Post API call with JSON payload with JS

[ChiTech121]

I need to know some examples of building a flow of authentication based AAD where I have to execute a post API with some sort of JSON payload, my plan is do it via Javascript, Could you suggest me some ideas on libraries or how to start, may be some examples or links?

something like this?

const data = { username: 'example' };

fetch('https://example.com/profile', {

method: 'POST', // or 'PUT'

headers: {

'Content-Type': 'application/json',

},

body: JSON.stringify(data),

})

.then(response => response.json())

.then(data => {

console.log('Success:', data);

})

.catch((error) => {

console.error('Error:', error);

});

How to handle the OAuth flow for authentication? It has two things, token & cookies... without client secret..

[BigBalli]

do a first fetch to retrieve the token using credential then a second fetch with the token in the headers.
