I've just realized that what people call Web Services, it is named "Joomla API" and the naming inconsistency is general.

Since "Joomla API" can refer to any API in Joomla (For instance, the Joomla Platform API), it would be great if we can avoid confusions naming web services as "Web Services". For more info about the definition of API as "application programming interface" https://en.wikipedia.org/wiki/API

Please, check the following inconsistencies between the official channels and the "Web Services" / "Joomla API" feature.

On Joomla 4, there are plugins named:

1. Web Services - Banners
2. API Authentication - Basic Auth
3. API Authentication - Joomla Token

In this case, it is not clear if all Joomla APIs of any kind are restricted with authentication, or only the Web Services are restricted with the "api-authentication" plugins.

So, it would be great if we settle to name web services as Joomla "Web Services" and remove all references to "Joomla API" or "API" to refer to "Web Services". In this way, the Joomla usage of the term "Web Service" will be close to the general usage of the concept. For more information about the "Web Service" term: https://en.wikipedia.org/wiki/Web_service
