# Upload one Base64 object

> Upload a Base64-encoded CDN object with a JSON request.

Upload one Base64-encoded file to FiveMesh CDN from a server-side integration.
Use this route when the source provides Base64 instead of file bytes, such as a
screenshot or mugshot capture.

Requires `cdn:write`.

<Warning>
  Keep the service key in a server-side script. Never send it to a FiveM client,
  NUI bundle or browser.
</Warning>

<ParamField header="Idempotency-Key" type="string">
  Optional key used to replay the same successful upload response after a retry.
</ParamField>

<ParamField body="data" type="string" required>
  Raw standard Base64 or a Base64 data URL such as `data:image/png;base64,...`.
  Padded and unpadded Base64 are accepted.
</ParamField>

<ParamField body="filename" type="string" required>
  Stored filename, including its extension.
</ParamField>

<ParamField body="contentType" type="string">
  File MIME type, such as `image/png`. When omitted, the API uses the MIME type
  from a data URL or falls back to `application/octet-stream`.
</ParamField>

<ParamField body="path" type="string">
  Optional destination folder.
</ParamField>

<ParamField body="metadata" type="object">
  Optional metadata containing string, number or boolean values.
</ParamField>

## FiveM server example

This example sends raw PNG Base64 from a server-side Lua resource. The API key
is read from the server ConVar and never sent to the player.

```lua theme={null}
local apiKey = GetConvar("FIVEMESH_API_KEY", "")

local payload = json.encode({
    data = pngBase64,
    filename = ("family-%d-member-%d.png"):format(familyId, memberId),
    contentType = "image/png",
    path = "family_mugshot",
    metadata = {
        familyId = tostring(familyId),
        memberId = tostring(memberId),
        source = GetCurrentResourceName(),
    },
})

PerformHttpRequest(
    "https://api.fivemesh.io/v1/objects/base64",
    function(statusCode, responseBody, _, errorData)
        local response = responseBody and json.decode(responseBody) or nil

        if statusCode < 200 or statusCode >= 300 or not response then
            print(("[FiveMesh] Upload failed (%s): %s"):format(
                tostring(statusCode),
                responseBody or errorData or "No response"
            ))
            return
        end

        print(("[FiveMesh] Uploaded %s"):format(response.object.publicUrl))
    end,
    "POST",
    payload,
    {
        ["Authorization"] = "Bearer " .. apiKey,
        ["Content-Type"] = "application/json",
    }
)
```

<Info>
  Base64 increases the request size. Prefer the multipart upload route when you
  already have file bytes.
