Customer information_Lastname and currency not supported error on submission

@danieltobs firstly you need to change your currency from gravityforms settings , secondly to solve the redirection issues then you can try to use paystack callbacks to verify transaction cause it carrys back some params such as https://yoursite.com/?gf_paystack_return=aWRzPTZ8MXwxJmhhc2g9MTdhMjQ3YWY3YjRkODlhYzM4OTEwZjI1ZmI2ZDQ5YWM&trxref=gf-6-60e5ae3037337&reference=gf-6-60e5ae3037337

All you need to do is create a page called “/success” then go add this page on your paystack dashboard then download and activate code snippets plugin and paste the below code in the code snippets or your functions.php

function success(){
	
	$trxref = $GET['trxref'];

$curl = curl_init();
  
  curl_setopt_array($curl, array(
    CURLOPT_URL => "https://api.paystack.co/transaction/verify/:$trxref",
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_ENCODING => "",
    CURLOPT_MAXREDIRS => 10,
    CURLOPT_TIMEOUT => 30,
    CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
    CURLOPT_CUSTOMREQUEST => "GET",
    CURLOPT_HTTPHEADER => array(
      "Authorization: Bearer sk_live_YOUR KEYS",
      "Cache-Control: no-cache",
    ),
  ));
  
  $response = curl_exec($curl);
  $err = curl_error($curl);
  curl_close($curl);
  
  if ($err) {
    echo "cURL Error #:" . $err;
  } else {
    echo $response;
  }
}
add_shortcode('success','success');

Then add [success] shortcode to the page !
you then customize your response in the above code to get your json response as html
