How to create users through rest api using springboot

i want to create user through posting data in database using my rest api using springboot but i am not understanding how i post password and i pass data in database table users it is showing there but not in user when i open my suite crm

Make sure you have deleted flag =0 and you can put a md5 encrypted password in the user_hash field

where i have to do that deleted flag=0 and do i need to integrate my api to suitecrm api or just posting data inside the database of suitecrm table will work

Just posting data into the users table should work. you can also do this using the suitecrm api. In the users table there is a column deleted it’s value should be 0.
I will advise looking at a row(in database) which is already showing in the users module and try to copy the values from that row

can i add md5 hashing in my code to genrate user_hash when i give a password it sholud change into user_hash

you can add md5 hashing in your code to generate user_hash
