Authentication

Generate Token

To generate token, use this code:

require 'net/http'
require 'json'

url = URI("https://api.v1.test.nowpost.com/auth/token-generate")
http = Net::HTTP.new(url.host, url.port)
http.use_ssl = true

request = Net::HTTP::Post.new(url)
request["Content-Type"] = "application/json"
request.body = {
  email: "user@example.com",
  password: "your_password",
  secret_key: "your_secret_key"
}.to_json

response = http.request(request)
puts response.body


import requests

url = "https://api.v1.test.nowpost.com/auth/token-generate"
payload = {
    "email": "user@example.com",
    "password": "your_password",
    "secret_key": "your_secret_key"
}
headers = {
    "Content-Type": "application/json"
}

response = requests.post(url, json=payload, headers=headers)
print(response.json())


# With shell, you can just pass the correct header with each request
curl -X POST "https://api.v1.test.nowpost.com/auth/token-generate" \
-H "Content-Type: application/json" \
-d '{
  "email": "user@example.com",
  "password": "your_password",
  "secret_key": "your_secret_key"
}'


const axios = require("axios");

const url = "https://api.v1.test.nowpost.com/auth/token-generate";
const payload = {
  email: "user@example.com",
  password: "your_password",
  secret_key: "your_secret_key"
};

axios
  .post(url, payload, {
    headers: {
      "Content-Type": "application/json"
    }
  })
  .then(response => {
    console.log(response.data);
  })
  .catch(error => {
    console.error(
      "Error generating token:",
      error.response?.data || error.message
    );
  });

Make sure to replace email, password and secret with yours. The above request returns JSON structured like this:

{
  "access_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...",
  "refresh_token": "dGVzdC1yZWZyZXNoLXRva2Vu...",
  "token_type": "Bearer",
  "expires_in": 3600
}
