Please take a look at the OpenAPI schema for the exact definitions of user, folder and admin fields.
If you need an example you can export a dump using the Web Admin or by invoking the dumpdata endpoint directly, you need to obtain an access token first, for example:
$ curl "http://admin:[email protected]:8080/api/v2/token"
{"access_token":"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJhdWQiOlsiQVBJIl0sImV4cCI6MTYxMzMzNTI2MSwianRpIjoiYzBrb2gxZmNkcnBjaHNzMGZwZmciLCJuYmYiOjE2MTMzMzQ2MzEsInBlcm1pc3Npb25zIjpbIioiXSwic3ViIjoiYUJ0SHUwMHNBUmxzZ29yeEtLQ1pZZWVqSTRKVTlXbThHSGNiVWtWVmc1TT0iLCJ1c2VybmFtZSI6ImFkbWluIn0.WiyqvUF-92zCr--y4Q_sxn-tPnISFzGZd_exsG-K7ME","expires_at":"2021-02-14T20:41:01Z"}

These properties are stored inside the configured data provider.
SFTPGo supports checking passwords stored with bcrypt, pbkdf2, md5crypt and sha512crypt too. For pbkdf2 the supported format is $<algo>$<iterations>$<salt>$<hashed pwd base64 encoded>, where algo is pbkdf2-sha1 or pbkdf2-sha256 or pbkdf2-sha512 or $pbkdf2-b64salt-sha256$. For example the pbkdf2-sha256 of the word password using 150000 iterations and E86a9YMX3zC7 as salt must be stored as $pbkdf2-sha256$150000$E86a9YMX3zC7$R5J62hsSq+pYw00hLLPKBbcGXmq7fj5+/M0IFoYtZbo=. In pbkdf2 variant with b64salt the salt is base64 encoded. For bcrypt the format must be the one supported by golang's crypto/bcrypt package, for example the password secret with cost 14 must be stored as $2a$14$ajq8Q7fbtFRQvXpdCq7Jcuy.Rx1h/L4J60Otx.gyNLbAYctGMJ9tK. For md5crypt and sha512crypt we support the format used in /etc/shadow with the $1$ and $6$ prefix, this is useful if you are migrating from Unix system user accounts. We support Apache md5crypt ($apr1$ prefix) too. Using the REST API you can send a password hashed as bcrypt, pbkdf2, md5crypt or sha512crypt and it will be stored as is.
If you want to use your existing accounts, you have these options:
- you can import your users inside SFTPGo. Take a look at convert users script, it can convert and import users from Linux system users and Pure-FTPd/ProFTPD virtual users
- you can use an external authentication program
