You would add it as another parameter in that update request: https://stripe.com/docs/api/metadata

So something like:

                    proration_behavior: 'always_invoice',
                    items: [
                        {
                            id: payload.subscriptionItemId,
                            plan: payload.newPlan.yearly_price_id,
                        },
                    ],
                    proration_date: payload.prorationDate,
                      metadata: {
                        'order_id': '6735',
                      },
                });```

I've tried this, however, when I check the charge.succeeded event, the metadata does not show.

Metadata isn't automatically copied between objects

Metadata on the Subscription will get copied to the Invoice Items that are associated with the subscription but it won't get copied to the payments

You can copy the metadata down to the charge when you get that event, but you will need to retrieve it from the subscription itself first
