  BREAKING: OAuth Redirect Flow redirect with errors

  Action required Update

  In the OAuth redirect flow, the client typically has the ability to process error messages if they are returned as a query parameter to the redirect URL (see OAuth RFC: https://tools.ietf.org/html/rfc6749#section-4.1.2.1).
  
  Until today this was unfortunately not possible and error messages were displayed directly in Zaikio. With this change it is possible to handle the error by yourself.
  
  In case of an error, the redirect URL will be redirected in the following way: {REDIRECT_URL}?error={error_id}&error_description={optional description} Possible Errors:

  • invalid_request: Usually related to invalid PKCE
  • access_denied: The user cancelled the redirect flow intentionally
  • invalid_scope: The scopes provided were invalid, the error description contains details about the invalid scope (see Scopes)

  This change affects the Zaikio OAuth redirect flow. On June 15, 2021, this change will be rolled out to everyone on a mandatory basis. Until then, the new logic can already be used via an optional parameter (https://hub.zaikio.com/oauth/authorize/?redirect_with_error=1&client_id=...) to enable a smooth transition. For all new apps created from now on, the new logic already applies. Many OAuth client libraries will probably already handle this behavior, so we recommend just trying the parameter.

  Changes to Variant paper_weight_unit value

  Action required Update

  We are going to change the Variant property paper_weight_unit on 2021-03-04:

  • basis weight will no longer be supported as a value - Any existing fields set as grammage will be converted to the equivalent metric unit gsm - gsm will be the only accepted value when creating or updating Variants from this date If you are creating or updating Variants now, please set paper_weight_unit to gsm and be prepared to handle this value in any API response which includes Variant information.

  BREAKING: /connections and /subscriptions

  Action required Update

  The API endpoints GET /connections AND GET /subscriptions will introduce pagination. The reponse will include following Headers:

  • Link Links to previous and next pages, in the format described in RFC 8288 The relations first, prev, next and last can be present.
  • Current-Page The current page of the paginated response (starting at 1)
  • Total-Count The total number of items in this collection
  • Total-Pages The total number of pages for the current page size in this collection
    
    and following query parameters will be accepted:
    
  • page The page of the current collection that shall be returned (starting at 1)
  • per_page The maximum number of items included in the response, ie., the page size (100 by default)
    
    Furthermore it is also possible to provide a filter on GET /subscriptions:
  • filters[subscriber_id] e.g. Organization-d2e78ba7-5cfc-4359-9d8a-43ce0fa3a795
    
    and on GET /connections:
  • filters[connectable_id] e.g. Organization-d2e78ba7-5cfc-4359-9d8a-43ce0fa3a795

  DEPRECATED: site_id in machines

  Action required Update

  The site is now part of machine ownership and should therefore be set together via machines/{machine_id}/ownership. That is why we now also offer a PATCH machines/{machine_id}/ownership so that the site ID can be changed.
  
  We will allow the site to be set in the machine until April 6, 2020. After that, setting the site will only be possible in the ownership.

  OAuth Credentials: Name and description

  New Update

  From now on, a non-public description can be added when creating or modifying OAuth credentials.
  
  In addition, a name with a maximum of 4 characters can optionally be added. This extends the audience (aud) of the JSON Web token. If the audience was my_app it can now also be my_app/{credentials_name} if a name is given. The name must be unique within your app. However, other apps may have the same name, so you need to check the app name as well.
  
  If you want to test your JWT, try our interactive JWT Verifier.

  In Redirect Flow and Device Flow an organization can be pre-selected

  New Update

  It is now allowed to pass an Organization ID in Redirect Flow and Device Flow, so the user does not have to select the organization in Zaikio.
  
  The organizational ID is then passed as a scope as in Client Credentials Flow. For example:
  Org/5345a2a-8786-5b46-a1e2-516658fde390.directory.organization.r
  
  It is only possible to set organizations where the current user is also the admin.

  API returns if email of person was confirmed

  New Update

  We already return the email in our API. In addition, there is a new attribute email_confirmed, which indicates whether the user has confirmed the given email. No emails should be sent or the identity should be confirmed based on an email as long as this email has not also been confirmed.

  Person Bearer: Restrictions on sites and machines

  Action required Update

  If you use an Access Token with Person Bearer, it is no longer possible to perform every action for security reasons. If the bearer is a normal member of an organization (not an admin) then it is no longer possible:
  
  - POST /machines​/{machine_id}​/machine_ownership
  - POST /sites
  - PATCH /sites/{site_id}
  
  If these requests now fail a 403 Forbidden is returned. Every other endpoint works as before. If an admin is the bearer, there is no change.

  First name can be null

  Action required Update

  Since many countries do not have first names, we are now making this field optional for all members. This means in the API response the first_name can be null. We recommend to always use the full_name to display a name.

  New: Create Organizations

  New

  It is now possible to create new organizations with a Person Access Token. For this purpose the new scope directory.organizations.w is required. The current user will then automatically become the owner of the organization.
  
  In addition, the app that issued the token will connect directly with desired OAuth Scopes and Event Subscriptions from the directory. This means that after creation you can directly request an Organization Access Token via the Client Credentials Flow.

  New: sites read OAuth Scope

  New Update

  The directory now offers a new OAuth Scope called directory.sites.r which can only read information from the sites.
  
  A new endpoint has also been added to return information of a single page (/api/v1/sites/{site_id}).
  
  Also, addresses can now be retrieved for each site if they have been added.
  
  Furthermore, the site_id is now also returned for the machines, if a site has been assigned to the machine.

  Users can not connect to foreign and unreviewed Apps in production

  Action required Update

  It is no longer allowed for users to connect to any App in production environment. As the zaikio platform we have to make sure that all apps comply with our security standards and that malicious apps do not connect.
  
  However, organizations and members can connect to self-created apps at any time (i.e. the vendor is the own organization). In addition, all apps can connect in the sandbox environment, since no sensitive data is stored there.
  
  In order for your app to be available in production, you have to bring your app into the review process (this can be done on the detail page of your app). In order for us to activate the app, however, it should be usable (i.e. you provide a redirect flow and/or an API with appropriate documentation). For this purpose we will contact you.

  New connections endpoint and connected attribute

  New

  It is now possible to retrieve all connections for an app. To do this, a GET request must be made to /api/v1/connections or /api/v1/connections/Person-abc-def-ghi. This request must be authenticated by Basic Auth (the Client Id must be the username and the Client Secret the password, this is only possible if the credentials are confidential).
  
  Additionally, there is the connected attribute in all API replies sent. So it is for example possible to see via a GET /api/v1/person request which organizations of the person are already connected to the app that requested the access token. Please check the Zaikio Hub API Reference for more details.

  Event Webhook URL is now managed in the App configuration

  Action required Update

  In the past each Event Subscription had to define its own Webhook URL. Now each App needs to define only one Webhook URL in its configuration and this Webhook URL will be used to deliver all Events.
  
  Note: At the moment this Webhook URL is only required when you want to add an Event Subscription to your App. In the future there will be events types that sent to all Apps and Apps will not need to explicitly subscribe to these event types. Therefore we will need to require all Apps having a Webhook URL soon.

  Client Credentials Flow: The bearer must first grant access to the app

  Action required Update

  Requested scopes by the Client Credentials Flow must be granted beforehand, otherwise the scope error ungranted_scope (see scope errors) will be returned.
  
  This means that the person or organization must have successfully accepted the scopes in advance through a Redirect Flow (or through the Device Flow) for this app.
  
  This authorization can also be done later directly through the Zaikio Hub App (via Connections), if the App has been approved by the Zaikio Team. If you want to participate, please contact us directly.

  OAuth Scopes in directory are limited to certain bearer types

  Action required Update

  As documented in the Zaikio Hub API Reference these directory some scopes will only be available for certain Bearer types (otherwise an unavailable_scope_for_bearer_type error will be returned):
  
  directory.person.r => only for Person
directory.organization.r, directory.organization_members.r => only for Organization
  
  This does not change the functionality, as these scopes will not work with another Bearer type.
