# Sample Clients

## Postman Sample Client <a href="#set-up-postman" id="set-up-postman"></a>

For your convenience, we have created a sample Postman client for you to use which can be accessed on our GitHub here:

### Importing a Collection <a href="#importing-a-collection" id="importing-a-collection"></a>

A base sample client is available to import for Postman. You can follow the documentation to get it up and running.

To import the collection, simply click import in Postman:

Then locate the json file from the cloned repository. File location in repository: **postman\IOBWS 3.0 Payments and accounts.postman\_collection.json.** Select it in Postman:

### Authorization - OAuth 2.0 <a href="#authorization-oauth-2.0" id="authorization-oauth-2.0"></a>

This method shows how the token is received. With this implementation the user needs to get a new access token manually. In the postman collection, the authentication is configured per subfolder, i.e.,  `accounts` , `funds-confirmations` , `consents` , `{payment-service}` .

**If you are calling the sandbox version of the endpoints, simply paste the token into the Token field.**

The following needs to be configured if you intend to call the live version:

**Access Token URL** - <https://curity.arionbanki.is/oauth/v2/oauth-token>

**Client ID** - The clientId you get from creating your application in [Developer Portal](https://developer.arionbanki.is/)

**Client Secret** - The clientSecret you get from creating your application in [Developer Portal](https://developer.arionbanki.is/)

**Scope** - The default scopes you get from creating your application in [Developer Portal](https://developer.arionbanki.is/)

Finally click **Get New Access Token**

You should get an OAuth token from the identity server
