To install the api client, use this:
go get -u github.com/2captcha/2captcha-goImport the module like this:
import (
"github.com/2captcha/2captcha-go"
)Client instance can be created like this:
client := api2captcha.NewClient("YOUR_API_KEY")There are few options that can be configured:
client.SoftId = 123
client.Callback = "https://your.site/result-receiver"
client.DefaultTimeout = 120
client.RecaptchaTimeout = 600
client.PollingInterval = 100| Option | Default value | Description |
|---|---|---|
| soft_id | 4583 | Your software ID obtained after publishing in 2captcha software catalog |
| callback | - | URL of your web-sever that receives the captcha recognition result. The URl should be first registered in pingback settings of your account |
| default_timeout | 120 | Timeout in seconds for all captcha types except reCAPTCHA. Defines how long the module tries to get the answer from res.php API endpoint |
| recaptcha_timeout | 600 | Timeout for reCAPTCHA in seconds. Defines how long the module tries to get the answer from res.php API endpoint |
| polling_interval | 10 | Interval in seconds between requests to res.php API endpoint, setting values less than 5 seconds is not recommended |
IMPORTANT: once callback URL is defined for
clientinstance, 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
When you submit any image-based captcha use can provide additional options to help 2captcha workers to solve it properly.
| Option | Default Value | Description |
|---|---|---|
| numeric | 0 | Defines if captcha contains numeric or other symbols see more info in the API docs |
| min_len | 0 | minimal answer length |
| max_len | 0 | maximum answer length |
| phrase | 0 | defines if the answer contains multiple words or not |
| case_sensitive | 0 | defines if the answer is case sensitive |
| calc | 0 | defines captcha requires calculation |
| lang | - | defines the captcha language, see the list of supported languages |
| hint_img | - | an image with hint shown to workers with the captcha |
| hint_text | - | hint or task text shown to workers with the captcha |
Below you can find basic examples for every captcha type, check out the code below.
Example below shows a basic solver call example with error handling.
