I've created a post response callback from IPN, does $_POST['amount'] is an value or not, so i have to use converter with this amount to USD ?

        $ipn_type = $_POST['ipn_type'];
    	$txn_id = $_POST['txn_id'];
    	$item_name = $_POST['item_name'];
        $amount = $_POST['amount'];
    	$currency1 = $_POST['currency1'];
    	$currency2 = $_POST['currency2'];
    	$status = intval($_POST['status']);

is this correct, because i got an error saying that amount index does not exist.

thank you.

I'm attempting to integrate the CoinPayments API into my Next.js application using the coinpayments npm package. However, when I try to create a new transaction using the createTransaction method, I receive the following error:

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://www.coinpayments.net/api.php. (Reason: CORS header 'Access-Control-Allow-Origin' missing). Status code: 403.

I believe this error is related to Cross-Origin Resource Sharing (CORS) restrictions that prevent my Next.js application from making requests to the CoinPayments API. I've tried setting the mode option to no-cors when making the request, but this doesn't seem to resolve the issue.

Can you provide guidance on how to resolve this issue? Do I need to configure my server to allow cross-origin requests, or is there a way to configure the coinpayments package to handle CORS headers correctly?

Thanks for your help!

this object should be replaced with $information Variable

Is it possible with this library?

When I test it on localhost its working fine but when I uploaded it to the server it gives the following error message always-

Too many errors in the last two minutes from 2001:41d0:303:20a8:: please fix your code 
and try again

There is no way to obtain information on the minimum withdrawal of each currency.

I am trying to implement IPN notification on my server side .When i receive IPN on server , i am able to fetch request hmac from the request header but there is not data in body .
Server is in nodejs . i am taking reference from this example (https://www.coinpayments.net/downloads/cpipn.phps)
Sample code for my express server

const express = require('express')
const app = express()
const port = 8085;

app.get('/', (req, res) => res.send('Hello World! GET'));

app.post('/', (req, res) => res.send('Hello World! POST'));

app.get('/coinpaymentnotification', (req, res) => {
console.log("\nGET");
console.log(req.header);
console.log(req.headers);
console.log(req.body);
res.send('Hello World! GET');
});

app.post('/coinpaymentnotification', (req, res) => {
console.log("\nPOST");
console.log(req.header);
console.log(req.headers);
console.log(req.body);
res.send('Hello World! POST');
});

app.listen(port, () => console.log(`Example app listening at http://localhost:${port}`))

Output of those console statement :

POST
[Function: header]
{
  host: 'hostname',
  'user-agent': 'CoinPayments.net IPN Generator',
  accept: '*/*',
  hmac: 'hmacsendfromIPN',
  'content-type': 'application/x-www-form-urlencoded; charset=utf-8',
  'content-length': '378'
}
undefined

From reference example it seems i have to take body data and pass data and secret to hmac function for generating hmac .After generating hmac verify hmac with hmac send in request header .

1. Is i am doing something wrong in code ?
2. do i have to change some settings on coin payment account ?
3. is there any way i can test IPN on local system rather then live ?

The function does not provide a way to pass this POST attributes:

success_url, cancel_url

https://www.coinpayments.net/apidoc-create-transaction

// Check for success of API call
if ($cps_api['error'] == 'ok') {
    // Prepare start of sample HTML output
    $output = '<table><tbody><tr><td>Username</td><td>Merchant ID</td><td>Email</td><td>Public Name</td></tr>';
    $output .= '<tr><td>' . $cps_api['result']['username'] . '</td><td>' . $cps_api['result']['merchant_id'] . '</td><td>' . $cps_api['result']['email'] . '</td><td>' . $cps_api['result']['public_name'] . '</td></tr>';
    // Close the sample output HTML and echo it onto the page
    $output .= '</tbody></table>';
    echo $output;
} else {
    // Throw an error if both API calls were not successful
    echo 'There was an error returned by the API call: ' . $balances['error'] . '<br>Rates API call status: ' . $rates['error'];
}

$cps_api should be replaced by $information in the above code

1. The latest version on packagist is not up-to-date (missing autoload section in composer.json).
2. Even if I install current version with "composer require coinpaymentsnet/coinpayments-php" and then add "classmap": ["/src"] to vendor/coinpaymentsnet/coinpayments-php/composer.json classes are still not auto loaded by composer.

As a workaround I just added this to the root composer.json:

"classmap": [
  "vendor/coinpaymentsnet/coinpayments-php/src"
]

GetCallbackAddressWithIpn with an empty label returns the following error:

Error: The field "label" was passed but is not a valid field for the "get_callback_address" command!

A quick fix would be to only add the 'label' => $label key-value pair when it's not an empty string.

I have a doubt please clear it, How many addresses can be generated with GetOnlyCallbackAddress() or GetCallbackAddressWithIpn().

Actually, I want each of my users to have a single deposit address, what will happen if my user exceeds 3k or 10k or let's say 100k.

I'm afraid, duplicate addresses will be assigned! Can somebody let me know about its limit?
