Can anybody help me to getting start with joplin server api. I don't know how do I start anybody help me?
There's no server API as far I know. What exactly are you trying to do?
It's undocumented for now, but if you have a specific question I might be able to help.
I want to make a note taking app with joplin api and I want to perform basic CRUD operations and I think you have data api which have endpoints can anybody help me how I use it?
Joplin Server is not specifically for note taking, it's a cloud file storage like Nextcloud or Dropbox.
To see how it works, you could open JoplinServerApi.ts and set debugRequests_ to true.
