Get LinkedIn post reactors
Input
url optionalAlias for postUrl (accepted for compatibility — prefer postUrl).
limit optionalMaximum number of reactors to return. Default 200.
Default: 200postUrl optionalThe LinkedIn post's URL, e.g. https://www.linkedin.com/posts/<slug>-<id>-<code> or https://www.linkedin.com/feed/update/urn:li:activity:<id>/. Tracking/query params are fine — they're ignored.
Output
total requiredTotal number of reactions on the post (all reaction types combined), read from the post's own reactions-count control. 0 when the post has no reactions.
reactors requiredThe reactors, in the order LinkedIn lists them, capped by `limit`. A list shorter than `total` means `limit` was reached. Empty with total 0 means the post genuinely has no reactions — confirmed by the post's action bar having rendered while no reactions-count control exists. A post that renders neither is reported as an error instead.
