webapi returns variables in JSON using snake case and I need camelCase

[csdougliss]

Precondition (*)

Magento 2.3.x

Summary (*)

I want to return JSON in camelCase in my custom webapi.xml and interface that I have created.
There is no way to configure in webapi.xml the format that you wish to use.

By default M2 will return data like so: server_transaction_id but my third party JavaScript is expecting serverTransactionId for example.

Secondly, It is also rather annoying to have to create an interface to do this instead of just being able to use json_encode the data. Using json_encode is not the solution as you end up with \ in the format.

See below:

Examples (*)

interface Check3dsVersionInterface
{
    /**
     * @return string
     */
    public function getServerTransactionId();

    /**
     * @param string $serverTransactionId
     * @return $this
     */
    public function setServerTransactionId($serverTransactionId);

webapi.xml:

<route url="/V1/xx-payments/:cartId/check-3ds-version" method="POST">
        <service class="xx\xx\Api\xxServiceInterface" method="check3dsVersion"/>
        <resources>
            <resource ref="anonymous" />
        </resources>
    </route>

Proposed solution

In webapi.xml, it would be useful to specify the format of the json, for example to return as camelCase or as it is currently which is underscores
