Installation
The script package can be installed using the package installer or manually.

GitHub
To install the api client, use this:

Code:
go get -u github.com/2captcha/2captcha-go
We invite you to explore our GitHub repository where you can find libraries and modules for easy integration with our API.


Configuration
Client instance can be created like this:

Code:
client := api2captcha.NewClient('YOUR_API_KEY')
You also have the ability to customize some of the options for the created instance:

Code:
client.SoftId = 123
client.Callback = "https://your.site/result-receiver"
client.DefaultTimeout = 120
client.RecaptchaTimeout = 600
client.PollingInterval = 100

Solve captcha
When you submit any image-based captcha use can provide additional options to help 2Captcha workers to solve it properly

Client instance options:

IMPORTANT: once callback is defined for Client instance, all methods return only the captcha ID and DO NOT poll the API to get the result. The result will be sent to the callback URL. To get the answer manually use getResult method

Code:
cap := api2captcha.Normal{
   File: "/path/to/normal.jpg",

code, err := client.Solve(cap.ToRequest())
if err != nil {
  if err == api2captcha.ErrTimeout {
    log.Fatal("Timeout");
  } else if err == api2captcha.ErrApi {
    log.Fatal("API error");
