Datasource API

Hi Mario,
 
Thank you for writing to us.
 
You can further customize your requests using the customizeAPIRequest API call, which allows you to add additional requestHeaders to your request.
 
A detailed description of this functionality can be found by the following link: https://www.flexmonster.com/api/customizeapirequest/ 
 
Also, it might be helpful to check out our sample Node.js & .NET Core servers implementing the custom data source API for your reference. Please see them below:

.NET Core: https://www.flexmonster.com/doc/pivot-table-with-dot-net-core-server/ 
 
Please let us know if this helps.
 
Best regards,

Hi Mario,
 
Thank you for reporting this behavior.
 
We took a deeper look into this and realized there was indeed an issue with the JSFiddle & the provided documentation page.
 
In order for the headers to be displayed in the request, the request needs to be returned by the customizeAPIRequestFunction:
 

function customizeAPIRequestFunction(req) {
    req.requestHeaders = {
        "customHeader1": "This is the first custom request header",
        "customHeader2": "This is the second custom request header"
    };
    console.log(req);
    return req;
}

 
Please see the attached screenshot illustrating the results of this fix. Doing this will also fix the mentioned issue with requestBody, just as it works with the requestHeaders.
 
We've already updated the JSFiddle example correspondingly and will make sure to update the documentation as soon as possible.
 
Please let us know if you have any further questions we can help you with at the moment.
 
Best regards,
Mykhailo
