Magento 2 - Callback url not receiving response from doofAPI

[Aitor-Corrales]

Whenever a client creates the structure in Doofinder as a result of the installation of the plugin in a Magento 2 platform, as a result, its products should be indexed and when this process finishes, the callback url in the client's platform should be notified.

This process is not working and as a consequence, the indexation status view is not working. Moreover, the layer is not being activated automatically either.
