   The selected journal **must** be a bank journal for the :guilabel:`Use a payment terminal` field
   to appear.

Finally, fill the mandatory fields with an :guilabel:`Adyen API key`, and an :guilabel:`Adyen

your **Adyen account**.

Then, go to :menuselection:`Developers --> API credentials`. Create a new credential or click on an
existing one.

Click on :guilabel:`Generate an API key` and copy-paste that key onto the Odoo mandatory field.

The **Adyen Terminal Identifier** is your terminal's serial number, which is used to identify the
hardware.

To find this number, go to your **Adyen account**. Then, go to :menuselection:`Point of Sale
--> Terminals`, select the terminal to link, and copy-paste its serial number onto the Odoo
mandatory field.

Add a new payment method

Payment Methods`, and add your new method for Adyen.

Pay with a payment terminal
===========================

When processing a payment, select :guilabel:`Adyen` as the payment method. Check the amount and
click on :guilabel:`Send`. Once the payment is successful, the status changes to :guilabel:`Payment
Successful`.

.. note::
   - | In case of connexion issues between Odoo and the payment terminal, force the payment by
       clicking on :guilabel:`Force Done`, which allows you to validate the order.
     | This option is only available after receiving an error message informing you that the
       connection failed.
   - To cancel the payment request, click on :guilabel:`cancel`.
