REST API中的PUT和DELETE

Question

I have a question that still i have been using PUT and Delete in Web service (REST API) methods for respectively Update a resource and Delete a resource but i am informed now by mobile developers that its not good and always use POST method of HTTP to update and delete. Can i know how far is it true according to current world of technology ?

This is how i used.

Create -> Post
Read   -> Get
Update -> Put
Delete -> Delete

Suggest me the best API documentation that is available online with best practices.

Answer 1

I think the problem is mostly related to some browsers or JavaScript frameworks not properly passing DELETE and PUT on Ajax calls.

There's an overview of the --more or less-- current state for DELETE here:

Are the PUT, DELETE, HEAD, etc methods available in most web browsers?

and here (marked duplicate, but some different answers):

Which browsers don't support a HTTP DELETE with jQuery.ajax?

No mention of mobile browsers in particular, though.
