Get request in SSJS on cloudpage results in 500 error

Question

I'm attempting to send some data via a GET request in SSJS on a CloudPage. The code below is throwing a 500 server error. I'm assuming that means there's something wrong with the syntax but I can't figure out what that would be.

This is what my API documentation says the request should look like, and I guess I'm just having trouble converting it to the format of the SSJS function:

GET /WS/Interaction.asmx/IssueInteractionUserDefined?WSSecurityToken=string&MemberAccountId=string&SBInternalMemberId=string&InteractionTypeExternalReference=string&LocationExternalReference=string&InteractionNote=string HTTP/1.1
Host: app.domain.com

var email = Request.GetQueryStringParameter("e");
var url = 'https://app.domain.com/WS/Interaction.asmx/IssueInteractionUserDefined';
var interaction = 'Dec2021-Survey';
var headers = ['WSSecurityToken','MemberAccountId','SBInternalMemberId','InteractionTypeExternalReference','LocationExternalReference','InteractionNote'];
var values = ['token',email,'-1',interaction,'Sales_Force',''];
var response = HTTP.Get(url, headers, values);
Write(response.Status + '<br />');
Write(response.Content);

Error Message:

"An error occurred when attempting to evaluate a HTTPGet function call. See inner exception for details.\r\n ClientID: 6252256\r\n JobID: 0\r\n ListID: 0\r\n BatchID: 0\r\n SubscriberID: 0\r\n URL: https://app.domain.com/WS/Interaction.asmx/IssueInteractionUserDefined\r\n"

HTTP GET passes the information via Query String - like you see in your example. (the part after the ?). So what you are sending via the headers in the Http.Get function is incorrect and likely causing the error.

You will need to append all these values to your URL like the example.

E.g.

?WSSecurityToken=string&MemberAccountId=string&SBInternalMemberId=string&InteractionTypeExternalReference=string&LocationExternalReference=string&InteractionNote=string

will be added on to the base url you have. You just add in the variables to the appropriate places in the URL.
