# Testing (/data-api/guides/core-concepts/testing)

Test your Fiskil integration with the Sandbox environment



With the Fiskil Sandbox, you can develop and integration test your application in an environment that mirrors production. The sandbox supports unlimited End-Users and consents with realistic data across both Banking and Energy domains.

In the steps below we'll create a new consent using Fiskil Console and then fetch sample data via the API.

Prerequisites [#prerequisites]

Ensure you have access to [Fiskil Console](https://console.fiskil.com). To set up the sandbox for your team or manage permissions, contact [customer support](https://fiskil.atlassian.net/servicedesk/customer/portal/6).

Getting Started [#getting-started]

Step 1: Generate API Key [#step-1-generate-api-key]

If you haven't already, navigate to [API Keys](https://console.fiskil.com/settings/api-keys) in the console to create a key pair. Note your `client_id` and `client_secret` for authentication.

Step 2: Get an access token [#step-2-get-an-access-token]

Exchange your credentials for an `access token` using the `/v1/token` endpoint.

```bash
curl --location --request POST 'https://api.fiskil.com/v1/token' \
--header 'Content-Type: application/json' \
--header 'Accept: application/json' \
--data-raw '{
  "client_id": "${client_id}",
  "client_secret": "${client_secret}"
}'
```

Step 3: Create an End-User [#step-3-create-an-end-user]

Create a new End-User to test the APIs. For simplicity, create a single consent per End-User. You'll need a `name`, `email` and `phone`. Use the `access token` from the previous step.

```bash
curl --location --request POST 'https://api.fiskil.com/v1/end-users' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer ${access_token}' \
--data-raw '{
  "name": "Test User",
  "email": "test@example.com",
  "phone": "+1234567890"
}'
```

Step 4: Create Auth Session [#step-4-create-auth-session]

From [End-Users](https://console.fiskil.com/end-users) in the console, select your user and click **Create Auth Session**. Open the generated link in a new browser window.

Grant access by selecting **Allow**. You'll then see the provider selection screen.

Step 5: Choose the Sandbox Provider [#step-5-choose-the-sandbox-provider]

Select the relevant sandbox provider (Bank or Energy Retailer).

Step 6: Complete OTP Authentication [#step-6-complete-otp-authentication]

Enter any email you can access and click **get code** to receive a one-time password.

Step 7: Account Selection [#step-7-account-selection]

Choose one of the available accounts for your consent. After selecting the account, confirm the consent by clicking **Confirm and share**. You have successfully created a consent in the sandbox environment.

For example account details, see the sub‑pages below for Banking and Energy sample accounts.
