Platform Updates: Operation Developer Love

Platform Updates: Operation Developer Love:

Since last Wednesday's update, we published a Developer Spotlight on Fab.com, and then made the below changes:

New `photo_src` FQL Table

We launched the photo_src FQL table which returns all the source URLs for various sizes of a photo. Using photo_src FQL, you can retrieve images with the following dimentions: 960, 720, 480, 320, 180, 130, 75px.

The examples below shows how to get a photo’s source URLs that are greater than 480px in width.

SELECT src, width, height FROM photo_src WHERE 
    photo_id = 10150931418786729 AND width > 480

Here is the return for the query above:

[
  {
    "src": "https://fbcdn-sphotos-a.akamaihd.net/hphotos-ak-ash4/457873_10150931418786729_20531316728_11172208_1769228986_o.jpg", 
    "width": 2048, 
    "height": 2048
  }, 
  {
    "src": "https://fbcdn-sphotos-a.akamaihd.net/hphotos-ak-ash4/417314_10150931418786729_20531316728_11172208_1769228986_n.jpg", 
    "width": 960, 
    "height": 960
  }, 
  {
    "src": "https://fbcdn-sphotos-a.akamaihd.net/hphotos-ak-ash4/s720x720/417314_10150931418786729_20531316728_11172208_1769228986_n.jpg", 
    "width": 720, 
    "height": 720
  }
]

See photo_src documentation for details on how to use it, and example queries.

Default Page Tab Image for Page Tab Apps

We added the ability to add a default page tab image for you page tab app. To add the default image, go to the Dev App and edit Basic Settings for your app. You can change the Page Tab Image under the Page Tab section. You can upload a JPG, GIF, or PNG file. If the image is larger than 111x74 pixels, it will be resized and converted. File size limit is 5 MB. See screenshot below for the new section.

Best Practices

This week we published a series of product guides on creating and working with actions and objects. The purpose of these guides is to help product managers and developers understand the most effective ways to integrate with the Facebook Platform. Our goal is to complement our developer documentation by answering common questions and highlighting important aspects of the platform. These documents are both conceptual and tactical.

Upcoming Breaking Changes on May 2, 2012

As announced on the Roadmap and Developer Blog, the following changes are going into effect on May 2, 2012:

offline_access Permission Removal

The offline_access permission is deprecated and will be removed May 1, 2012. Until then, you can turn this change on or off using the "Deprecate offline access" migration.
Please see the Removal of offline_access Permission doc for more details.

Removal of group_type and group_subtype columns from group FQL table

We remove the group_type and group_subtype columns of the group FQL table. Please ensure that your apps are not utilizing these columns.

Removing support to claim Domains using Page ID - Originally scheduled for April 1st, 2012

We will remove the ability to claim domains with a Page ID. The recommended option for claiming domains is with an App ID or User ID and existing domains that have been claimed will continue to work fine. After claiming domains, owners are able to view insights or run Domain Sponsored Stories. See the Insights documentation for more on the updated domain claiming flow.
