# Creative preview support

> See which ad platforms provide authoritative creative previews and when Interchange fails closed.

Interchange uses a platform's own preview when one is available. These previews
show how the platform renders a creative for a placement; they do not guarantee
approval or delivery.

<Warning>
  Preview links are provider-hosted and may expire. Interchange returns them as
  links and never executes provider-supplied embed code in its surfaces. When a
  safe image thumbnail is available, Interchange shows the actual creative
  inline and keeps the authoritative platform rendering behind the link.
</Warning>

See each platform's compatibility page for its wider creative and campaign
support.

## Meta preview boundary

Meta preview requests use the ad account selected on the Interchange
connection. If the source creative has already been synchronized, Interchange
resolves its Meta creative ID from that advertiser and account's creative
record, then verifies the creative still reads back under the selected account.
Meta preview links are treated as expiring after five minutes; use **Refresh**
to request a new link after that deadline.

For an unsynchronized image manifest, Interchange can submit a read-only
transient specification. Other unsynchronized creative types must be synced
before previewing. A request fails closed when the creative identity, account,
format, or requested placement cannot be verified.

The response contains one or more HTTPS Meta preview links, labeled by
placement. Creatives already synced to Meta may also include a provider-readback
image thumbnail; transient previews remain link-only. Interchange does not
return executable preview HTML.

## Reference-renderer fallback

First-party platform previews remain authoritative. A future community
reference renderer may provide a clearly labeled approximation for supported
canonical image and carousel formats when a platform preview is unavailable.
Until that fallback ships for an adapter, the adapter does not advertise
`preview_creative`; unsupported requests fail closed. Shared creative-generation
adapters follow the same boundary: they do not advertise `preview_creative`
until an ephemeral preview store can enforce the link's advertised lifetime.
