MngUpdateGateway

Partially updates an existing gateway configuration. The manager restarts a running gateway so the new configuration is applied. Requires SESSION_ADMIN.

HTTP: PUT /gateway

{
  "command":"MngUpdateGateway",
  "id":1,
  "provider_config":{
    "hosts":["fix-1.lp.example:443","fix-2.lp.example:443"],
    "credentials":{"sender_comp_id":"BROKER","password":"new-secret"}
  },
  "heartbeat_timeout_ms":7000
}

The response contains the complete updated gateway object. Only id is required; omitted fields keep their previous values. When supplied, provider_config replaces the complete previous object and causes the gateway instance to restart.

Disabling the gateway stops its runtime. Updating an enabled gateway restarts it asynchronously; check runtime state separately.
