ApiGility - Getting validation errors with PUT - zend-framework

Question

I am new to ApiGility and am attempting to update my shopping cart via an API call as apposed to a route. I am using Zend Framework 2 with a code connected api.
The problem I am currently facing is that no matter what I try, I am unable to put the information to the api without validation errors.
My module.config:
Updatecart settings:
'Api\\V1\\Rest\\Updatecart\\Controller' => array(
'listener' => 'Api\\V1\\Rest\\Updatecart\\UpdatecartResource',
'route_name' => 'api.rest.updatecart',
'route_identifier_name' => 'updatecart_id',
'collection_name' => 'updatecart',
'entity_http_methods' => array(
0 => 'GET',
1 => 'PATCH',
2 => 'PUT',
3 => 'DELETE',
),
'collection_http_methods' => array(
0 => 'GET',
1 => 'POST',
2 => 'PUT',
3 => 'PATCH',
4 => 'DELETE',
),
'collection_query_whitelist' => array(
0 => 'prod_id',
1 => 'quantity',
2 => 'quantity_accumulation',
3 => 'tax',
),
'page_size' => 25,
'page_size_param' => null,
'entity_class' => 'Api\\V1\\Rest\\Updatecart\\UpdatecartEntity',
'collection_class' => 'Api\\V1\\Rest\\Updatecart\\UpdatecartCollection',
'service_name' => 'updatecart',
),
Relevant filter settings:
'Api\\V1\\Rest\\Updatecart\\Validator' => array(
0 => array(
'name' => 'prod_id',
'required' => true,
'filters' => array(
0 => array(
'name' => 'Zend\\Filter\\Int',
'options' => array(),
),
),
'validators' => array(),
'description' => 'The id of the product in the cart to be updated',
'error_message' => 'Missing product id',
'allow_empty' => false,
'continue_if_empty' => false,
),
1 => array(
'name' => 'quantity',
'required' => true,
'filters' => array(),
'validators' => array(),
'description' => 'quantity of product',
'error_message' => 'You must include a quantity',
'allow_empty' => false,
'continue_if_empty' => false,
),
2 => array(
'name' => 'tax',
'required' => true,
'filters' => array(),
'validators' => array(),
'description' => 'Add the VAT, GST, Sales Tax that will be applicable to this item. Use 0.00 for no value.',
'error_message' => 'Please add a tax value, 0.00 for no value.',
'allow_empty' => false,
'continue_if_empty' => false,
),
3 => array(
'name' => 'quantity_accumulation',
'required' => true,
'filters' => array(
0 => array(
'name' => 'Zend\\Filter\\Boolean',
'options' => array(),
),
),
'validators' => array(),
'description' => 'Either accumulate the entered quantity to the current basket quantity or set as the entered quantity.',
'allow_empty' => false,
'continue_if_empty' => false,
'error_message' => 'Quantity accumulation field error.',
),
),
When calling the PUT method:
https://cloud.mysite.dev:8890/api/updatecart/1?prod_id=1&quantity=1&update_type=1&tax=0.00
I keep getting Failed Validation errors:
{
"validation_messages": {
"prod_id": [
"Missing product id"
],
"quantity": [
"You must include a quantity"
],
"tax": [
"Please add a tax value, 0.00 for no value."
],
"quantity_accumulation": [
"Quantity accumulation field error."
]
},
"type": "http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html",
"title": "Unprocessable Entity",
"status": 422,
"detail": "Failed Validation"
}

You need to supply your data as http body (payload) in json format.
Make the call to the URI without the query params.
https://cloud.mysite.dev:8890/api/updatecart/1
{
"prod_id": 1,
"quantity": 1,
"update_type": 1,
"tax": "0.00"
}
Also make sure you supply the right request headers:
Accept: application/json
Content-Type: application/json
