Integration Steps of the Weatherstack API

Weatherstack API is one of the weather APIs that is most easily integrated into applications and projects in the market today. With its powerful infrastructure, the weatherstack API integrates with all major programming languages in just a few steps. In this section, we will integrate the weatherstack API into Golang, one of the most popular programming languages of recent times.

We need an API key to use the weatherstack historical weather API. For this, we need to sign up for one of the paid subscription plans it offers. We can see the API key we obtained after registration on the ‘dashboard’ page it provides.

After obtaining the API key, let’s now create a Golang file and put the following integration codes into it:

package main

import (

func main() {

  url := ""
  method := "GET"

  client := &http.Client {
  req, err := http.NewRequest(method, url, nil)

  if err != nil {
  res, err := client.Do(req)
  if err != nil {
  defer res.Body.Close()

  body, err := ioutil.ReadAll(res.Body)
  if err != nil {

With this code, we will obtain London’s historical weather data on 2020-01-09 from the weatherstack API’s historical weather data endpoint. Before running this code, let’s put our API key in the ‘API_KEY’ field and then run the application.

The JSON response we get milliseconds after running the application is as follows:
