Canvas API Deprecation

In the examples below, the deprecation dates should follow these rules:

The NOTICE date should be the date that the deprecation warning will first be visible in production.
To determine the EFFECTIVE date, add 90 days to the NOTICE date. If that day is a production release date, use that date. If that date is not a production release date, use the next production release date after that date.
Both dates should be formatted as YYYY-MM-DD.

API Method Deprecation

To deprecate an API method, use the @deprecated_method tag. You must provide a NOTICE date and an EFFECTIVE date for the deprecation, along with a description for the deprecation.

Deprecate a method with a replacement

ruby

# @deprecated_method NOTICE YYYY-MM-DD EFFECTIVE YYYY-MM-DD
#   A description of the deprecated method and why we're deprecating it.
#   Use {api:FooController#bar_action Foo#bar_action} instead.
def foo_action
end

def bar_action
end

Deprecate a method without a replacement

ruby

  # @deprecated_method NOTICE YYYY-MM-DD EFFECTIVE YYYY-MM-DD
  #   A description of the deprecated method and why we're deprecating it.
  def foo_action
  end

API Model Deprecation

To deprecate an API model, add the deprecated, deprecation_notice, deprecation_effective, and deprecation_description keys. These keys can be applied at the base model level to deprecate the entire model, or they can be applied at the property level to individually deprecate model properties.

Deprecate an entire API model

ruby

# @model Foo
#     {
#       "id": "Foo",
#       "description": "A description.",
#       "deprecated": true,
#       "deprecation_notice": "YYYY-MM-DD",
#       "deprecation_effective": "YYYY-MM-DD",
#       "deprecation_description": "A description of the deprecation.",
#       "properties": {
#         "bar": {
#           "description": "A property.",
#           "example": "baz",
#           "type": "string"
#         }
#       }
#     }

Deprecate an API model property

ruby

# @model Foo
#     {
#       "id": "Foo",
#       "description": "A description.",
#       "properties": {
#         "bar": {
#           "deprecated": true,
#           "deprecation_notice": "YYYY-MM-DD",
#           "deprecation_effective": "YYYY-MM-DD",
#           "deprecation_description": "A description of the deprecation.",
#           "description": "A property.",
#           "example": "baz",
#           "type": "string"
#         }
#       }
#     }

API Argument Deprecation

To deprecate an API argument, rename the @argument tag to @deprecated_argument. You must provide a NOTICE date and an EFFECTIVE date for the deprecation, along with a description for the deprecation.

Before:

ruby

# @argument foo [Required, String]
#   A description of the argument.

After:

ruby

# @deprecated_argument foo [Required, String] NOTICE YYYY-MM-DD EFFECTIVE YYYY-MM-DD
#   A description of the argument, along with a description of the deprecation.

API Response Field Deprecation

To deprecate an API response field, rename the @response_field tag to @deprecated_response_field. You must provide a NOTICE date and an EFFECTIVE date for the deprecation, along with a description for the deprecation.

Before:

ruby

# @response_field foo
#   A description of the response field.

After:

ruby

# @deprecated_response_field foo NOTICE YYYY-MM-DD EFFECTIVE YYYY-MM-DD
#   A description of the response field, along with a description of the
#   deprecation.
