The following section describes the technical steps to get started with the integration. It is an additional resource which that completes our openAPI description of the REST API.

Web form Form 2.0 services use Access () in order to implement various workflows. The below steps is a pre-requisite are the prerequisites to use Web form’s Form 2.0' REST services. Essentially, it creates a secure profile for the customer and individual secure profiles for their end users necessary for consuming web form services

finAPI follows the OAuth 2.0 Standard for authorizing applications and users within them. OAuth uses the terminology of clients and users. A client represents an application that calls finAPI services. A service call might be in the context of a user of the client (e.g: getting a user's bank connections), or outside any user context (e.g.: editing your client's configuration, or creating a new user for your client). In any case, every service call must be authorized by an access_token. The documentation below describes how to set up client's users, or for the client itself.

Step 1: Get authorized as a client in Access

The major prerequisite for getting authorized as a client (i.e. application) is having a valid set of client credentials: client_id and client_secret.

To get authorized as a client, make a call to Access POST /oauth/ tokentokenand pass the following request parameters:

• grant_type=client_credentials

• client_id

• client_secret

The client authorization request response:

{
  "access_token": "fnsXpguIBkChhCsN8bVty9Y68AsUvJYyXUILcsFBvWABF03k8Ov68Ev2BTyANuBjyX8r9XuuTajNM2zZnhZMDjKWHN4lbRSRcVhg9_PcE7eeXHm0t28ZjzM4TJlrupZD",
  "token_type": "bearer",
  "expires_in": 3599,
  "scope": "all"
}

To get authorized as a Client, use the obtained access_token as an input for Access QUICK AUTH.

Step 2: Create an Access user

The major prerequisite for creating a user is getting authorized as a client with the help of the obtained access_token in Step 1.

To create a user, make a call to Access POST /users and pass the following request body:

{
  "id": "username",
  "password": "password",
  "email": "email@localhost.de",
  "phone": "+49 99 999999-999",
  "isAutoUpdateEnabled": false
}

The user creation request response:

{
  "id": "username",
  "password": "password",
  "email": "email@localhost.de",
  "phone": "+49 99 999999-999",
  "isAutoUpdateEnabled": false
}

Step 3: Get authorized as a user

The major prerequisite for creating a user is getting the user’s data, such as password and id (username) from the Step 2.

To get authorized as a user, make a call to Access POST /oauth/tokenand pass the following request parameters:

• grant_type=password

• client_id

• username

• password

The user authorization request response:

{
  "access_token": "nnsXpguIBkChhCsN8bVty9Y68AsUvJYyXUILcsFBvWABF03k8Ov68Ev2BTyANuBjyX8r9XuuTajNM2zZnhZMDjKWHN4lbRSRcVhg9_PcE7eeXHm0t28ZjzM4TJlrupZD",
  "token_type": "bearer",
  "expires_in": 3599,
  "scope": "all"
}

To get authorized as a User, use the obtained access_token as an input for DI QUICK AUTH (should be updated) Web Form QUICK AUTH

Once the above steps are completed, any of the workflows related to AIS(Account Information Services) or PIS (Payment Initiation Services) can be triggered successfully either standalone (on a browser) or as an embedded Web Form.
