FEP-0ea0: Payment Links

Summary

This FEP describes a way to attach payment information to ActivityPub actors and objects. That information might be a link to donation page, a link for buying an artwork, or anything else that can be represented with a URI.

History

PeerTube videos may have support property, which contains a text explaining how to support the content creator.

FEP-8c3f: Web Monetization was published in 2022. The ensuing discussion on SocialHub forum led to the creation of this proposal.

Requirements

The key words “MUST”, “MUST NOT”, “REQUIRED”, “SHALL”, “SHALL NOT”, “SHOULD”, “SHOULD NOT”, “RECOMMENDED”, “MAY”, and “OPTIONAL” in this document are to be interpreted as described in RFC-2119.

Payment link is an object with the following properties:

Payment links MUST be added to attachment array of an actor or an object.

Examples

Payment link attached to an actor:

{
  "@context": "https://www.w3.org/ns/activitystreams",
  "type": "Person",
  "id": "https://social.example/users/alice",
  "inbox": "https://social.example/users/alice/inbox",
  "outbox": "https://social.example/users/alice/outbox",
  "attachment": [
    {
      "type": "Link",
      "name": "Donate",
      "href": "payto://iban/DE75512108001245126199",
      "rel": "payment"
    }
  ]
}

Payment link attached to an object:

{
  "@context": "https://www.w3.org/ns/activitystreams",
  "type": "Image",
  "id": "https://gallery.example/photos/123",
  "attributedTo": "https://gallery.example/users/alice",
  "name": "Painting of a cat",
  "attachment": [
    {
      "type": "Link",
      "name": "Buy",
      "href": "https://gallery.example/photos/123/order",
      "rel": [
        "payment",
        "https://gallery.example/ns#buy"
      ]
    }
  ]
}

(This section is non-normative.)

Implementers may treat payment links attached to actor object in the same way as actor metadata fields. In that case, name translates into field label and href translates into field value.
