Official JavaScript SDK to connect to the MyParcel API via Node.js or browser.


Install [@myparcel/sdk] with your package manager:

yarn add @myparcel/sdk
pnpm add @myparcel/sdk
npm install @myparcel/sdk

Usage examples

Basic usage

The client is Promise-based, so you can use async/await, or Promise.then.

First, instantiate an SDK and pass the endpoints you want to use.

import { createPrivateSdk, PostShipments } from '@myparcel/sdk';

const clientConfig = {
  headers: {
    Authorization: 'bearer ' + MY_BASE_64_ENCODED_API_KEY

const sdk = createPrivateSdk(new FetchClient(clientConfig), [
  new PostShipments(),

Then call the endpoint. There are constants available in our SDK for data like carriers, package types, delivery types and more. See constants

const result = await sdk.postShipments({
  body: [
      carrier: 1,
      options: {
        package_type: 'package',
      recipient: {
        cc: 'NL',
        city: 'Hoofddorp',
        person: 'Ms. Parcel',
        street: 'Antareslaan 31',

console.log(result); // [ 123456 ] (The ID of the shipment that was just created)

Using constants

Our SDK exposes some constants to make working with our API easier.

  • Carriers
    import { CARRIERS } from '@myparcelnl/sdk';
    CARRIERS.POSTNL_NAME // "postnl"
  • Package types: Contains all package types' names and IDs.
    import { PACKAGE_TYPES } from '@myparcelnl/sdk';
    PACKAGE_TYPES.LETTER // { ID: 3, NAME: "letter" }
    // etc
  • Delivery types
    import { DELIVERY_TYPES } from '@myparcelnl/sdk';
    DELIVERY_TYPES.MORNING // { ID: 1, NAME: "morning" }
    // etc
  • Countries: Contains constants for all countries, by name.
    import { COUNTRIES } from '@myparcelnl/sdk';
    // etc

Creating a new endpoint

To create a new endpoint, you can extend either AbstractPrivateEndpoint or AbstractPublicEndpoint and fill in the derived class as needed.

Feel free to add open a pull request to add it to our repository! See contributing.

Creating a new client

In this example we're creating an Axios client.

class AxiosClient extends AbstractClient {
  async request(endpoint, options) {
    try {
      const response = await axios.request({
        method: endpoint.method,
        url: this.createUrl(endpoint, options),
        headers: {

      return response.data;
    } catch (e) {
      return e.response.data;

Now use the new client with an SDK instance:

const sdk = createPublicSdk(new AxiosClient(), [new GetCarriers()]);

const carriers = await sdk.getCarriers();

console.log(carriers); // [ { "id": 1, "name": "postnl", (etc...)



Public endpoints do not require authorization and are safe to use in a browser.


Private endpoints require an Authorization header. This should be a base64 encoded MyParcel API key. You can create one in the shop settings in our [backoffice]. See [Authorization] in the API documentation for more information.
