Having trouble using 2captcha with Power Automate Desktop

Hi everyone, I'm kinda new to Power Automate, and I'm in the middle of building a flow with a captcha.

I've already failed with the OCR, and that's why I've started trying with 2captcha to get around this, but it seems that I've made some mistake in the conditionals to get it working alright.

I got the JavaScript function to work, but sadly I'm having trouble with the WebServiceResponse2 showing {"status":0,"request":"CAPCHA_NOT_READY"}, and thus printing "CAPCH" in the input text field as the captcha is for 5 characters only. I'm guessing the 10 second wait timer isn't working somehow or that I've messed up in the second Invoke web service?

I'm attaching some screenshots as well.

Hope you can help me fixing this flow.

I'm not familiar with the 2captcha service. Are you sure it is supposed to work with this specific captcha? If so, have you checked the documentation of 2captcha to check what to do when it returns this response?
Also, I would suggest not using Split text on a JSON response. Simply use Convert JSON to custom object and then access the values as properties of the object. Simply check if %JsonAsCustomObject['request']% = CAPTCHA_NOT_READY and if it is, retry.

Thanks for the asnwer Agnius!

Apparently I still need the split text to delete the delimiter character and give it the id needed to call the 2nd Invoke web service.

I finally managed to make it work though! Today I had an update in PAD and after installing and a lot of trial and error it seemed to me that the label RETRY I created and placed inside an the condicional If wasn't working if it wasn't placed outside the variable.

Lucky me 2captcha service worked with said captcha (though the ticket I created wasn't as satisfactory or fast as your answer though!), just seems that sometimes takes a couple extra seconds than the 5 they ask if the status of the request hasn't changed to 1.

Also i cleaned little the big If I had created and made them into separated conditionals, looking like this:
Once again, thanks for your fast reply!

Labels and the Go to action are bugged in PAD for a while now. They do not work properly in some situations. I would usually suggest using a While loop with 1=1 condition (infinite loop) and then use Exit loop when your condition is satisfied (you would need to reverse the condition though - make it exit the loop when you have achieved success).

I would also like to note that your current condition in the second If block will likely never be satisfied. You are comparing a part of the response (the 'request' part) with a JSON that includes more than just the part. You should do %JsonAsCustomObject['request']% = CAPTCHA_NOT_READY as suggested previously.
