[SR-Users] Kamailio integration with REST services

Hi all! I need to integrate a REST Service with Kamailio. Integration is easy, not a problem, but my concern is that the REST Services has a JWT token authentication required for each request, common to many (it not all) REST Services. So, it is required to POST for authentication (username and password) and once I get authentication done, and receive a JWT token, I will need to use this token in all other requests to the REST Service. The token is valid for 24h. My question is: - how to save the token for use during 24h, on all calls/sessions, without the need to authenticate on every call? - how to detect the token has expired and re-authenticate? I looked for some modules, but could not find any that suited me. I am thinking of executing a Python script for this, but concerned about latency and PDD.... Any thoughts? Any suggestions? Any known best-practice? Atenciosamente / Kind Regards / Cordialement / Un saludo, *Sérgio Charrua*
