To save changed variables in Vapi’s Update Assistant API: 1. Send a PATCH request to

/assistant/{id}

with the updated

variables

in the JSON body, e.g.:

json
   {
     "variables": {
       "key1": "new_value1",
       "key2": "new_value2"
     }
   }

2. Include your auth token in the headers (

Authorization: Bearer <token>

). 3. A successful response (200 OK) confirms the variables are updated; no separate "save" is needed.
