Installation

Install via Composer.

$ composer require pdeans/miva-api

Configuring the Api Client

Utilizing the library to interact with the Api is accomplished via the Client class. The Client class accepts an array containing Api and HTTP client (cURL) configuration options in key/value format.

Client Configuration Options

Key	Required	Type	Description
url	Yes	string	The Api endpoint URL.
store_code	Yes	string	The Miva store code.
access_token	Yes	string	The Api access token.
private_key	Yes	string	The Api private key. Hint: If omitting signature validation, pass in an `''` empty string literal value.
hmac	No	string	HMAC signature type. Defaults to sha256. Valid types are one of: `sha256`, `sha1`, `''` (Enter a blank string literal if omitting signature validation).
timestamp	No	boolean	Enable/disable Api request timestamp validation. Defaults to true (Enabled).
http_headers	No	array	HTTP request headers. Note that the library will automatically send the `Content-Type: application/json` and `X-Miva-API-Authorization` headers with each Api request. For this reason, these headers should not be included in this list.
http_client	No	array	Associative array of curl options.

Example:

use pdeans\Miva\Api\Client;

$api = new Client([
    'url'          => 'https://www.domain.com/mm5/json.mvc',
    'store_code'   => 'PS',
    'access_token' => '0f90f77b58ca98836eba3d50f526f523',
    'private_key'  => '12345privatekey',
]);

// Example with Basic Authentication header and curl options
$api = new Client([
    'url'          => 'https://www.domain.com/mm5/json.mvc',
    'store_code'   => 'PS',
    'access_token' => '0f90f77b58ca98836eba3d50f526f523',
    'private_key'  => '12345privatekey',
    'http_headers' => [
        'Authorization' => 'Basic ' . base64_encode('username:password'),
        'Connection'    => 'close',
        'Cache-Control' => 'no-cache',
    ],
    'http_client' => [
        CURLOPT_SSL_VERIFYPEER => 0,
        CURLOPT_SSL_VERIFYHOST => 0,
    ],
]);

Authentication

The Miva Api authorization header will be automatically generated based on the configuration settings passed into the Client object and sent along with each Api request. The configuration settings should match the Miva store settings for the given Api token.

JSON Request Format

The required Miva_Request_Timestamp and Store_Code properties are automatically generated based on the configuration settings passed into the Client object and added to the JSON body for every Api request. The Function property is also automatically added to the JSON body for every request. The JSON data generated for the Function property will vary based on the provided request function list.

Function Builder

The func method is used to generate Api request functions. The method accepts the request function name as its only argument.

The add method is used to "publish" the function and append it to the request function list.

Note: All function builder methods are chainable.

$api->func('OrderCustomFieldList_Load')->add();

Function Request Parameters

This section showcases how to construct and add function parameters.

Common Filter List Parameters

Each common filter list parameter for the xxxList_Load_Query functions has a corresponding helper method to seamlessly set the parameter value. The example below shows each of the methods in action.

$api->func('OrderList_Load_Query')
    ->count(10)   // Limit number of records to return
    ->offset(5)   // Set offset of first record to return
    ->sort('id')  // Column sorting value
    // ->sort('-id')    // Column sorting value -descending
    // ->sortDesc('id') // Column sorting value with explicit descending
    ->filter('Customer_ID', 1850) // Add a filter
    ->add();

Function Request Filters

Most of the function search/display filters have an associated helper method that acts as a shorthand, or factory for creating the respective filter. The filter method must be used for any filter that does not have a linked helper method, as shown in the example above. This method can also be used to create each filter covered below. The method accepts two arguments, with the first argument always being the filter name. The second argument takes the filter value, which will vary per filter type.

The available search/display helper methods are covered below.

Search

The search method may be used to attach a search filter to a function's filter list. The most basic call to search requires three arguments. The first argument is the search field column. The second argument is the search operator, which can be any of the supported Api search operators. Finally, the third argument is the value to evaluate against the search column.

Below is an example to issue a search filter for a specific product code:

$api->func('ProductList_Load_Query')
    ->search('code', 'EQ', 'test-product')
    ->add();

For convenience, if you want to verify that a column is equal ('EQ') to a given value, you may pass the value directly as the second argument to the search method. The following will achieve the same result as the first example above:

$api->func('ProductList_Load_Query')
    ->search('code', 'test-product')
    ->add();

Of course, you may use a variety of other supported operators when writing a search filter:

$api->func('ProductList_Load_Query')
    ->search('active', 'FALSE')
    ->add();

$api->func('ProductList_Load_Query')
    ->search('price', 'GE', 2.20)
    ->add();

$api->func('ProductList_Load_Query')
    ->search('Category', 'IN', '13707,13708')
    ->add();

The search method can be issued multiple times to perform an AND search:

$api->func('ProductList_Load_Query')
    ->search('Category', 'IN', '13707')
    ->search('price', 'GT', 19.86)
    ->add();

Performing OR searches and parenthetical comparisons can be achieved by passing in an array to the search method as the first and only argument. The array should be modeled to match the desired search value output, with value nesting as needed:

// OR search
$api->func('OrderList_Load_Query')
    ->search([
        [
            'field'    => 'ship_lname',
            'operator' => 'EQ',
            'value'    => 'Griffin',
        ],
        [
            'field'    => 'ship_lname',
            'operator' => 'EQ',
            'value'    => 'Star',
        ],
    ])
    ->add();

// Parenthetical search
$api->func('OrderList_Load_Query')
    ->search([
        [
            'field'    => 'ship_lname',
            'operator' => 'EQ',
            'value'    => 'Griffin',
        ],
        [
            'field'    => 'search_OR',
            'operator' => 'SUBWHERE',
            'value'    => [
                [
                    'field'    => 'ship_fname',
                    'operator' => 'EQ',
                    'value'    => 'Patrick',
                ],
                [
                    'field'    => 'ship_lname',
                    'operator' => 'EQ',
                    'value'    => 'Star',
                ],
            ],
        ],
    ])
    ->add();

On Demand Columns

Using the ondemandcolumns method, you can specify the explicit columns to return. The method takes one argument, the list of on demand columns to select:

$api->func('ProductList_Load_Query')
    ->ondemandcolumns(['catcount', 'productinventorysettings'])
    ->add();

For convenience, the odc method can be utilized as an alias to the ondemandcolumns method:

$api->func('ProductList_Load_Query')
    ->odc(['catcount', 'productinventorysettings'])
    ->add();

Show

The "show" filters can be created using the show method. This method takes one argument, the show filter value, which will vary per xxxList_Load_Query function. Note that this filter is currently available for the following functions only:

CategoryList_Load_Query
CategoryProductList_Load_Query
ProductList_Load_Query

Example:

$api->func('ProductList_Load_Query')->show('Active')->add();

Function Request Input Parameters

Passphrase

The passphrase method is used to set the Passphrase parameter. The method takes a single argument, the decryption passphrase.

$api->func('OrderList_Load_Query')
    ->odc(['payment_data', 'customer', 'items', 'charges'])
    ->passphrase('helloworldhelloworld@123')
    ->add();

Additional Input Parameters

The params method is used to set all other input parameters. Some example use cases for this method are the request body parameters for the Xx_Create / Xx_Insert / Xx_Update / Xx_Delete functions, Module level functions, and essentially all other functions that require specific input parameters to perform actions. The function accepts a key/value array which maps to the input parameter key/values as its only argument.

Examples:

// Example: Create A New Product
$api->func('Product_Insert')
    ->params([
        'product_code' => 'new-product',
        'product_name' => 'New Product',
    ])
    ->add();

// Example: Update Product Inventory
$api->func('Product_Update')
    ->params([
        'product_code'      => 'new-product',
        'product_inventory' => 250,
    ])
    ->add();

// Example: Load An Order Queue
$api->func('Module')
    ->params([
        'Module_Code'     => 'orderworkflow',
        'Module_Function' => 'QueueOrderList_Load_Query',
        'Queue_Code'      => 'new_updated_orders',
    ])
    ->add();

// Example: Acknowledge An Order
$api->func('Module')
    ->params([
        'Module_Code'     => 'orderworkflow',
        'Module_Function' => 'OrderList_Acknowledge',
        'Order_Ids'       => [1000, 10001, 10002],
    ])
    ->add();

// Example: Create A Shipment
$api->func('OrderItemList_CreateShipment')
    ->params([
        'Order_Id' => '200103',
        'line_ids' => [100, 101],
    ])
    ->add();

// Example: Update Shipments
$api->func('OrderShipmentList_Update')
    ->params([
        'Shipment_Updates' => [
            [
                'shpmnt_id'    => 1,
                'mark_shipped' => true,
                'tracknum'     => '1234567890',
                'tracktype'    => 'UPS',
                'cost'         => 5,
            ], [
                'shpmnt_id'    => 2,
                'mark_shipped' => true,
                'tracknum'     => '0987654321',
                'tracktype'    => 'USPS',
            ],
        ],
    ])
    ->add();

API Requests

This section covers configuring and issuing Api requests.

HTTP Headers

You may specify which HTTP headers are attached to all Api requests with the addHeader and addHeaders methods. Please note that the library automatically creates and attaches the Content-Type: application/json and X-Miva-API-Authorization headers to each Api request.

// Add single header at a time
$api->addHeader('Custom-Header-Name', 'custom-header-value');
$api->addHeader('Cache-Control', 'no-cache');

// Add multiple headers in one swoop
$api->addHeaders([
    'Custom-Header-Name'=> 'custom-header-value',
    'Cache-Control'=> 'no-cache',
]);

Sending Requests

The send method will issue an Api request, and return the results in the library's Response object. If you wish to bypass this object and return the raw JSON response from the Api, pass a true value as the first argument for the send method.

Example requests:

// First add functions to request function list
$api->func('ProductList_Load_Query')
    ->search('code', 'prod1')
    ->add();

$api->func('CategoryList_Load_Query')
    ->sortDesc('id')
    ->count(5)
    ->filter('Category_Show', 'Active')
    ->add();

// Issue Api request - returns \pdeans\Miva\Api\Response object
$response = $api->send();

// Alternatively - returns raw JSON response
$response = $api->send(true);

You may preview the current request body at any time before sending the request by using the getRequestBody method. This is helpful for debugging requests.

echo '<pre>', $api->getRequestBody(), '</pre>';

API Responses

By default, Api responses will return a pdeans\Miva\Api\Response class instance. The Response object includes a number of helper methods for interacting with the Api responses.

Checking For Request Errors

Checking for errors that may have occurred on the Api request can be accomplished with the getErrors method. This method will return a stdClass object containing the error code and error message thrown. The isSuccess method returns a boolean value which can be used as a flag to determine if a request error occurred:

$response = $api->func('ProductList_Load_Query')->add()->send();
var_dump($response->getErrors());

if (!$response->isSuccess()) {
   echo 'Error: ', $response->getErrors()->message;
}

Response Body

The raw JSON response body can be retrieved anytime using the getBody method:

// Print raw JSON Api response
$response = $api->func('ProductList_Load_Query')->add()->send();
echo '<pre>', $response->getBody(), '</pre>';

To receive an iterable form of the Api response, issue the getResponse method. This will return an array of objects, with the array keys mapping to the function names supplied to the Api request function list. The items are sorted in identical order to the Api request function list. Each item or "function", contains its own array of the results of the function request. These array items correlate to each of the function's iterations that were sent in the request. The items are sorted in the same order that they were issued in the request. Use the getFunctions method to retrieve the list of available functions.

The getFunction method may be used to explicitly return the response results for a specific function name. This can also be accomplished with the getResponse method by passing the function name as the first argument.

The getData method returns the response data property for a specific function name. By default, the data property is returned for the first iteration index for the function name provided. However, an optional second argument can be provided to return the data property for a specific iteration index on the given function name.
