LinkedIn does not publish its per-app or per-member limits and returns 429 when you reach them. Member tokens last 60 days and cannot be refreshed without a partner agreement, so expect to reconnect every two months.

- Every 60 days. Xairo warns you a week before it lapses.

Worth knowing
- LinkedIn refuses http redirect URLs, so its sign-in comes back through xairoapp.com rather than straight to the app.
- Every call names the API version it was written against; LinkedIn supports each version for about a year.
