We are using the API to make modifications to VAST (redirect) Creatives. We first get the full current state, alter some properties (eg VastXmlUrl, name) and send the full creative back using the CreativeService UpdateCreatives method.
We noticed that the option "Allow multiple impressions from trusted server-side ad insertion (SSAI)" becomes unchecked after updating a creative this way through the API.
This setting/property is not present in the Creative API output, nor can I find a way to set it programmatically.
Additionally, the fact that this setting became unchecked is also not visible in the change history.
Our intention is to not modify anything on the creative apart from the properties we do want to change, this is undesired behavior.
Is there a way we can keep this setting as-is when making updates to the VastRedirectCreatives?
We are calling the SOAP API directly using node/JS, if that matters.
Thanks
