DeleteOrder

apiGroup

Orders

apiDescription

Remove an entire Order record from the database. This method will also remove the order-items along with their attributes and the order-total records. To see an example usage take a look at docs/REST/samples/order-service/remove_order.php

apiExample

{curl} Delete Order With ID = 400597 curl -X DELETE --user admin@example.org:12345 https://example.org/api.php/v2/orders/400597

apiSuccessExample

GetOrder

apiGroup

Orders

apiDescription

Get multiple or a single order record through a GET request. This method supports all the GET parameters that are mentioned in the "Introduction" section of this documentation.

Important: Whenever you make requests that will return multiple orders the response will contain a smaller version of each order record called order-list-item. This is done for better performance because the creation of a complete order record takes significant time (many objects are involved). If you still need the complete data of an order record you will have to make an extra GET request with the ID provided.

apiExample

{curl} Get All Orders curl -i --user admin@example.org:12345 https://example.org/api.php/v2/orders

apiExample

{curl} Get Order With ID = 400242 curl -i --user admin@example.org:12345 https://example.org/api.php/v2/orders/400242

apiExample

{curl} Search Orders curl -i --user admin@example.org:12345 https://example.org/api.php/v2/orders?q=DE

apiExample

{curl} Get Order's Items curl -i --user admin@example.org:12345 https://example.org/api.php/v2/orders/400573/items

apiExample

{curl} Get Order Item's Attributes curl -i --user admin@example.org:12345 https://example.org/api.php/v2/orders/400573/items/57/attributes

protected _getMappedControllerUri(IntType $index, array<string|int, mixed> $uri) : array<string|int, mixed>
Parameters
$index : IntType

Contains the URI position relative to the current controller.

$uri : array<string|int, mixed>

Contains the original URI

Return values
array<string|int, mixed> —

_initializePagingAndSortingFields()

Initialize pager and sorters fields.

protected _initializePagingAndSortingFields() : mixed

One of the common functionaries of the APIv2 is the pagination and sorting. The fields initialized by this method are helpers to facilitate the access to sort and pagination information

Return values
mixed —

_linkResponse()

Include links to response resources.

protected _linkResponse(array<string|int, mixed> &$response) : mixed

The APIv2 operates with simple resources that might be linked with other resources. This architecture promotes flexibility so that API consumers can have a simpler structure. This method will search for existing external resources and will add a link to the end of each resource.

IMPORTANT: If for some reason you need to include custom links to your resources do not use this method. Include them inside your controller method manually.

NOTICE #1: This method will only search at the first level of the resource. That means that nested ID values will not be taken into concern.

NOTICE #2: You can provide both associative (single response item) or sequential (multiple response items) arrays and this method will adjust the links accordingly.

Parameters
$response : array<string|int, mixed>

Passed by reference, new links will be appended into the end of each resource.

Return values
mixed —

_locateResource()

Add location header to a specific response.

protected _locateResource(string $p_name, int $p_id) : mixed

Use this method whenever you want the "Location" header to point to an existing resource so that clients can use it to fetch that resource without having to generate the URL themselves.

Parameters
$p_name : string
$p_id : int
Tags
throws
InvalidArgumentException

If the arguments contain an invalid value.

Return values
mixed —

_mapResponse()

Map the sub-resource to another controller.

protected _mapResponse(array<string|int, mixed> $criteria) : bool

Some API resources contain many subresources which makes the creation of a single controller class complicated and hard to maintain. This method will forward the request to a another controller by checking the provided criteria.

Example:

$criteria = array( 'items' => 'OrdersItemsAttributesApiV2Controller', 'totals' => 'OrdersTotalsApiV2Controller' );

Notice: Each controller should map a direct subresource and not deeper ones. This way every API controller is responsible to map its direct subresources.

Parameters
$criteria : array<string|int, mixed>

An array containing the mapping criteria.

Tags
throws
HttpApiV2Exception

If the subresource is not supported by the API.

Return values
bool —

Returns whether the request was eventually mapped.

_minimizeResponse()

Minimize response using the $fields parameter.

protected _minimizeResponse(array<string|int, mixed> &$response) : mixed

APIv2 supports the GET "fields" parameter which enables the client to select the exact fields to be included in the response. It does not support nested fields, only first-level.

You can provide both associative (single response item) or sequential (multiple response items) arrays and this method will adjust the links accordingly.

Parameters
$response : array<string|int, mixed>

Passed by reference, it will be minified to the required fields.

Return values
mixed —

_paginateResponse()

Paginate response using the $page and $per_page GET parameters.

protected _paginateResponse(array<string|int, mixed> &$response[, int $p_totalItemCount = null ]) : mixed

One of the common functionalities of the APIv2 is the pagination and this can be easily achieved by this function which will update the response with the records that need to be returned. This method will automatically set the pagination headers in the response so that client apps can easily navigate through results.

Parameters
$response : array<string|int, mixed>

Passed by reference, it will be paginated according to the provided parameters.

$p_totalItemCount : int = null

|null Optionally set the total number of resources.

Return values
mixed —

_prepareResponse()

[PRIVATE] Prepare response headers.

protected _prepareResponse() : mixed

This method will prepare default attributes of the API responses. Further response settings must be set explicitly from each controller method separately.

Not available to child-controllers (private method).

Return values
mixed —

_searchResponse()

Perform a search on the response array.

protected _searchResponse(array<string|int, mixed> &$response, string $p_keyword) : mixed

Normally the best way to filter the results is through the corresponding service but some times there is not specific method for searching the requested resource or subresource. When this is the case use this method to filter the results of the response before returning them back to the client.

Parameters
$response : array<string|int, mixed>

Contains the response data to be written.

$p_keyword : string

The keyword to be used for the search.

Tags
throws
InvalidArgumentException

If search keyword parameter is not a string.

Return values

_setPaginationHeader()

[PRIVATE] Set header pagination links.

protected _setPaginationHeader(int $p_currentPage, int $p_itemsPerPage, int $p_totalItemCount) : mixed

Useful for GET responses that return multiple items to the client. The client can use the links to navigate through the records without having to construct them on its own.

Parameters
$p_currentPage : int

Current request page number.

$p_itemsPerPage : int

The number of items to be returned in each page.

$p_totalItemCount : int

Total number of the resource items.

_setRateLimitHeader()

[PRIVATE] Handle rate limit headers.

protected _setRateLimitHeader() : mixed

There is a cache file that will store each user session and provide a security mechanism that will protect the shop from DOS attacks or service overuse. Each session will use the hashed "Authorization header" to identify the client. When the limit is reached a "HTTP/1.1 429 Too Many Requests" will be returned.

Headers: X-Rate-Limit-Limit >> Max number of requests allowed. X-Rate-Limit-Remaining >> Number of requests remaining. X-Rate-Limit-Reset >> UTC epoch seconds until the limit is reset.

Important: This method will be executed in every API call and it might slow the response time due to filesystem operations. If the difference is significant then it should be optimized.

Not available to child-controllers (private method).

Tags
throws
HttpApiV2Exception

If request limit exceed - 429 Too Many Requests

Return values

_sortResponse()

Sort response array with the "sort" GET parameter.

protected _sortResponse(array<string|int, mixed> &$response) : mixed

This method supports nested sort values, so by providing a "+address.street" value to the "sort" GET parameter the records will be sort by street value in ascending order. Method supports sorting up to 5 fields.

Important #1: This method has some advantages and disadvantages over the classic database sort mechanism. First it does not need mapping between the API fields and the database fields. Second it does not depend on external system code to sort the response items, so if for example a domain-service does not support sorting the result can still be sorted before sent to the client. The disadvantages are that it will only support a predefined number of fields and this is a trade-off because the method should not use the "eval" function, which will introduce security risks. Furthermore it might be a bit slower than the database sorting.

Important #2: This method is using PHP's array_multisort which by default will sort strings in a case sensitive manner. That means that strings starting with a capital letter will come before strings starting with a lowercase letter. http://php.net/manual/en/function.array-multisort.php

Example: // will sort ascending by customer ID and descending by customer company api.php/v2/customers?sort=+id,-address.company

Parameters
$response : array<string|int, mixed>

Passed by reference, contains an array of the multiple items that will returned as a response to the client.

Return values

_validateRequest()

[PRIVATE] Validate request before proceeding with response.

protected _validateRequest() : mixed

This method will validate the request headers, user authentication and other parameters before the controller proceeds with the response.

Not available to child-controllers (private method).

Tags
throws
HttpApiV2Exception

If validation fails - 415 Unsupported media type.

Return values

_writeResponse()

Write JSON encoded response data.

protected _writeResponse(array<string|int, mixed> $response[, int $p_statusCode = 200 ]) : mixed

Use this method to write a JSON encoded, pretty printed and unescaped response to the client consumer. It is very important that the API provides pretty printed responses because it is easier for users to debug and develop.

IMPORTANT: PHP v5.3 does not support the JSON_PRETTY_PRINT and JSON_UNESCAPED_SLASHES so this method will check for their existance and then use them if possible.

Parameters
$response : array<string|int, mixed>

Contains the response data to be written.

$p_statusCode : int = 200

(optional) Provide a custom status code for the response, default 200 - Success.

Return values
