Connect Deuna to enable the provider in your workspace and make the payment node available in Brain Studio with external confirmation from the Deuna app.

​
Before you begin

Make sure you have:
  • An active Deuna business account with onboarding completed
  • Merchant code, Api Key, and Api Secret for the environment you will connect (test or production)
  • The applied VAT you will use for the operation
To obtain or review credentials, follow Obtaining credentials.
Merchant code, Api Key, and Api Secret are only available after completing Enterprise onboarding with Deuna.Deuna uses different credentials for test and production. During installation, choose the credential type and paste the keys for that environment.

​
Ways to start installation

You can start Deuna installation from different points in Brain Studio. All routes use the same provider configuration.
Ask Jelou Agent to add payments with Deuna while you build or adjust a flow.Examples:
  • “Add Deuna payments to this flow”
  • “I need to charge with Deuna in this case”
Jelou Agent detects Deuna as an available provider from Marketplace and triggers the assisted installation flow.
All installation routes use the same provider configuration. What changes is where you start the flow.

​
Common installation flow

Regardless of the entry point, the shared process is as follows.

Use Deuna from the Payments node in Canvas

After installing, you can use Deuna from the Payments node in Canvas, regardless of whether you started installation from Jelou Agent, Marketplace, the Payments node, or a template.

​
Test vs production credentials

Test credentials do not process real payments. Before operating in production, you must move the integration using production credentials.
If you connected Deuna with test credentials, set the node to Development and test the Payment method you use in your flow. See Usage and configuration.

​
Go to production

If you installed Deuna with test credentials, you can go to production when ready. You must enter Deuna production credentials.
1

Open Go to production

You can start the change from:
  • The Deuna node’s advanced sidebar in Canvas
  • The Deuna page in Marketplace
In both cases, the same modal opens to move the integration to production.
2

Enter production credentials

Enter the production Api key, Api secret, and merchant code provided by Deuna.
Deuna Go to production modal with production Api key, Api secret, and merchant code

Go to production: Deuna production credentials

In production, each transaction has a cost of $0.10 USD per payment, deducted from your Brain Studio balance, in addition to provider fees.

Confirm the change

Confirm the action. From that moment on, the integration operates with production credentials.

​
Change credentials

  • To move from test to production with the same installation, use Go to production.
  • To rotate credentials or replace the configuration, disconnect Deuna and reinstall following the common installation flow on this page.
