whe have 3 API on each apps (mock and api)

1. api

   1. validate

      handle on user module, this api will call the validate on mock service, and mock service will check whether the account exist and name is simmilar with the request

   2. disbursment

      handle on transaction module, is to create transfer request (disbursement) and the the transaction will put on hold until the bank setled or canceled the transaction via callback

   3. disbursement callback

      handle on transaction module, to receive status from bank service (mock) and store the status into db

2. bank (mock)

   1. validate

      handle on user module, the api will receive name and account number, will check account number on db and validate with name

   2. transfer

      handle on transaction module, the api will receive transaction object and give HOLD status to the transaction

   3. settlement

      handle on transaction module, the api will receive transaction object with the updated status and call api service callback to update the status of the transaction

every step need to open different terminal, step to run:

1. run db

   docker-compose up --build -d

after run, we can test it via postman, the collection already in the repo
