is possible to write values to my website from an external program?

I’m able to read the content of my website page in my c++ program
And the page looks like:
https://cesarcaiooliveira.wixsite.com/cesar

Just a text, I wonder if is also possible to write values to it?
I’m new on Wix and on website programming, was searching about and I’m in doubt if it could be achieved using HTTP post

But i don’t understand whats next

See this example:

Expose and Access Site APIs
Use MyApi and MyApiClient to expose and access external APIs.

Someone else?

You will need to read about how to access 3rd party services in the article Corvid: How to Access 3rd-Party Services with the Fetch API .

A nice simple example to start with is Create a Weather Widget . Also, t ake a look at the Advanced examples , many of them access 3rd party services. A couple of good examples to start with are: Example: Using the Places API from Google Maps services and Example: Send email with the SendGrid REST interface .

For more information on how to expose an API, see the following:

I didn’t get it to work.
for example,
just an empty page like this:
https://cesarcaiooliveira.wixsite.com/cesar/page

with a text or something else, and I’m being able to fill the text content would help.
