unit API. View the examples or online documentation for a complete overview of what is possible.
The most minimal request to create an order includes the service location ID and amount:
constorder=awaitpayNL.Orders.create({serviceId: 'SL-####-####',amount: {value: 1000,// in centscurrency: 'EUR',},});For testing purposes you may enable the sandbox mode:
constorder=awaitpayNL.Orders.create({serviceId: 'SL-####-####',amount: {value: 1000,// in centscurrency: 'EUR',},integration: {test: true,},});After an order is created you should store its ID, which you need to fetch or change it later on. To fetch an order or just its status:
constorderId='########-####-####-####-############';constorder=awaitpayNL.Orders.get(orderId);constorderStatus=awaitpayNL.Orders.status(orderId);This SDK can also add direct debit transactions. In order to do so, you need to create a mandate first.
constmandate=awaitpayNL.DirectDebit.createMandate({serviceId: 'SL-####-####',amount: {value: 1000,currency: 'EUR'},description: 'example description',type: 'FLEXIBLE',});constdirectDebit=awaitpayNL.DirectDebit.add({mandateId: mandate.code,processDate: newDate('2025-10-10'),description: 'Test direct debit',amount: {value: 1000,currency: 'EUR',},});Fetch a DirectDebit transaction to check the status.
constdirectDebit=awaitpayNL.DirectDebit.get('IO-####-####-####');
