REST Adapter in its current version only publishes a single resource with a single verb in the inbound. Also, there can only be a single source within an integration flow. This is somewhat restrictive as the users have to create multiple integrations (each with a separate resource URI) for related resources and verbs.
Let's say someone has a requirement to create, update and delete a resource. Naturally, the expectation is that there would be a single resource which can be manipulated with different HTTP verbs. This is not possible with REST adapter and in the current version, users are forced to create multiple integrations for performing these different operations.
Pick is a solution to this. Have a look at how your pick integrations will look in canvas.
