+All components can be passed an optional, unique, `id` field holding a 32-bit integer identifier to later identify them in interaction responses. Do not confuse this with the `custom_id` field for interactive components! You can find more information about this [on the discord api documentation](https://discord.com/developers/docs/components/reference#anatomy-of-a-component). Discord will automatically populate the `id` of components that don't have the `id` specified in the payload sequentially starting from `1`. The `id` value `0` is treated as empty. The order components are automatically filled in is an implementation detail and not officially document. If you want to work with the `id` (for example to find and replace the content of a specific component lateron), you should explicitly specify it.
