Let's consider a few examples based on two popular services for recognition captcha. 2Captcha - when you go to the page with the API description https://2captcha.com/2captcha-api#solving_normal_captcha, scrolling through the table below you can find a table where the parameters that can be specified  here is only a part of the possible parameters Anti-Captcha - there is also a table with valid parameters on the documentation page for solving simple text captchas  Even based on only these two services and only a small part of their parameters, you can see that

Directory - the directory where the pictures will be saved (you can use variables )
Answers - where to save answers to captchas:
The file name is convenient, but not always suitable, since Captchas may contain characters that cannot be used in file names in Windows -
\/:*?”<>|To file - when this setting is selected, a captcha picture with the name captcha (X) .png will be saved in the specified directory , where X is the serial number of the captcha. A captcha (X) .txt file will also be created in which the answer to this captcha will be. In this case, the system's restrictions on file naming will no longer be scary.
Ignore answer “sorry” - for some errors, the Recognize captcha action returns sorry instead of answering the captcha. When this option is enabled, the program will not save captchas with this answer.
Where it can be useful:
if you want to create your own module for the CapMonster Cloud service.
when using CapMonster 2 (a program for automatic captcha recognition) - this software has a lot of captchas that it supports, as they say, out of the box, but there are also some for which you need to create modules yourself. And to create a module, you need a database of correctly recognized captchas, and this is where these action settings come to the rescue - you recognize the captcha manually or using services, save the captchas and answers, and then use them to train CapMonster 2.

Quite often, especially on weakly protected resources, a text captcha is encountered. It differs from a simple (graphic) captcha in that it is not drawn in a picture, but simply written in text. In principle, such a captcha does not need to be sent anywhere, it can be taken (parsed) directly from the text of the page. To parse the captcha from the text of the page, you need to take the text of the page using the Data action, select the text of the page and, by marking "parse the result", enter a regular expression for parsing the page in the parameters.
...
There is also a mathematical text captcha. This is the same text captcha, only it is usually used to write a mathematical expression like 58 + 63. You can turn this text into a picture and send it for recognition, or you can use JavaScript. To recognize the captcha, you can use a JavaScript action from the Custom Code category. In the field for the code, you can insert a link to the variable that contains the parsed expression, for example 58 + 63, and after execution the action will return the result 121.
...
If you come across a flash captcha, you can turn it (render) into a regular picture and also send it for recognition. Find this element in the tree of elements , right-click to bring up the menu to select actions on this element. Select the item "This is a captcha" there ... that's it!
