Tesco Price Update

v1.0		Hristiyan Georgiev	Initial version

Just like the Stock update we need to update variant by variant. We are practically using the same GraphQL mutation, the only difference is in the variables.

All triggers, validations etc are as per the abstraction - Price Update General requirements

GraphQL Query

mutation VariantUpdate($input: VariantUpdateMutationInput!) {
    variantUpdate(input: $input) {
        variant {
          id
            displayable        
        }
        errors {
            field
            messages
        }
    }
}

Query Variables:

{
    "input": {
        "variantId": "VmFyaWFudC0xMDU2MTA=", 
        "attributes": {
                "price": 100,
          "salePrice": 79
        }
    }
}

Variables mapping:

Integration Field			Hemi Mapping	Hemi Notes
`input`
	`variantId`		`Product Account` `Tesco` > `Variant ID`
	`attributes`
		`price`	`Product Account` > `RRP`	We need to have a validation and if we have `RRP` less than or equal to `Price` we need to return an internal error as Tesco would not allow this. The `RRP` always has to be higher than the `Price`. If we don’t have RRP at all in Hemi, we just exclude it from the payload.
		`salePrice`	`Product Account` > `Price`	We need to have validation and we should not be able to send negative price or price equal to 0

Example Success Response :

{
    "data": {
        "variantUpdate": {
            "variant": {
                "id": "VmFyaWFudC0xMDU2NDI=",
                "displayable": true
            },
            "errors": null
        }
    }
}

Example Error Response :

{
    "data": {
        "variantUpdate": {
            "variant": null,
            "errors": [
                {
                    "field": "sale_price",
                    "messages": [
                        "must be greater than or equal to 0"
                    ]
                }
            ]
        }
    }
}

We don’t need to map anything from the success response.If we have errors want to concatenate the field and messages and store the error message as per the abstraction Product Listing general requirements
