thirdPartyId parameter for media correlation

FastPix has introduced thirdPartyId as a new parameter in VOD, so you can attach your own identifier to any uploaded media. The value is opaque to FastPix and is echoed back on the get-media response and in every webhook payload tied to the media — making it straightforward to correlate FastPix media back to the corresponding row in your own MAM, CMS, e-commerce database, or other upstream system.

If you previously stored the FastPix media ID in your own database as the bridge between systems, you can keep doing that — thirdPartyId is purely additive.
