It is possible to consume REST API using HTTP method PATCH.
Yet, when exposing PATCH method is not available. The only available HTTP methods are GET, POST, PUT, DELETE.
How can we expose a REST API method using PATCH?
Hi Joao,
11.12.0 version : You can now Expose REST webservices using the PATCH verb. This capability is a technical preview feature and you need to activate the option "PATCH method in exposed REST APIs" in LifeTime. (R11DT-89)
Like you already said, there's only get/post/put/delete, so "patch" is unfortunately not possible. I created an Idea for this a while ago, so please upvote it.
