Hello, I'm starting to use the Rest Api, but from the begining I'm facing a problem with CORS.

Using javascript I'm able to get the token from https://mysite.com/imis/token

After that, I get the access_token for the subsequent calls, but it I do a simple call to https://mysite.com/imis/api/party/900111 I get this error in my browser Console

"Access to XMLHttpRequest at 'https://mysite.com/imis/api/party/900111' from origin 'http://localhost:4200' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource."

And this is the JavaScript code I'm trying to execute:

$.ajax("https://mysite.com/imis/api/party/900111",
{
type : "PUT",
contentType: "application/json",
data: JSON.stringify({ "$type": "Asi.Soa.Membership.DataContracts.PersonData, Asi.Soa.Membership.Contracts",

     "PersonName": { 
  
                  "$type": "Asi.Soa.Membership.DataContracts.PersonNameData, Asi.Soa.Membership.Contracts", 
  
                  "FirstName": "Peter", 
  
                  "LastName": "Carlton", 
  
                  "NamePrefix": "Mr."                
  
    
  
              }, 
  
     "PartyId": "900111"}), 
  
      dataType: "json", 

      crossDomain: true,
  
  headers: {
    "RequestVerificationToken": response.access_token,
    "Access-Control-Allow-Origin": "*",
    "Access-Control-Allow-Headers": "x-requested-with"
  }, 
  
  success: function(data){
    console.log(data);
  } 
  
  })       

Thank you!
