<p>
For accessing a service, the application typically needs to
present credentials. The application can request the
credentials via GOA. First the application should invoke the
<a class="link" href="gdbus-org.gnome.OnlineAccounts.Account.html#gdbus-method-org-gnome-OnlineAccounts-Account.EnsureCredentials" title="The EnsureCredentials() method">Account.EnsureCredentials()</a>
method on the account object. If this succeeds, the
application can request the credentials using e.g. <a class="link" href="gdbus-org.gnome.OnlineAccounts.OAuthBased.html#gdbus-method-org-gnome-OnlineAccounts-OAuthBased.GetAccessToken" title="The GetAccessToken() method">OAuthBased.GetAccessToken()</a>
or <a class="link" href="gdbus-org.gnome.OnlineAccounts.OAuth2Based.html#gdbus-method-org-gnome-OnlineAccounts-OAuth2Based.GetAccessToken" title="The GetAccessToken() method">OAuth2Based.GetAccessToken()</a>
depending on what kind of credentials the account is using.
If the service returns an authorization error (say, the access
token expired), the application should call <a class="link" href="gdbus-org.gnome.OnlineAccounts.Account.html#gdbus-method-org-gnome-OnlineAccounts-Account.EnsureCredentials" title="The EnsureCredentials() method">Account.EnsureCredentials()</a>
again to e.g. renew the credentials.
</p>
<p>
On the other hand, if <a class="link" href="gdbus-org.gnome.OnlineAccounts.Account.html#gdbus-method-org-gnome-OnlineAccounts-Account.EnsureCredentials" title="The EnsureCredentials() method">Account.EnsureCredentials()</a>
ever fails, then the user will get notified that there is a
problem with the account so he can take actions to fix it.
Applications can listen to changes on the <a class="link" href="gdbus-org.gnome.OnlineAccounts.Account.html#gdbus-property-org-gnome-OnlineAccounts-Account.AttentionNeeded" title='The "AttentionNeeded" property'>Account.AttentionNeeded</a>
property to get notified when it's time to try accessing the
account again.
</p>
<p>
Note that the implementation for a provider may switch from
e.g. OAuth to OAuth2 in a newer release of GNOME Online
Accounts. Therefore, applications must never assume that the
<a class="link" href="GoaObject.html" title="GoaObject"><span class="type">GoaObject</span></a> for an account implements a fixed set of
interfaces.
