How to call a POST REST API from JQGrid?

 To call a POST REST API from JQGrid, you can use the ajaxGridOptions property of the grid configuration options to set the options for the jQuery ajax() function that is used to make the request. Here is an example code snippet that demonstrates how to call a POST REST API from JQGrid:

// Assuming the grid's ID is "myGrid"
$("#myGrid").jqGrid({
    // Other grid configuration options...
    url: "http://example.com/api/data",
    datatype: "json",
    mtype: "POST",
    colModel: [
        // Column definitions...
    ],
    ajaxGridOptions: {
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        type: "POST"
    },
    loadonce: true
});

In this example, we set the url property to the URL of the REST API and the datatype property to "json" to tell JQGrid to expect JSON data from the API. We also set the mtype property to "POST" to specify that we want to make a POST request to the API.

Next, we define the column model using the colModel property, which defines the columns of the grid. We also set the ajaxGridOptions property to an object that contains the options for the jQuery ajax() function that is used to make the request.

In this example, we set the contentType property to "application/json; charset=utf-8" to specify that we are sending JSON data in the request body. We also set the dataType property to "json" to tell jQuery to expect JSON data in the response. Finally, we set the type property to "POST" to specify that we are making a POST request.

When the user saves a row in the grid, JQGrid will serialize the data for the row into JSON and include it in the request body. JQGrid will then make a POST request to the specified URL with the serialized JSON data in the request body. You can customize the request body and other options based on the API you are using.
