Vizio SmartCast API (2016+ Models)

API Clients

The following API clients are available based on these API docs:

vizio-smart-cast (JavaScript)
pyvizio (Python)

Overview

On firmware versions older than 4.0 the API server runs on port 9000, on 4.0 and newer the API server runs on port 7345. Both are using https and will not respond to http.

Don't port forward it. There are some commands that can be executed without authentication.
Certificate's CN is BG2.prod.vizio.com so will likely fail SSL validation.
API includes a Status object, URI requested, and Execution time on every response. It's included below, but excluded in all of the examples for redundancy.
```
 {
 	...
 	"STATUS": {
 		"RESULT": String,
 		"DETAIL": String
 	},
 	"URI": String,
 	"TIME": String
 }
```
API does not seem to be fully restful, and doesn't apply proper status codes in responses. Verify request's result from the status object. Result codes included where applicable.
All requests made should contain a JSON body with the header Content-Type: application/json set.
When authentication is required, send Auth: AUTH_TOKEN header with request.
This does not cover any MyVizio Account APIs.

Display Discovery

Find IP Address

Perform an SSDP query for ST: urn:schemas-kinoma-com:device:shell:1

Example

M-SEARCH * HTTP/1.1
HOST: 239.255.255.250:1900
MAN: "ssdp:discover"
MX: 1
ST: urn:schemas-kinoma-com:device:shell:1

Pairing

required to control set.

Start Pairing

PUT /pairing/start

Body

{
	"DEVICE_NAME": String,
	"DEVICE_ID": String
}

Response

{
	"ITEM": {
		"PAIRING_REQ_TOKEN": Integer,
		"CHALLENGE_TYPE": Integer
	},
	...
}

cURL Example

curl -k -H "Content-Type: application/json" -X PUT -d '{"DEVICE_ID":"12345","DEVICE_NAME":"cURL Example"}' https://myVizioTV:9000/pairing/start

Notes

Save DEVICE_ID, you'll need it for the challenge or to cancel pairing.

Submit Challenge

PUT /pairing/pair

Body

{
  "DEVICE_ID": String,
  "CHALLENGE_TYPE": Integer,
  "RESPONSE_VALUE": String,
  "PAIRING_REQ_TOKEN": Integer
}

Response

{
	"ITEM": {
		"AUTH_TOKEN": String
	},
	...
}

cURL Example

curl -k -H "Content-Type: application/json" -X PUT -d '{"DEVICE_ID": "12345","CHALLENGE_TYPE": 1,"RESPONSE_VALUE": "1234","PAIRING_REQ_TOKEN": 654321}' https://myVizioTV:9000/pairing/pair

Notes

RESPONSE_VALUE key is the code displayed on the TV.
PAIRING_REQ_TOKEN key is returned from the /pairing/start request.

Cancel Pairing

PUT /pairing/cancel

Body

{
  "DEVICE_ID": String,
  "CHALLENGE_TYPE": Integer,
  "RESPONSE_VALUE": "1111",
  "PAIRING_REQ_TOKEN": Integer
}

Response

{
	"ITEM": {},
	...
}

cURL Example

curl -k -H "Content-Type: application/json" -X PUT -d '{"DEVICE_ID":"12345","CHALLENGE_TYPE": 1,"RESPONSE_VALUE": "1111","PAIRING_REQ_TOKEN": 0}' https://myVizioTV:9000/pairing/cancel

Notes

For cancellation, RESPONSE_VALUE should be hard-coded to "1111".

Appendix

Status Results

RESULT	Meaning
INVALID_PARAMETER	Malformed Request
MAX_CHALLENGES_EXCEEDED	Too many failed pair attempts
SUCCESS	Successfully Paired
PAIRING_DENIED	Incorrect Pin
VALUE_OUT_OF_RANGE	Pin out of range
CHALLENGE_INCORRECT	Incorrect challenge
BLOCKED	Pairing in progress already

Remote Control Methods

Turning Set on From Sleep

The HTTP API server turns off when the set is sleeping. Send a WoL magic packet to turn it on. not supported when set runs in Eco mode.

Power State

Authenticated

GET /state/device/power_mode

Response

{
	"ITEMS": [{
		"TYPE": "T_VALUE_V1",
		"CNAME": "power_mode",
		"NAME": "Power Mode",
		"VALUE": 1
	}],
	"PARAMETERS": {
		"HASHONLY": "FALSE",
		"FLAT": "TRUE",
		"HELPTEXT": "FALSE"
	}
	...
}

cURL Example

curl -k -H "Content-Type: application/json" -H "AUTH: 123A456B" -X GET https://myVizioTV:9000/state/device/power_mode

Send remote control button press

Authenticated

PUT /key_command/

Body

{
	"KEYLIST": [{
		"CODESET": Integer,
		"CODE": Integer,
		"ACTION": String
	}]
}

cURL Example

curl -k -H "Content-Type: application/json" -H "AUTH: 123A456B" -X PUT -d '{"KEYLIST": [{"CODESET": 5,"CODE": 0,"ACTION":"KEYPRESS"}]}' https://myVizioTV:9000/key_command/

Notes

You can string together long remote actions by adding to the keylist array.
