LinkedIn Marketing API version 202511 sunsets November 16, 2026
What changed
LinkedIn releases Marketing API versions monthly and supports each for at least one year. Version 202511 sunsets on November 16, 2026 and version 202601 on January 15, 2027, after which calls with those headers return an error. The announced date is the month version 202511 was released, since LinkedIn's pages give no separate announcement date for the sunset.
What it means
Integrations sending Linkedin-Version: 202511 must move to a newer version header before November 16, 2026; 202601 follows on January 15, 2027.
