Request fields (body)

Field Type Required Description
text string yes Reply text. A whitespace-only string and the string "0" are not accepted

Examples

Terminal 
curl -X POST "https://vibecode.bitrix24.com/v1/notifications/38963/answer" \

  -H "Content-Type: application/json" \

curl -X POST "https://vibecode.bitrix24.com/v1/notifications/38963/answer" \
  -H "X-Api-Key: YOUR_APP_KEY" \
  -H "Authorization: Bearer USER_SESSION_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{ "text": "Got it, thanks" }'

JavaScript — personal key

javascript 
const res = await fetch('https://vibecode.bitrix24.com/v1/notifications/38963/answer', {
  method: 'POST',
  headers: {
    'X-Api-Key': 'YOUR_API_KEY',
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({ text: 'Got it, thanks' }),
})

const { data } = await res.json()
console.log(data.resultMessage[0])

JavaScript — OAuth application

javascript 
const res = await fetch('https://vibecode.bitrix24.com/v1/notifications/38963/answer', {

  body: JSON.stringify({ text: 'Got it, thanks' }),
})

const { data } = await res.json()

Response fields

Field Type Description
success boolean true on success
data.resultMessage string[] Result messages. Bitrix24 writes the text — escape it before rendering it in an interface

Response example

HTTP 200:

JSON 
{
  "success": true,
  "data": {
    "resultMessage": ["Your reply has been sent."]
  }
}

Error response example

422 — the token owner has no notification with this id:

JSON 
{
  "success": false,
  "error": {
    "code": "BITRIX_ERROR",
    "message": "Notification is absent, unavailable to the token owner, or cannot perform this action.",
    "b24Code": "NOTIFICATION_ACTION_FAILED"
  }
}

Errors

HTTP Code Description
400 INVALID_PARAMS The path id is not a positive integer
400 INVALID_PARAMS text is missing, is not a string, is whitespace-only or equals "0"
400 INVALID_PARAMS Another body field or a query string parameter was passed, or the body is not a JSON object. The field is named in the message. Checked before the Bitrix24 call
400 FST_ERR_CTP_EMPTY_JSON_BODY The Content-Type: application/json header was sent with an empty body
422 BITRIX_ERROR The notification does not exist, is unavailable to the token owner or does not accept a reply. The Bitrix24 error code NOTIFICATION_ACTION_FAILED is in the error.b24Code field

Known specifics

  • A reply is also accepted for a notification that has no reply field, for example one sent with POST /v1/notifications. The message in data.resultMessage confirms only that Bitrix24 accepted the reply, not that the source module processed it.
  • A repeated reply to the same notification also returns 200. After a reply the notification stays in the feed and is not marked as read — use Mark as read for that.
  • The reply is sent on behalf of the token owner: with a personal key, the key owner; with an OAuth application key and the Authorization: Bearer header, the session user.
