Here is a simple hello world API. Why isn't it working?

Are you receiving a 200 status when calling the endpoint?

I have installed your MLP into a local instance of Sugar. I made a basic GET call in Postman to {{url}}{{api_version}}/Hello/World/7 and my return result was "Hello World"

So i dont think there's anything wrong with your endpoint itself. I'm betting it has something to do with how you are calling it. I assume you are authenticating first and using the access_token. Otherwise, i'd think you would see at least some error message. Can you share with us your JS that is calling the endpoint?

I am calling the endpoint within the dashlet.(See custom/clients/base/views/hello-world-api/hello-world-api.js)  I assumed since I was calling it from with in the dashlet, I would not need to auth.

I see. sorry about that. i didnt look at the other files!

I believe the issue is that nothing is calling your loadData function.

Try adding this.loadData() to your initialize function.

I added this.loadData() to both the initialize2021.HelloWorldAPI.zip and render function and neither work.

You don't have to add a slash before app.api.buildURL - that will generate a double slash which might not work in some browsers.

Eg: Change app.api.buildURL('/Hello/World/1') to app.api.buildURL('Hello/World/1')

The first thing that I noticed is that: The success/failure function is outside of app.api.call. It has to be passed as the last argument so that it can be used as a callback.

ie:

app.api.call('GET', app.api.buildURL('/Hello/World/1'), null),
{
    success: function(data){
        if(this.disposed){
            return;
        }
        console.log(data);
    },
    error: function (e) {
        console.log('error');
        console.log(e);
   }
}

Should be changed to:

app.api.call('GET', app.api.buildURL('/Hello/World/1'), null,
{
    success: function(data){
        if(this.disposed){
            return;
        }
        console.log(data);
    },
    error: function (e) {
        console.log('error');
        console.log(e);
   }
});

This should fix your callbacks. The API definition looks correct.

Thank you both!!! It works now.

Is there a good tutorial to look at what the api is returning using postman?

I always refer to this tutorial which has a Postman cookbook which can be used to get/set access tokens:

sugarclub.sugarcrm.com/.../sugarcrm-cookbook---the-school-of-rest---part-1

I have created a  Hello World API package.  The API  sends Hello world and a number.  The Dashlet calls the API with the number and receives Hello World and the number and then it adds it to the dashlet inside the app.api.call() with _.extend.HelloWorldAPIv2.zip
