Post request in API designer

please tell me if I’m using the API query designer correctly if I need to end up with a request, as in the example in the picture? (we discard the part with IP - it is not important). With this setup I always get an error in response. And if I write everything on the line after “?” and separating “&”, then there are no problems and the correct answer is returned

Request at your screen is using query parameters. But you try to configure URL parameters.
API Designer doesn’t support various types of payloads and can be used for JSON only. In your case you should configure this request directly in business process and use HTTP Request block.
Create model with all required fields (phone, ip, api_id) and set Serialize request body as Multipart form
