I would like to have data from Magento 2 dashboard shown in some visualization software and have found documentation from the other site about their API, but I can't find any information from Magento to send data somewhere else. If possible, the data from Magento should be sent with a POST request to the other company's API.
Can anyone help med find documentation on how to send the data from Magento 2?
Have a look here magento 2 : How to use curl? and Magento 2 REST API usage with examples
for more details read this devdoc https://devdocs.magento.com/guides/v2.4/get-started/gs-curl.html
Magento doesn't provide a centralize way to make api REST call to external services.
I worked with multiple customers and it seems like developers always use their own REST implementation, using differents libraries on same project like Guzzle, Curl, Zend...
That's why I recommand you to use this module to industialize your REST API call through Guzzle library: https://github.com/zepgram/module-rest
