How to build input connector in case of a few json objects (vehicles)

[IliaIvanov]

Dear GeoNet Community, good day

If someone was facing similar case, will be grateful for your help.

I have the following JSON structure:

Each of those objects (vehicles) has the following structure:

I'd like to create a GeoEvent service, containing all of those objects and do this with one Input Connector if it's possible.

At first, I am wondering whether I can create a geometry  from fields for all those objects without using Field Calculator processor, because, in that case, I have to do that for each object separately. But what if have I have 400 those objects?

Please, share your knowledge.

Kind regards,

Sibdar
