-# X-Callback-URLs in Tusker
-
-Tusker supports inter-app-communication using the [X-Callback-URL standard](http://x-callback-url.com/).
-
-In short, requests are performed by opening the URL `tusker://x-callback-url/[request]` (where `[request]` is one of the requests listed below) with a variety of parameters.
-
-## Callbacks
-
-X-Callback-URLs support three types of callbacks: on success, on cancellation, and on error. Callbacks are specified as query parameters whose keys identify which callback (`x-success`, `x-cancel`, and `x-error`) and whose values are other URLs that should be opened to run the callback.
-
-Data is passed to callbacks by adding additional query parameters to the callback URL. The `x-error` callback always returns a description of the error in the `error` parameter. Other data is provided depending on the request.
-
-### JSON Responses
-
-By default, callback data is included in URL query parameters of the callback URL. If the `json=true` parameter is provided, the response data will be encoded as JSON, converted to [Base64](https://developer.mozilla.org/en-US/docs/Web/API/WindowBase64/Base64_encoding_and_decoding), and provided in the `response` query parameter of the callback.
-
-## Silent Requests
-
-Tusker X-Callback-URL requests can be performed silently, without user confirmation. Each source app requires user permission on the first attempted silent action.
-
-To perform a silent request:
-
-1. Provide the `silent=true` URL query parameter in the request.
-
-2. Specify the `x-source` parameter. It must be a (human interpretable) name of the source application/service. If `x-source` is not specified, the error callback will be invoked with the error message:
-
-```
-Cannot perform silent action without source app, x-source parameter must be specified.
-```
-
-3. Depending on the current permission state of the source app, one of several things will happen:
-   1. If the permission is **undecided** (i.e. the user has neither accepted nor rejected the silent action request), an alert will be displayed notifying the user that the source app has requested permission to silently perform actions. After the user either accepts or rejects the request, execution will continue with that permission state.
-   2. **Accepted**: the request will be carried out silently and the appropriate callback executed.
-   3. **Rejected**: the request will be performed with the confirmation UI, as if the `silent` parameter had been false/unprovided.
-
-The silent actions permission state of a given source app is not exposed in the callback.
-
-## Other Notes
-
-#### Instance-Local IDs
-
-Instance-local IDs are provided for many responses and accept in place of URLs/URIs/qualified names in many requests. When possible, instance-local IDs should be preferred requests using them can often be performed faster because there's no need to perform a search query or make requests to remote instances.
-
-#### Qualified Usernames
-
-Qualified username refers to the domain-qualified identifier of an account. For example, `shadowfacts@social.shadowfacts.net`. They do not include a leading `@`.
-
