Deleting a CAPTCHA

If you do not have the Yandex Cloud (CLI) command line interface yet, install and initialize it.

The folder specified when creating the CLI profile is used by default. To change the default folder, use the yc config set folder-id <folder_ID> command. You can specify a different folder using the --folder-name or --folder-id parameter.

1. See the description of the CLI command for deleting the CAPTCHA:

   yc smartcaptcha captcha delete --help
   

2. Get a list of captchas:

   yc smartcaptcha captcha list
   

   Result:

   +----------------------+---------+---------------------+------------+----------------+----------------+-------------+
   |          ID          |  NAME   |       CREATED       | COMPLEXITY | PRE-CHECK TYPE | CHALLENGE TYPE | RULES COUNT |

3. Delete the CAPTCHA by specifying its name or ID:

   yc smartcaptcha captcha delete <CAPTCHA_name_or_ID>

With Terraform, you can quickly create a cloud infrastructure in Yandex Cloud and manage it using configuration files. These files store the infrastructure description written in HashiCorp Configuration Language (HCL). If you change the configuration files, Terraform automatically detects which part of your configuration is already deployed, and what should be added or removed.

Terraform is distributed under the Business Source License. The Yandex Cloud provider for Terraform is distributed under the MPL-2.0 license.

For more information about the provider resources, see the documentation on the Terraform website or mirror website.

If you do not have Terraform yet, install it and configure its Yandex Cloud provider.

To delete a CAPTCHA created using Terraform:

1. Open the Terraform configuration file and delete the fragment with the yandex_smartcaptcha_captcha resource description:

   Example a CAPTCHA description in the Terraform configuration

   resource "yandex_smartcaptcha_captcha" "demo-advanced-smartcaptcha" {
     name                = "<captcha_name>"
     style_json          = "<captcha_appearance>"
     complexity          = "<challenge_difficulty>"
     pre_check_type      = "<main_challenge_type>"
     challenge_type      = "<additional_challenge_type>"
   
     allowed_sites = [
       "<first_host>",
       "<second_host>"
     ]
   
     # First challenge variant
     override_variant {
       uuid        = "<variant_1_ID>"
       description = "<variant_1_description>"
   
       complexity     = "<challenge_difficulty>"
       pre_check_type = "<main_challenge>"
       challenge_type = "<additional_challenge>"
     }
   
     # Second challenge variant 
     override_variant {
       uuid        = "<variant_2_ID"
       description = "<variant_2_description>"
   
       complexity     = "<challenge_difficulty>"
       pre_check_type = "<main_challenge>"
       challenge_type = "<additional_challenge>"
     }
   
     # First rule
     security_rule {
       name                  = "<rule_1_name>"
       priority              = <rule_1_priority>
       description           = "<rule_1_description>"
       override_variant_uuid = "<challenge_variant_ID>"
   
       condition {
         host {
           hosts {
             exact_match = "example.com"
           }
           hosts {
             exact_match = "example.net"
           }
         }
       }
     }
   
     # Second rule
     security_rule {
       name                  = "<rule_2_name>"
       priority              = <rule_2_priority>
       description           = "<rule_2_description>"
       override_variant_uuid = "<challenge_variant_ID>"
   
       condition {
         source_ip {
           geo_ip_match {
             locations = ["ru", "es"]
           }
         }
       }
     }
   }
   

2. Apply the changes:

   1. In the terminal, change to the folder where you edited the configuration file.

   2. Make sure the configuration file is correct using the command:

      terraform validate
      

      If the configuration is correct, the following message is returned:

      Success! The configuration is valid.
      

   3. Run the command:

      terraform plan
      

      The terminal will display a list of resources with parameters. No changes are made at this step. If the configuration contains errors, Terraform will point them out.

   4. Apply the configuration changes:

      terraform apply
      

   5. Confirm the changes: type yes in the terminal and press Enter.

   You can check the deletion of the resources using the management console or this CLI command:

   yc smartcaptcha captcha list
   

To delete a CAPTCHA, use the delete REST API method for the Captcha resource or the Captcha/Delete gRPC API call.
