Create (DAuth) User with Account Access

This endpoint is used as part of the DAuth solution to grant access to account and transaction data to a smart contract on the blockchain.

Put the smart contract address in username

For provider use "dauth"

This endpoint will create the (DAuth) User with username and provider if the User does not already exist.

Authentication is Mandatory and the logged in user needs to be account holder.

For information about DAuth see below:

DAuth

DAuth Introduction, Setup and Usage

DAuth is an experimental authentication mechanism that aims to pin an ethereum or other blockchain Smart Contract to an OBP "User".

In the future, it might be possible to be more specific and pin specific actors (wallets) that are acting within the smart contract, but so far, one smart contract acts on behalf of one User.

Thus, if a smart contract "X" calls the OBP API using the DAuth header, OBP will get or create a user called X and the call will proceed in the context of that User "X".

DAuth is invoked by the REST client (caller) including a specific header (see step 3 below) in any OBP REST call.

When OBP receives the DAuth token, it creates or gets a User with a username based on the smart_contract_address and the provider based on the network_name. The combination of username and provider is unique in OBP.

If you are calling OBP-API via an API3 Airnode, the Airnode will take care of constructing the required header.

When OBP detects a DAuth header / token it first checks if the Consumer is allowed to make such a call. OBP will validate the Consumer ip address and signature etc.

Note: The DAuth flow does not require an explicit POST like Direct Login to create the token.

Permissions may be assigned to an OBP User at any time, via the UserAuthContext, Views, Entitlements to Roles or Consents.

Note: DAuth is NOT enabled on this instance!

Note: The DAuth client is responsible for creating a token which will be trusted by OBP absolutely!

To use DAuth:

1) Configure OBP API to accept DAuth.

Set up properties in your props file

# -- DAuth --------------------------------------
# Define secret used to validate JWT token
# jwt.public_key_rsa=path-to-the-pem-file
# Enable/Disable DAuth communication at all
# In case isn't defined default value is false
# allow_dauth=false
# Define comma separated list of allowed IP addresses
# dauth.host=127.0.0.1
# -------------------------------------- DAuth--

Please keep in mind that property jwt.public_key_rsa is used to validate JWT token to check it is not changed or corrupted during transport.

2) Create / have access to a JWT

Under the hood

The file, dauth.scala handles the DAuth,

We:

-> Check if Props allow_dauth is true
  -> Check if DAuth header exists
    -> Check if getRemoteIpAddress is OK
      -> Look for "token"
        -> parse the JWT token and getOrCreate the user
          -> get the data of the user

Create (DAuth) User with Roles

This endpoint is used as part of the DAuth solution to grant Entitlements for Roles to a smart contract on the blockchain.

Put the smart contract address in username

For provider use "dauth"

This endpoint will create the User with username and provider if the User does not already exist.

Then it will create Entitlements i.e. grant Roles to the User.

Entitlements are used to grant System or Bank level roles to Users. (For Account level privileges, see Views)

i.e. Entitlements are used to create / consume system or bank level resources where as views / account access are used to consume / create customer level resources.

For a System level Role (.e.g CanGetAnyUser), set bank_id to an empty string i.e. "bank_id":""

For a Bank level Role (e.g. CanCreateAccount), set bank_id to a valid value e.g. "bank_id":"my-bank-id"

Note: The Roles actually granted will depend on the Roles that the calling user has.

If you try to grant Entitlements to a user that already exist (duplicate entitilements) you will get an error.
