Hi,
i know that post-call voice survey is not supported by Genesys, but I've found and use this:
Https://github.com/mcphee11/genesys-cloud-voice-survey

it works well for NPS, but when i add 2nd question, i can't find proper input place.
it using answerID:
"answerOptions": [{
"id": "01b28df9-00cb-4ffa-9631-5cb9d5617920",
"text": "1",
"value": 1
}, {
"id": "c31a11e5-391c-4720-a249-92da59f937b0",
"text": "2",
"value": 2
}, {
"id": "aa2a8cc9-86d6-4e4b-976f-5768e2f238a2",
"text": "3",
"value": 3
}, {
"id": "abf50314-5787-4a3a-91a8-cb0196608be2",
"text": "4",
"value": 4
}, {
"id": "f911aa12-b2a3-497c-86da-1da3e3739ebc",
"text": "5",
"value": 5
}]

and in NPS question it's simple:
"npsScore": 10 =>. "npsScore": $ {input.question2}

Do you have any ideas how to solve it?

Found a way how to solve it:

• add Switch into Flow (where i update data table)
• convert answer from DTMF to answerID (as in json)
• and then just Post in survey in proper format.
