How to use REST API to accept new folders

Support

After a bit of fiddling with the jq tool:

jq --arg l "My Label" --arg p /path/to/folder \
   '{ id: . | keys[], label: $l, path: $p, devices: .[].offeredBy | keys | map({ deviceID: . }) }'\
<<EOF
{
  "kmmgl-nygfm": {
    "offeredBy": {
      "Z2M6GO2-455NXSO-CQLJVBB-IIG5MPA-ERT636W-LUK3GUC-MUSIBP6-6UIVQQF": {
        "time": "2021-10-20T18:18:40Z",
        "label": "syncthing-restAPI",
        "receiveEncrypted": false,
        "remoteEncrypted": false
      }
    }
  }
}
EOF
{
  "id": "kmmgl-nygfm",
  "label": "My Label",
  "path": "/path/to/folder",
  "devices": [
    {
      "deviceID": "Z2M6GO2-455NXSO-CQLJVBB-IIG5MPA-ERT636W-LUK3GUC-MUSIBP6-6UIVQQF"
    }
  ]
}

(Note the <<EOF so-called heredoc syntax is just for this example usage. Redirect from a file or build a pipe as you see fit in your use case.)

Obviously doesn’t handle all the details, but it’s a start for most stuff that can be processed automatically. remoteEncrypted cries for a password to be supplied if true. The label can be different when offered from several devices, so it’s ambiguous which one to pick.
