Hello Carey, Chad,
The @odata.mediaEtag
is a property used in the Microsoft Graph API to handle caching and track changes for user photos. Let me explain further:
When you retrieve a user’s photo using the Graph API, you receive an ETag response header. This ETag represents a unique identifier for the photo data.
- Instead of fetching the entire binary image photo data each time, you can request the metadata of the photo. Specifically, you can use the following API call:
GET /users/{user-id}/photo
- The ETag allows you to check if the photo has changed since your last request. If the ETag remains the same, the photo content hasn’t been modified. If it changes, you know that the photo has been updated.
In summary, the @odata.mediaEtag
property helps efficiently manage photo data by allowing you to track changes without fetching the entire image every time.
