mercadopago.preferences.create()

[MustaCH]

Hi, I'm getting an error when executing my code, it tells me that mercadopago.preferences.create() is not a function. But everything I have seen has worked that way. Could you help me?

`const express = require("express");
const app = express();
const cors = require("cors");
const path = require("path");

const mercadopago = require("mercadopago");

new mercadopago.MercadoPagoConfig({
access_token:
"",
});

app.use(express.urlencoded({ extended: false }));
app.use(express.json());

app.use(express.static(path.join(__dirname, "../client")));
app.use(cors());

app.get("/", function (req, res) {
const filePath = path.resolve(__dirname, "..", "client", "index.html");
res.sendFile(filePath);
});

app.post("/create_preference", (req, res) => {
let preference = {
items: [
{
title: req.body.description,
unit_price: Number(req.body.price),
quantity: Number(req.body.quantity),
},
],
back_urls: {
success: "http://localhost:5500",
failure: "http://localhost:5500",
pending: "",
},
auto_return: "approved",
};

mercadopago.preferences
.create(preference)
.then(function (response) {
res.json({
id: response.body.id,
});
})
.catch(function (error) {
console.log(error);
});
});

app.get("/feedback", function (req, res) {
res.json({
Payment: req.query.payment_id,
Status: req.query.status,
MerchantOrder: req.query.merchant_order_id,
});
});

app.listen(5500, () => {
console.log("The server is now running on Port 5500");
});
`

I share the complete code so that you can take a look at it

Hi how are you?
It is likely that you have installed version 2 of the SDK and are implementing version 1.
The recommended option is to implement version 2, in your example there would be the following changes:

from

const mercadopago = require(“mercadopago”);

new mercadopago.MercadoPagoConfig({
access_token:
“”,
});

to

import { MercadoPagoConfig, Preference } from ‘MercadoPago’;

const client = new MercadoPagoConfig({ accessToken: ‘YOUR_AT’ });

and

let preference = {
        items: [
            {
                title: req.body.description,
                unit_price: Number(req.body.price),
                quantity: Number(req.body.quantity),
            },
        ],
        back_urls: {
            success: “http://localhost:5500”,
            failure: “http://localhost:5500”,
            pending: “”,
        },
        auto_return: “approved”,
    };

    mercadopago.preferences
        .create(preference)
        .then(function (response) {
            res.json({
                id: response.body.id,
            });
        })
        .catch(function (error) {
            console.log(error);
        });

to

const body = {
    items: [
        {
            title: req.body.description,
            unit_price: Number(req.body.price),
            quantity: Number(req.body.quantity)
        },
    ],
    back_urls: {
        success: “http://localhost:5500”,
        failure: “http://localhost:5500”,
        pending: “”
    },
    auto_return: “approved”
};

preference.create({
    ‘body’: body
}).then((result) => console.log(result))
    .catch((error) => console.log(error));
