Use FiveMesh CDN with LB-Phone or LB-Tablet by configuring a custom upload method. Use presigned uploads so the script can upload phone or tablet media without exposing your FiveMesh service key to clients.
If you use both LB-Phone and LB-Tablet, give each script its own CDN path prefix such as /phone and /tablet. You can restrict service keys to those prefixes from the FiveMesh dashboard.

​
Prerequisites

Before you begin, confirm:
  • FiveMesh CDN is set up for the active workspace.
  • You have a service key with CDN write access.
  • The service key is scoped to the path prefixes the script should manage.
  • You can edit the LB-Phone or LB-Tablet server files.
Use these values while configuring the integration:
ValueDescription
FIVEMESH_PRESIGNED_UPLOAD_URLThe presigned upload endpoint provided for your FiveMesh workspace or integration environment.
YOUR_API_KEYA scoped FiveMesh service key.
YOUR_CDN_WORKSPACEThe CDN workspace name you configured during setup.
fileThe upload field name used by LB-Scripts.
Do not configure direct uploads with a permanent API key in client-visible files. Keep the service key in server-side LB-Scripts files and return presigned upload URLs to the client.

​
LB-Phone configuration

To use presigned uploads with LB-Phone, update the server and upload configuration.
1

Configure server credentials

Open lb-phone/server/apiKeys.lua and configure the API keys, workspace names and target path prefixes.
API_KEYS = {
    Video = "YOUR_API_KEY",
    Image = "YOUR_API_KEY",
    Audio = "YOUR_API_KEY",
}

CDN_WORKSPACES = {
    Video = "YOUR_CDN_WORKSPACE",
    Image = "YOUR_CDN_WORKSPACE",
    Audio = "YOUR_CDN_WORKSPACE",
}

CDN_PATH_PREFIXES = {
    Video = "/phone/video",
    Image = "/phone/images",
    Audio = "/phone/audio",
}

FIVEMESH_PRESIGNED_UPLOAD_URL = "YOUR_PRESIGNED_UPLOAD_ENDPOINT"
2

Request a presigned upload URL

Update lb-phone/server/custom/functions/functions.lua to implement GetPresignedUrl.
function GetPresignedUrl(source, uploadType)
    local apiKey = API_KEYS[uploadType]
    local workspace = CDN_WORKSPACES[uploadType]
    local pathPrefix = CDN_PATH_PREFIXES[uploadType]

    if not apiKey or not workspace or not pathPrefix then
        infoprint("error", ("[GetPresignedUrl] Invalid uploadType '%s'"):format(uploadType))
        return false
    end

    local p = promise.new()

    local endpoint = ("%s?randomizeName=true&workspace=%s&pathPrefix=%s"):format(
        FIVEMESH_PRESIGNED_UPLOAD_URL,
        workspace,
        pathPrefix
    )

    PerformHttpRequest(
        endpoint,
        function(status, body, headers, error)
            if status ~= 200 then
                infoprint("error", ("[GetPresignedUrl] Request failed for '%s', status: %s"):format(uploadType, status))
                p:resolve(false)
                return
            end

            local ok, data = pcall(json.decode, body)
            if not ok or not data or not data.url then
                infoprint("error", ("[GetPresignedUrl] Invalid response for '%s'"):format(uploadType))
                p:resolve(false)
                return
            end

            p:resolve(data.url)
        end,
        "GET",
        nil,
        { ["Authorization"] = ("Bearer %s"):format(apiKey) }
    )

    return Citizen.Await(p)
end
3

Use presigned URLs in upload settings

In lb-phone/shared/upload.lua, set url to "PRESIGNED_URL" for custom methods.
UploadMethods = {
    Custom = {
        Video = {
            url = "PRESIGNED_URL",
            field = "file",
        },
        Image = {
            url = "PRESIGNED_URL",
            field = "file",
        },
        Audio = {
            url = "PRESIGNED_URL",
            field = "file",
        },
    }
}
4

Return the custom method

Confirm CustomGetUploadMethod exists in lb-phone/client/custom/functions/functions.lua.
---@param uploadType "Video" | "Image" | "Audio"
---@return UploadMethod?
function CustomGetUploadMethod(uploadType)
    local methods = UploadMethods[Config.UploadMethod[uploadType]]
    if not methods then
        infoprint("error", "Upload methods not found for ", uploadType)
        return
    end

    ---@type UploadMethod?
    local method = methods[uploadType] or methods.Default
    if not method then
        infoprint("error", "Upload method not found for ", uploadType)
        return
    end

    return method
end

​
LB-Tablet configuration

LB-Tablet uses the same presigned upload pattern.
1

Configure server credentials

Open lb-tablet/server/apiKeys.lua and add the same API_KEYS, CDN_WORKSPACES, CDN_PATH_PREFIXES and FIVEMESH_PRESIGNED_UPLOAD_URL values.
2

Request a presigned upload URL

Update lb-tablet/server/custom/functions/functions.lua with the same GetPresignedUrl function used for LB-Phone.
3

Use presigned URLs in upload settings

In lb-tablet/config/upload.lua, set url = "PRESIGNED_URL" for each custom media type.
4

Return the custom method

Confirm CustomGetUploadMethod is implemented in lb-tablet/client/custom/functions/functions.lua.
