API Connector: There was an issue setting up your call - Found

Hi all.
I’m from Russia. Paypal is not widely used and Stripe is not available in my country.
One of the most popular payment system in my country is Yandex.Merchant (YM).
So I need to make it possible for my clients to pay via YM.
Here is a documentation about what I need to send to YM: link with tech details.
So I created a new API call that is used as an action with method POST to
And four parameters: shopId, scid, sum, customerNumber.
When I initialise a call - I get a message: “There was an issue setting up your call - Found”.
What can be the reason of this error?

Best regards,


This message “found” is coming from the service. Can you check their documentation?
