+Configuration on the Xendit Dashboard
+=====================================
+
+#. Create a Xendit account if necessary and log in to the `Xendit Dashboard
+   <https://dashboard.xendit.co>`_.
+#. Check your account mode in the top left corner of the page. Use the :guilabel:`Test Mode` to try
+   the integration without charging your customers. Switch to :guilabel:`Live Mode` once you are
+   ready to accept payments.
+#. Navigate to :menuselection:`Configuration: Settings` in the left part of the application page.
+   In the :guilabel:`Developers` section, click
+   `API Keys <https://dashboard.xendit.co/settings/developers#api-keys>`_.
+#. Click :guilabel:`Generate Secret Key`. In the popup box, enter any :guilabel:`API key name`,
+   select :guilabel:`Write` for the :guilabel:`Money-in Products` permission and :guilabel:`None`
+   for all other permissions then click :guilabel:`Generate key`.
+#. Confirm your password to display your API key. Copy or download the key and **save
+   this information securely for later**. This is the only time the API key can be viewed or
+   downloaded.
+#. Once completed, scroll down the page to the
+   `Webhooks <https://dashboard.xendit.co/settings/developers#webhooks>`_ section to generate
+   the webhook token.
+#. Under :guilabel:`Webhook verification token`, click :guilabel:`View Webhook Verification Token`,
+   then confirm your password to display the token. Save it for later.
+#. In the :guilabel:`Webhook URL` section, enter your Odoo database URL (e.g.,
+   `https://example.odoo.com`) in the field :guilabel:`Invoices paid` and click the
+   :guilabel:`Test and save` button next to it.
+
+Configuration on Odoo
