This repository contains the documentation for the ActivityPub implementation on Flipboard.com.
If you are having issues with the ActivityPub implementation on Flipboard.com, please open an issue in this repository.
In the implementation of Flipboard's ActivityPub, the User-Agent HTTP header is utilized to identify the source of the request. The User-Agent string is formatted as:
Flipboard ActivityPub/1.0.0 (+https://flipboard.com)
All requests from the Flipboard ActivityPub implementation will include this User-Agent string.

The current webfinger implementation only supports JSON responses.
Flipboard accounts that are federated will return an "application/activity+json link in the webfinger response.
If an account is not federated, the webfinger response will not include an "application/activity+json link.
All active accounts will return a profile-page link in the webfinger response.
We follow the latest draft of the http signatures specification.
For GET requests the server will provide a signature in the Signature header that verifies the (request-target), date, and host headers:
Signature: keyId="https://flipboard.com/actor#main-key",algorithm="rsa-sha256",headers="(request-target) date host",signature="..."
For POST requests the server will provide a signature in the Signature header that verifies the (request-target), date, host, and digest headers:
Signature: keyId="https://flipboard.com/actor#main-key",algorithm="rsa-sha256",headers="(request-target) date host digest",signature="..."
