Type

Requirement

Access Tokens

If querying an App-Scoped User ID:

Notes

Supports App-Scoped User IDs (ASID), User IDs (UID), and Page-Scoped User IDs (PSID).
By default this edge will return a 302 redirect to the image. To get data about the image, include the redirect=false query string parameter.
Profile picture URLs returned by this edge will expire.
Tokenless requests on ASIDs made by apps that are inactive or that have not completed Data Use Checkup will receive an error code in response.

Limitations

Apps in Development mode that make tokenless requests on ASIDs will receive a silhouette image in response.
Apps in Development mode that make requests with a Client token will receive a silhouette image in response.
