Scrapping web -- 2

I need to scrape the json.

First run:
https://sedeapl.dgt.gob.es/WEB_EXAM_AUTO/service/VerificarExamenServlet?tipoCuest=A1&idioma=1

Then run:
https://sedeapl.dgt.gob.es/WEB_EXAM_AUTO/service/RecuperarAspiranteServlet

The json result must be saved in a file. The script must be programmed in PHP.
