WebMoney Check Captcha

I’m going to make it easier for users of my service to use WebMoney check by reducing the number of moves.
For this, I use the fields for sending on my site:
lmi_wmcheck_numberinside (check number)
lmi_wmcheck_codeinside (check password)
It also requires a captcha check (which was recently introduced), what field should be used to transfer it and where to load the captcha itself from?

Answer 1, authority 100%

Since WebMoney is a payment system, and they have increased security requirements, it is more appropriate to ask this question on their forum in the developer section.

Answer 2

And you can recognize the captcha using the pixodrom (.com) anti-captcha service
they ask for less than anti-gate – $ 1 for 1000 captchas. and there is a free test
