Where you see it

  • Your server: more than 120 requests a minute from one integration or Plugchoice user.
  • Your app’s result: more than 30 link sessions started in a minute from one IP address.
  • Inside the hosted flow, which handles it:
    • more than 300 requests a minute in one link session;
    • too many Zaptec sign-in attempts;
    • too many claims (the title Too many claims).

What it means

You hit a rate limit. The Retry-After header says how many seconds to wait, when the limit sets one.

What to do

  • Wait Retry-After seconds before you retry.
  • Reuse your integration’s token for its hour instead of requesting one per call.
  • Poll GET /link-sessions/{link_session_id} every few seconds at most.
