Picnic-API

Unofficial Node.js wrapper for the API of the Picnic online supermarket. Not affiliated with Picnic.

Installation

npm install picnic-api

Quick start

Import the package and create a client. All configuration options are optional.

import PicnicClient from "picnic-api";

const picnicClient = new PicnicClient({
  countryCode: "NL", // The country code for the API. Options: "NL" (default), "DE" or "FR".
  authKey: "...",    // An existing auth key to skip the login step.
  apiVersion: "15",  // The API version (defaults to "15").
  url: "...",        // A custom base URL (defaults to https://storefront-prod.<countryCode>.picnicinternational.com/api/<apiVersion>).
  deviceId: "...",   // Custom device identifier for x-picnic-did header. (defaults to "3C417201548B2E3B")
  agent: "...",      // Custom agent string for x-picnic-agent header. (defaults to "30100;1.228.1-15480;")
});

Authentication

Most endpoints require authentication. Call auth.login() to obtain an auth key, which is automatically stored in the client and sent with subsequent requests. If you already have a key from a previous session, pass it as authKey in the constructor instead.

If the login endpoint responds with a 2FA requirement (second_factor_authentication_required: true), then call auth.generate2FACode("SMS") to generate a 2FA code and pass it to auth.verify2FA(<code>) to complete the login process.

await picnicClient.auth.login("email", "password");

// If 2FA is required:
await picnicClient.auth.generate2FACode("SMS");
await picnicClient.auth.verify2FA("123456");

Usage examples

// Search for products
const results = await picnicClient.catalog.search("Affligem blond");

// Add a product to the cart
await picnicClient.cart.addProductToCart(11295810, 2);

// Bulk add products to the cart
await picnicClient.cart.addProductsToCart([
  { productId: "s11295810", quantity: 2 },
  { productId: "s10000123", quantity: 1 },
]);

// Get available delivery slots
const slots = await picnicClient.cart.getDeliverySlots();

// Get details of a specific delivery
const delivery = await picnicClient.delivery.getDelivery("delivery-id");

Custom requests

For endpoints not yet covered by a domain service, use sendRequest directly:

await picnicClient.sendRequest("GET", "/unknown/route");
await picnicClient.sendRequest("POST", "/invite/friend", { email: "friend@example.com" });

API reference

The client exposes the following domain services, each grouping a set of related endpoints:
