> ### Contexts are now available > > After you have upgraded your LaunchDarkly SDK to use contexts instead of users, you should use [Update expiring targets for segment](https://launchdarkly.com/docs/api/segments/patch-expiring-targets-for-segment) instead of this endpoint. To learn more, read [Contexts](https://launchdarkly.com/docs/home/observability/contexts). Update expiring user targets for a segment. Updating a user target expiration uses the semantic patch format. To make a semantic patch request, you must append `domain-model=launchdarkly.semanticpatch` to your `Content-Type` header. To learn more, read [Updates using semantic patch](https://launchdarkly.com/docs/api#updates-using-semantic-patch). If the request is well-formed but any of its instructions failed to process, this operation returns status code `200`. In this case, the response `errors` array will be non-empty. ### Instructions Semantic patch requests support the following `kind` instructions for updating expiring user targets. <details> <summary>Click to expand instructions for <strong>updating expiring user targets</strong></summary> #### addExpireUserTargetDate Schedules a date and time when LaunchDarkly will remove a user from segment targeting. ##### Parameters - `targetType`: A segment's target type, must be either `included` or `excluded`. - `userKey`: The user key. - `value`: The date when the user should expire from the segment targeting, in Unix milliseconds. #### updateExpireUserTargetDate Updates the date and time when LaunchDarkly will remove a user from segment targeting. ##### Parameters - `targetType`: A segment's target type, must be either `included` or `excluded`. - `userKey`: The user key. - `value`: The new date when the user should expire from the segment targeting, in Unix milliseconds. - `version`: The segment version. #### removeExpireUserTargetDate Removes the scheduled expiration for the user in the segment. ##### Parameters - `targetType`: A segment's target type, must be either `included` or `excluded`. - `userKey`: The user key. </details>
