How do I use requestSuitelet to call a suitelet from Client Script without opening the Suitelet in a new window?

AI generated answer (using internal Slack threads):

To call a Suitelet from a Client Script without opening the Suitelet in a new window, you can use the

https

module's

get.promise

or

post.promise

methods. This allows you to make a GET or POST request to the Suitelet URL, and handle the response asynchronously. Here's a basic example of how you can do this:

javascript
var suiteletURL = url.resolveScript({
    scriptId: 'customscript_my_suitelet',
    deploymentId: 'customdeploy_my_suitelet',
    returnExternalUrl: true
});

https.get.promise({
    url: suiteletURL
}).then(function(response){
    var responseBody = JSON.parse(response.body);
    // handle response here
}).catch(function onRejected(reason){
    log.error({
        title: 'GET failed',
        details: reason
    });
});

In this example,

customscript_my_suitelet

and

customdeploy_my_suitelet

should be replaced with your Suitelet's Script ID and Deployment ID, respectively. The

returnExternalUrl

parameter is set to

true

to get the external URL of the Suitelet. The

https.get.promise

method returns a Promise that resolves with the response from the Suitelet. You can then handle the response in the

then

method. If the GET request fails for any reason, the

catch

method will be called with the reason for the failure. Please note that this method will only work if your Suitelet is set to be Available Without Login. If it's not, you'll need to include the appropriate authentication in your request. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
