correios-api-client

A Node.js client for the Correios API, allowing for easy integration and management of various Correios services such as Token, Price, Deadline, CEP, and Tracking.

Installation

npm install correios-api-client

Usage

Firstly, you need to initialize the API client with your configuration.

const apiClient = require('correios-api-client');

const configuration = {
    ambiente:  "PRODUCAO",
    idCorreios: "00000000",
    codigoAcesso:  "xxxxxxxxxxxxxx",
    contrato:  "000000000",
}

apiClient.initialize(configuration);

Authentication

Authenticate with the Correios API to receive tokens.

const token = await apiClient.Token.autentica();
const tokenCartaoPostagem = await apiClient.Token.autenticaCartaoPostagem();
const tokenContrato = await apiClient.Token.autenticaContrato();

CEP Lookup

Search for an address by CEP or retrieve multiple addresses.

const endereco = await apiClient.Cep.search("85070555");
const enderecos = await apiClient.Cep.searchMany(["85070555", "85070200"]);

Delivery Timeframe

Calculate the delivery timeframe for national packages.

const prazo = await apiClient.Prazo.nacional("04014", "85070555", "85070200");

Tracking

Track parcels using the tracking number.

const rastro = await apiClient.Rastro.search("LX697446262CN");

Price Estimation

Get the estimated price for a package delivery.

const consultaPreco = {
    alturaCm: 20,
    cepDestino: "85070555",
    cepOrigem: "85070222",
    comprimentoCm: 20,
    diametroCm: 0,
    tipoObjeto: TiposObjeto.Pacote,
    larguraCm: 20,
    pesoEmGramas: 300,
    codigoProduto: "03220",
    isAvisoRecebimento: false,
    isMaoPropria: false,
    valorDeclarado: 200
};

const preco = await apiClient.Preco.nacional(consultaPreco);
