Your Merchant Token is needed for your VAT registration for Germany.

Your merchant token is a unique seller identifier used in AMTU, third-party applications and XML feeds to match up products that you upload with your seller account.

Note: You cannot share a merchant token with other sellers or use it for different seller accounts. It is unique to a given seller.

Is this necessary for getting VAT registration in Germany?

This information is 100% needed if you want to get German VAT registration for a foreign company (I mean, not a company based in Europe), so I always recommend my clients to provide for the registration in order to avoid unnecessary delays.
