After that date, a request that sends `Linkedin-Version: 202511` gets an error response. Any ads reporting, campaign management or Thought Leader Ads integration still pinned to that header needs to move to a supported version first. Microsoft Learn lists 202610 (October 2026) as the latest version, supported until October 15, 2027. Migrating is usually a header change, but the versions between 202511 and 202610 include at least one response-format change and several new fields, so test before you switch.** Last checked: November 9, 2026, against LinkedIn's [versioning page](https://learn.microsoft.com/en-us/linkedin/marketing/versioning?view=li-lms-2026-10) , [migrations table](https://learn.microsoft.com/en-us/linkedin/marketing/integrations/migrations?view=li-lms-2026-10) and [recent changes log](https://learn.microsoft.com/en-us/linkedin/marketing/integrations/recent-changes?view=li-lms-2026-10) on Microsoft Learn. ## What exactly is sunsetting on November 16, 2026? LinkedIn versions its Marketing APIs monthly. Each version is identified by a `YYYYMM` value in the `Linkedin-Version` request header and is supported for at least one year. The deprecation notice on Microsoft Learn reads: "The Marketing Version 202511 (Marketing November 2025) will be sunset on November 16, 2026." Version Sunset date Status on Nov 9, 2026 202510 October 15, 2026 Deprecated 202511 November 16, 2026 Active, sunsetting 202601 January 15, 2027 Active 202610 (latest) October 15, 2027 Active Source: LinkedIn's API migration status table on Microsoft Learn. The table lists no 202512 version. ## Who needs to act? You need to act if you run or depend on software that calls LinkedIn's Marketing APIs with the 202511 header. That includes: - Agencies with in-house dashboards that pull LinkedIn ad analytics - Teams that sync LinkedIn campaign data into a warehouse or BI tool - Tools that report on Thought Leader Ads or boosted member posts - Internal scripts for audience uploads, conversions or lead sync If you only use a third-party tool, ask the vendor which version they call and when they moved. If you can't get an answer before November 16, plan for a reporting gap. ## What happens if you miss the date? LinkedIn's versioning FAQ says an error response is returned when a request uses a deprecated version header. It also says requests with no version header return an error, and the latest version is not applied by default. A missed migration does not quietly upgrade itself. Calls fail, and dashboards built on them stop updating. ## How to migrate from 202511 to a current version 1. **Find every place the header is set.** Search your code and configuration for `Linkedin-Version` and `202511`. Check scheduled jobs and serverless functions, which are easy to forget. 2. **Pick the target version.** LinkedIn recommends the latest version. On November 9, 2026, that is 202610, supported until October 15, 2027. 3. **Read the changes between versions.** LinkedIn's recent changes log lists every version. The items in the next section are the ones most likely to affect reporting. 4. **Change the header in a test environment.** LinkedIn's FAQ describes migration as updating the `YYYYMM` value, for example from `202501` to `202601`. 5. **Compare outputs.** Run the same report on both versions for the same date range before November 16 and compare field names and values. 6. **Ship and monitor.** Watch for error responses after the switch, and log the version in each request so the next migration is easier. ## Changes between 202511 and 202610 worth testing These are taken from LinkedIn's recent changes log. The log is the complete list; this is a selection for reporting and agency use. Version Change Why it matters 202605 `/memberCreatorPostsAnalytics` and `/memberCreatorVideoAnalytics` return `metricType` as a string instead of an object Listed as a breaking change. Parsers that expect an object will break. 202604 `/memberCreatorPostAnalytics` adds metrics including POST\_SEND, POST\_SAVE, LINK\_CLICKS, FOLLOWER\_GAINED\_FROM\_CONTENT and PROFILE\_VIEW\_FROM\_CONTENT New creator metrics for executive and employee posts 202608 `/conversions` adds MARKETING\_QUALIFIED\_LEAD and SALES\_QUALIFIED\_LEAD conversion types Deeper funnel reporting and optimization 202609 `accountIntelligence` can filter by campaign group, objective type or member seniority Seniority breakdown of engaged accounts 202609 `/adAnalytics` supports a Nielsen DMA pivot Requires a DMA® notice when displayed 202610 `/adAnalytics` adds `memberFollows` and `memberProfileClicks` New Thought Leader Ads metrics, below 202610 `accountIntelligence` can filter by job function (LAST\_90\_DAYS only) Job-function breakdown of engaged accounts 202610 Boost API endpoints for member and Company Page posts Partners can embed boosting in publishing tools 202610 `/creatives` adds a read-only `metadata` field One call returns headline, intro text and landing page One more date to note. LinkedIn's 202610 notes describe a required `surface` field for publisher lists starting with version 202611, with a migration window for existing partner accounts that ends December 15, 2026. If you manage publisher lists, put that date on the same plan. ## Which new metrics matter for Thought Leader Ads reporting? From 202610, `/adAnalytics` supports two optional metrics that LinkedIn says exist only for Sponsored Updates and member follower display ads, such as Thought Leader Ads: - **`memberFollows`**: the count of sponsored member profile follows - **`memberProfileClicks`**: the count of clicks on the profile of the member who owns the sponsored post For agencies running executive ads, these answer a question clients ask: did the spend grow the executive's audience, or only the post's reach? You only get them after migrating to 202610 or later, and only if you request them. Both are counts. They tell you how many people followed or clicked, and the API does not return who they were. If a client wants to follow up with the people engaging around an executive's content, that is a different job from ads reporting. Our guide to [LinkedIn Thought Leader Ads strategies](https://traxy.ai/blog/linkedin-thought-leader-ads-b2b-strategies) covers the format itself. ## Where traxy fits (and where it doesn't) traxy is not a LinkedIn ads reporting tool, and this migration does not involve it. If you use traxy alongside your ads stack, the jobs stay separate: - **Marketing API reporting** gives aggregate counts for campaigns and sponsored posts. - **traxy** finds qualified people from LinkedIn engagement on the profiles and posts you track, scores each one against your lead criteria, and shows the recorded signal ([how qualification works](https://docs.traxy.ai/discovery/qualification) ). For example, if an executive's organic posts are getting traction, you can track the executive's profile in traxy with a Teammate relationship and review who engages and fits your criteria. For older posts, submit the post URL as a tracked post ([tracking](https://docs.traxy.ai/discovery/tracking) ).

No. On November 9, 2026, Microsoft Learn lists 202610 (October 2026) as the latest version. ### How long is each LinkedIn Marketing API version supported? LinkedIn says monthly versions are supported for a minimum of one year. The migrations table lists each version's sunset date. ### Can I skip to the newest version directly? Yes. LinkedIn says you can migrate to any later version, and recommends the latest so you can wait up to a year before migrating again. ### What if my request has no version header? LinkedIn's FAQ says an error response is returned. The latest version is not applied by default. ### Where do I ask LinkedIn about migration problems? The deprecation notice points to the LinkedIn Developer Support Portal. ## Next step Search your codebase for `202511` today, and list every vendor that touches your LinkedIn ads data.
