+title: API Package Interfaces
+
+Ponzu provides a set of interfaces from the `system/api` package which enable 
+richer interaction with your system from external clients. If you need to allow 
+3rd-party apps to manage content, use the following interfaces.
+
+The API interfaces adhere to a common function signature, expecting an 
+`http.ResponseWriter` and `*http.Request` as arguments and returning an `error`.
+This provides Ponzu developers with full control over the request/response 
+life-cycle.
+
+---
+
+## Interfaces
+
+### [api.Createable](https://godoc.org/github.com/ponzu-cms/ponzu/system/api#Createable)
+Externalable enables 3rd-party clients (outside the CMS) to send content via a 
+`multipart/form-data` encoded `POST` request to a specific endpoint: 
+`/api/content/create?type=<Type>`. When `api.Createable` is implemented, content 
+will be saved from the request in a "Pending" section which will is visible only 
+within the CMS.
+
+To work with "Pending" data, implement the [`editor.Mergeable`](/Interfaces/Editor#editormergeable)
+interface, which will add "Approve" and "Reject" buttons to your Content types'
+editor -- or implement [`api.Trustable`](#apitrustable) to bypass 
+the "Pending" section altogether and become "Public" immediately. 
+
+##### Method Set
+
+```go 
+type Createable interface {
+    Create(http.ResponseWriter, *http.Request) error
+}
+```
+
+##### Implementation
+```go
+func (p *Post) Create(res http.ResponseWriter, req *http.Request) error {
+    return nil
+}
+```
+
+---
+
+### [api.Updateable](https://godoc.org/github.com/ponzu-cms/ponzu/system/api#Updateable)
+Updateable enables 3rd-party clients (outside the CMS) to update existing content 
+via a `multipart/form-data` encoded `POST` request to a specific endpoint: 
+`/api/content/update?type=<Type>&id=<id>`. Request validation should be employed 
+otherwise any client could change data in your database.
+
+##### Method Set
+
+```go 
+type Updateable interface {
+    Update(http.ResponseWriter, *http.Request) error
+}
+```
+
+##### Implementation
+```go
+func (p *Post) Update(res http.ResponseWriter, req *http.Request) error {
+    return nil
+}
+```
+
+---
+
+### [api.Deleteable](https://godoc.org/github.com/ponzu-cms/ponzu/system/api#Deleteable)
+Updateable enables 3rd-party clients (outside the CMS) to delete existing content 
+via a `multipart/form-data` encoded `POST` request to a specific endpoint: 
+`/api/content/delete?type=<Type>&id=<id>`. Request validation should be employed 
+otherwise any client could delete data from your database.
+
+##### Method Set
+
+```go 
+type Deleteable interface {
+    Delete(http.ResponseWriter, *http.Request) error
+}
+```
+
+##### Implementation
+```go
+func (p *Post) Delete(res http.ResponseWriter, req *http.Request) error {
+    return nil
+}
+```
+
+---
+
+### [api.Trustable](https://godoc.org/github.com/ponzu-cms/ponzu/system/api#Trustable)
+Trustable provides a way for submitted content (via `api.Createable`) to bypass 
+the `editor.Mergeable` step in which CMS end-users must manually click the 
+"Approve" button in order for content to be put in the "Public" section and access 
+via the content API endpoints. `api.Trustable` has a single method: `AutoApprove` 
+which will automatically approve content, bypassing the "Pending" section 
+altogether.
+
+```go
+type Trustable interface {
+    AutoApprove(http.ResponseWriter, *http.Request) error
+}
+```
+
+##### Implementation
+```go
+func (p *Post) AutoApprove(res http.ResponseWriter, req *http.Request) error {
+    return nil
+}
+```
