I’m building an API and want Ajax to be able to interact with it.

  • 0

I’m building an API and want Ajax to be able to interact with it. The API needs to allow inserting, updating, and deletion of data. Is it a good idea to allow any of these operations via GET?

For example: http://api.domain.com/insert_person/?name=joe

My original plan way to use GET for my “getting” methods (basically, just a simple DB query) and POST for add, edit, and delete. Problem is JS same-origin policy which would make it hard for Ajax to interact with my API. There is a jQuery workaround for GET (via JSONP).

Suggestions?

    In a word: NO

    GET should always be used only for retrieving information and should never have side effects, ever.

    This is a best practice across just about every web api out there and has to do with both the intent of the verb as well as how existing software expects things to behave.
