Symfony RESTful API: Errors (Course 2)

Buy Access

In course 1, we added our basic endpoints with some nice tests (yes!).

Now, we turn to a huge part of APIs: handling and returning consistent errors. Seriously, this is more important than you might think - which is why we're covering this in episode 2.

So, let's handle errors, and let's do it gracefully:

  • Handling Form Validation errors and response
  • Disabling csrf_protection
  • Introducing the api-problem JSON format
  • Exception Listener!
  • Consistent errors everywhere: 404's, 500's, oh my!
  • Handling "extra fields" in your form

    Sorry, disregard! My fault. Please delete.

    Returns the following:


    "type": "validation_error",

    "title": "There was a validation error",

    "errors": [

    "The CSRF token is invalid. Please try to resubmit the form.",

    "Please enter a clever nickname"



    without the 'nickname' subelement.
