I'm newer on powerapp. and i tried to create custom connector to access an API which have application/x-www-form-urlencoded params in body. please see below postman screen. the api need to be provided application/x-www-form-urlencoded data in body,
{
q: “xxx”,
format: csv
}
here is my swagger code
but when test this connector. The API returns 400 error because the body is empty.
