Flickr Push API

openapi: 3.2.0
info:
  title: Flickr Activity Push API
  description: 'The Flickr API exposes the photo, group, people, place, tag, gallery, and

    photoset capabilities that power flickr.com. Almost all flickr.com

    functionality is reachable through a single REST-like endpoint

    `https://api.flickr.com/services/rest` using a `method=flickr.{namespace}.{method}`

    query parameter and `format=json&nojsoncallback=1` for JSON output.


    This OpenAPI specification models a curated set of the most widely used

    methods across the Flickr API''s 250+ method namespaces (activity, auth,

    blogs, cameras, collections, commons, contacts, favorites, galleries,

    groups, groupsDiscuss, interestingness, machinetags, panda, people, photos,

    photos.geo, photos.licenses, photos.notes, photos.transform, photos.upload,

    photosets, places, prefs, profile, push, reflection, stats, tags, test, urls).


    Authentication is API key + OAuth 1.0a (HMAC-SHA1). Commercial use of the

    API requires prior permission from Flickr.
