Middleware for Data Mapping Parameters & Events

We need someone that have experience with mapping data into a middleware.
Data will be sent from a source in JSON HTTP and we will map this data in the middleware because the parameters from the source are not the same as what our portal can recognize.

We have already a log of the data from the source and we have also prepared the files from our portal so you can see how this data will be accepted/recognized by our portal.

After the middleware is created we need too point URL as endpoint where too sent the data in our portal.
