How to import Messages using Ringotel API

Here is an example call sequence to import messages:

For each chat/dialog, you need to obtain a sessionid parameter first. For this, send a message without content to the user’s extension and get a sessionid in response. For example:

POST https://shell.ringotel.co/api

{
"method": "message",
"params":{
  "orgid": "16287540703457500320",
  "from": "1234567890,
  "to": "502"
}

Response:

“result”: {
  "sessionid": "1710004869211-d3103a34bd2ce6023a"
}

Create messages by sending the message API method with the "sessionid", "content" and "timestamp" parameters.
Repeat 1 and 2 for each party number.
Repeat 1, 2 and 3 for each user.

Messages with provided "sessionid" value are marked as read after importing.

timestamp field takes a number value in milliseconds since 01.01.1970
