LinkedIn deadline · version 202511
LinkedIn Marketing API version 202511 is sunset on 16 November 2026
LinkedIn's migration table gives version 202511 (November 2025) a sunset date of 16 November 2026. The LinkedIn Marketing API, including the Posts API used to publish on Pages, is versioned with a monthly Linkedin-Version header; each version is supported for at least one year and LinkedIn applies no version by default. A tool or script still sending Linkedin-Version: 202511 must move to a version that has not been sunset before that date.
Official date: 16 November 2026. 8 days left (UTC).

FAQ
LinkedIn API version FAQ
What happens on the sunset date?
LinkedIn asks you to upgrade to a newer supported version before the older one is no longer supported, to avoid service disruptions. A call that still sends a sunset version is no longer supported.
Does LinkedIn apply the latest version automatically?
No. LinkedIn expects every versioned call to specify its version; the latest version is not applied by default.
How long is a version supported?
A minimum of one year, according to LinkedIn.
Which version should I use?
Any version that has not been sunset. The newest one gives the longest runway: its sunset comes at least one year after its release.
Is the Posts API affected?
Yes. It is documented inside the versioned Marketing API documentation and uses the same Linkedin-Version header.
