 # Wallet API Specification
+
+## Points of extensions
+
+### Generic destination resources
+
+This allows adding new destination resources which should be handled by _wapi_ in a generic manner.
+
+Provided through vendor extension `x-vality-genericMethod`, which should be a JSON object. You can set it on a model discriminated against `DestinationResource`. When it's set on an object its `type` value will be used to identify this resource's [payment service](https://github.com/valitydev/fistful-proto/blob/eeff5ba9/proto/base.thrift#L167).
+
+At the moment this object may contain following properties:
+
+1. `schema` object, which should be a valid JSON schema.
+
+    A `DestinationResource` object following this schema will be interpreted as _generic resource data_ and passed down as part of [`ResourceGeneric.generic.data`](https://github.com/valitydev/fistful-proto/blob/eeff5ba9/proto/base.thrift#L179) thrift model (which will eventually become [`GenericPaymentTool.data`](https://github.com/valitydev/damsel/blob/b25d3365/proto/domain.thrift#L1855)).
+
+    When `id` schema property is defined, its value will be used to annotate _generic resource data_ data, namely through [MIME type](https://github.com/valitydev/fistful-proto/blob/eeff5ba9/proto/base.thrift#L174).
