Picnic-API

Unofficial (unaffiliated) Node.js npm package for the API of the online supermarket Picnic.

Getting started

Using npm:

npm install picnic-api

Then import the package into your project. PicnicClient is the default export.

import PicnicClient from "picnic-api";

// or

const PicnicClient = require("picnic-api");

Now initialize the Picnic client with an optional options object.

const picnicClient = new PicnicClient();

// or

const picnicClient = new PicnicClient({
    countryCode: "NL", // The country code for the requests. Can be NL or DE. Untested for other countries.
    apiVersion: "17", // default 17 as this is what the app currently uses. The api version for the requests. Does not seem to do anything yet.
    authKey: "long string here", // default null. The code for the x-picnic-auth header to make authenticated requests. If not supplied then login() needs to be called before making any other requests.
    url: "url here" // default https://storefront-prod.nl.picnicinternational.com/api/17. The url to send requests to.
});

If no authKey was given in the options use the login method. Empty response if successful, otherwise an error.

await picnicClient.login("email", "password");
// send an authenticated request...

// or

picnicClient.login("email", "password").then(_ => {
    // send an authenticated request...
});

Example of a GET request:

let searchResults = await picnicClient.search("Affligem blond");

// or

picnicClient.search("Affligem blond").then(searchResults => {
    
});

Example of a POST request:

await picnicClient.addProductToShoppingCart(11295810, 2);

// or

picnicClient.addProductToShoppingCart(11295810, 2).then(shoppingCart => {
    
});

If you like this library then consider using my discount code MAAR3267 so that we both get a 5 euro discount on our orders. 😄

API Routes

Most API routes have been implemented as methods in the PicnicClient class. However, to get a list of all known API routes the method getKnownApiRoutes can be used. These routes are extracted from the Picnic android app. Latest extraction done for version 1.15.129.

Examples of a custom (unimplemented) request:

picnicClient.sendRequest(HttpMethods.GET, "/unknown/route");
picnicClient.sendRequest(HttpMethods.POST, "/invite/friend", { email: "[e-mail]" });
