request-promise not recognizing the URI when it is stated in the option object - http

Question

I have a method that should return a response from another server. I use request-promise and put the URL in the options object.
As you can see in the code below, all is in good shape, but when I send the request, it returns 404 - resource not found.
When I change the request(options) method with request("https://api.quickpay.net/payments"), I get a positive answer from the server -- it tells me to add headers and so forth, which is positive.
public requestNewQuickpayPayment(order_id: String, currency : String, callback: Function) {
var options = {
method: 'POST',
uri: 'https://api.quickpay.net/payments',
form:{
order_id : "order123",
currency : "dkk"
},
headers: {
"Content-Type" : "application/json",
'Accept-Version': 'v10'
},
json: true
};
request(options).then((response:any)=>{
console.log(response);
return response;
}).catch((error:any)=>{
console.log(error);
return error;
}).finally(()=>{
console.log("done");
})
}
Something from the console

What is wrong here? The path to the ressource is checked many times - nothing is wrong there....

Answer 1

For api.quickpay.net, 404 Not Found does not mean the URI is not recognized, but indicating invalid request body. It has nothing to do with whether the URI is stated in options object, or stated as string parameter of request().
Here is a simple experiment. The code below would return "positive" result, warning missing headers ({"error":"Accept-Version http header is required"}), which indicates that the URI is "recognized":
request({
method: 'POST',
uri: 'https://api.quickpay.net/payments'
}, function(err, res, body) {
console.log(body);
});
However, after the missing Accept-Version header is added, we get 404 Not Found:
request({
method: 'POST',
uri: 'https://api.quickpay.net/payments',
headers: {
'Accept-Version': 'v10'
}
}, function(err, res, body) {
console.log(body);
});
Thus, in order to make the API call work, you need to make the HTTP request valid (following to the document).
