For the purposes of this thesis, an application was created that integrates theWord- Press CMS (content management system) with three social networks: Facebook, Twitter and LinkedIn. To achieve this integration, the user of the application must allow the application to operate on his behalf, and the application must store data related to authorization in a simple and reliable way, which was emphasized in this thesis. The database was created so that the authorization for all social networks is stored in the same table, which will in return simplify the potential addition of new social networks to the system. The primary goal of the application is to enable and automate the creation of textual content for content creators. The first key functionality is that every 24 hours the application automatically creates posts on social networks for which the user has given authorization, where these posts contain summaries of blogs published on the user’s WordPress site. Another key functionality is that the user can create text posts on all social networks connected to the application at the same time. The main obstacle in creating this thesis were the various restrictions placed on the REST APIs of used social networks and the fact that the documentation does not clearly highlight these restrictions and what endpoints are available for a certain access level that some user of the API has. Due to these limitations, not all of the planned functionalities could be realized, but the main functionalities work as intended. The application created for this thesis could be further worked on and additional functionalities could be implemented, for example integration with additional social networks (TikTok, Instagram, etc.) or adding the possibility of creating content in formats other than text (images, video). The problem, of course, are the restrictions placed on applications that integrate with social networks, and it is very likely that these restrictions will be tightened even more in view of the increasingly frequent measures to protect the privacy of users.
