POST

/v1/user/balances/crypto-and-fiat

This endpoint creates a new user.

Each user must be uniquely identified using the externalUserId field. Attempts to reuse an existing ID will result in an error.

Once created, submit user documents using either Add KYC File or the KYC by P100 flow, and then finalize the process with the Add User Verification endpoint.

If the user is from a country that requires proof of address (POA), the response will include the field:

"poaRequiredForExtended": true
