POST API request via function

Hello, In the cloud function, I try to make a POST API request, after which I need an appropriate response. And here is a strange situation - when I send a same request to the same API via POSTMAN or via a function from my local mobile application, I receive a correct response, while when the request is sent via cloud function, I receive the response status code 403 Forbidden. I was blocked by CORS policy when trying to send a request from a web application. Could this be the same type of problem? Could the problem is somewhere else?

TL;DR

The user is experiencing a 403 Forbidden error when sending a POST API request from a cloud function. They suspect it may be a CORS issue. Other users suggest checking the headers, comparing them to the headers used in Postman, and ensuring they are set correctly. One user suggests returning the headers in the JSON response for comparison. Another user provides an alternative code snippet for sending the request. No solution is provided in the thread.

What is the context? How do you run the request with what function on which environment?

I execute a cloud function, where the API request is placed.

Okay. So fetch inside node js deployed function ?

The function is properly deployed and execution status is completed. The request made to another API works fine, but it is clearly visible that in this case (API with CORS policy) there is a problem in Appwrite cloud function.

I understand But if you are using the node SDK that it's pretty not possible for it to meet CORS condition as the request is from a CLI and not from HTTP Can you share your code

I am using Dart SDK. Here is my code:

TypeScript

import 'package:http/http.dart' as http;
import 'dart:convert';
import 'package:dart_appwrite/dart_appwrite.dart';

Future<void> start(final req, final res) async {

var headers = {
  'Authorization': apiKey,
  'Content-Type': 'application/json'
};
var request = http.Request('POST', Uri.parse('https://api.myapi.com/v1/products'));
request.body = json.encode({
  "type": "Product",
  "name": "Gloves",
  "condition": "New",
  "code": "714",
  "imei": "714",
  "category": "",
  "model": "655954",
  "additionalModels": "",
  "status": "Active",
  "oneTimeUse": false,
  "inventoryControl": true,
  "TaxIncludedInCost": true,
  "cost": 0,
  "TaxIncludedInPrice": true,
  "price": 0,
  "enableOfferPrice": true,
  "offerStart": "15-Feb-2023 13:10",
  "offerEnd": "06-Mar-2024 13:44",
  "TaxIncludedInOfferPrice": true,
  "offerPrice": 5,
  "tax": 34513,
  "discountable": true,
  "description": "desc",
  "stockQuantity": 8
});
request.headers.addAll(headers);

http.StreamedResponse response = await request.send();

if (response.statusCode == 200 || response.statusCode == 201) {
 res.json({'res': await response.stream.bytesToString()});

  print(await response.stream.bytesToString());
}
else {
 res.json({'res': response.reasonPhrase});

}

}

So over here you get CORS?

over here I got 403 Forbidden

Ohh, So here you don't get CORS,

I would recommend you'll check the headers, that the

TypeScript

var headers = {
  'Authorization': apiKey,
  'Content-Type': 'application/json'
};

That they are exactly like in the postman For start return the header in the json

TypeScript

 res.json({
'res': response.reasonPhrase
'headers': headers
});

And compere them to the Postman one

Because so far you code looks intact

And I assume that you've redact the apiKey for the example, right?

Headers is the same. I copied the generated code snipped from POSTMAN to my cloud function. And that's right - apiKey is for example

It's really weird as CORS cannot occurs when running CLI, and the only problem is the 403 So, what I think can be the problem is that somehow your wanted API are blocking you server IP from any reason.
And just to prove it try this way instead of the one you're using (Which is how I send my requests)

TypeScript

import 'package:dart_appwrite/models.dart';
import 'package:http/http.dart' as http;
import 'dart:convert';
import 'package:dart_appwrite/dart_appwrite.dart';

Future<void> start(final req, final res) async {
  var headers = {
    'Authorization': apiKey,
    'Content-Type': 'application/json'
  };

  final data = {
    "type": "Product",
    "name": "Gloves",
    "condition": "New",
    "code": "714",
    "imei": "714",
    "category": "",
    "model": "655954",
    "additionalModels": "",
    "status": "Active",
    "oneTimeUse": false,
    "inventoryControl": true,
    "TaxIncludedInCost": true,
    "cost": 0,
    "TaxIncludedInPrice": true,
    "price": 0,
    "enableOfferPrice": true,
    "offerStart": "15-Feb-2023 13:10",
    "offerEnd": "06-Mar-2024 13:44",
    "TaxIncludedInOfferPrice": true,
    "offerPrice": 5,
    "tax": 34513,
    "discountable": true,
    "description": "desc",
    "stockQuantity": 8
  };

  try {
    var response = await http.post(Uri.parse('https://api.myapi.com/v1/products'),
      headers: headers,
      body: jsonEncode(data),
    );


    if (response.statusCode == 200 || response.statusCode == 201) {
      print(await response.body);

      // res.json({'res': await response.body});
    }
  } catch (e) {
    res.json({'res': response.reasonPhrase});
  }
}
