    • The GlideHTTPRequest API provides utility methods to perform common functions with Glide HTTP requests.

    You can use this API in global server-side scripts. To use this class, instantiate a GlideHTTPRequest object using the constructor. The constructor requires an endpoint URL as an input parameter.

    GlideHTTPRequest - addHeader(String name, String value)

    Adds a header to your HTTP request.

    Tableau 1. Parameters
    Name Type Description
    name String Header name, such as Accept or Content-Type.
    value String Header value, such as application/json.
    Tableau 2. Returns
    Type Description
    void

    This example adds the request header "Accept" and returns the number of the incidents from a ServiceNow Instance, parsing the JSON or XML responses.

    var instance = 'dev12345';
var username = 'admin';
var password = 'yourpassword';

// Instantiate request with ServiceNow API incidents table endpoint
var request = new GlideHTTPRequest('https://'+instance+'.service-now.com/api/now/table/incident');

// Add authentication data
request.setBasicAuth(username, password);

// Add the Accept header to get JSON response
request.addHeader('Accept', 'application/json');

// Execute the GET request
var response = request.get();

// Print the results: status code and number of records returned
gs.print(response.getStatusCode());
gs.print('(JSON) Incidents returned: ' + JSON.parse(response.getBody()).result.length);

// Replace the Accept header to get XML response
request.addHeader('Accept', 'application/xml');

// Execute the GET request
var response = request.get();

// Print the results: status code and number of records returned
gs.print(response.getStatusCode());
gs.print('(XML) Incidents returned: ' + gs.xmlToJSON(response.getBody()).response.result.length);

    Output

    200
(JSON) Incidents returned: 66
200
(XML) Incidents returned: 66

    GlideHTTPRequest - addParameter(String name, String value)

    Adds a parameter to your HTTP request.

    void

    This example shows how to add the sysparm_limit parameter to the REST endpoint call to limit the number of returned responses.

    var instance = 'dev12345';
var username = 'admin';
var password = 'yourpassword';

// Instantiate request with ServiceNow API incidents table endpoint
var request = new GlideHTTPRequest('https://'+instance+'.service-now.com/api/now/table/incident');

// Add authentication data
request.setBasicAuth(username, password);

// Add the 'sysparm_limit' parameter to limit the number of records returned
request.addParameter('sysparm_limit', 1);

// Execute the GET request
var response = request.get();

// Print the results: status code and number of records returned
gs.print(response.getStatusCode());

    Output:

    200
Incidents returned: 1
