I do not see a way to post data to the headless CMS. Is this even possible?
What i want to achieve is allowing users to send data to EPiServer database, in order for them to retrieve it later.
You can use DDS to store any data that is not Episerver related. There are some articles that you can refer-
The Content Delivery API does not currently support POST or PUT of content.
What kind of content are you wanting users to save? You may need to roll your own API and storage repository.
Hi Martin, short answer: No. It is not possible to post data to Content Delivery API.
The API is about delivering content (and the API documentation just in case you have missed that link in the documentation).
So your option would be to create your own API to add "content" by the users (and I assume in this case with users you mean the users browsing the headless site and not the users who can login to Episerver edit mode and that way could add content to the system) and then you would be able to deliver that content from the Content Delivery API.
