+### Registering Payment
+
+This method registers a new payment for the given installation and account, returning a `hash`,
+containing the risk assessment and supporting evidence.
+
+```ruby
+assessment = api.register_payment(
+  installation_id: 'installation-id',
+  account_id: 'account-id'
+)
+
+# => #<OpenStruct id="...", device_id="...", risk_assessment="..", evidence=...>
+```
+
+It also supports optional parameters, for example:
+
+```ruby
+addresses = [
+  {
+    'type': 'shipping',
+    'structured_address': {
+      'locale': 'pt-BR',
