How to create user from existing blockchain addresses?

Our system have an existing user system and we only need to communicate with Moralis from the server side (no browser js integration is necessary).

How to create corresponding Moralis user from our own user’s blockchain address?

Specifically, we need this: https://docs.moralis.io/moralis-server/automatic-transaction-sync/historical-transactions#monitoring-non-authenticated-address. - We want to sync the existing addresses’ balance & transactions.

However, it is not clear how we can achieve it with with our existing user system.

You can use something like this: Moralis.Cloud.run(“watchBscAddress”, { address: Address, “sync_historical”:true })

Or you can insert the data directly in mongo corresponding to what you want to sync and restart server after that. You don’t need to create users.
