Rate Limits

Use this when you need to know how the API treats high call volume or when you get a 429. Limits are per environment and per client; your B1Link administrator has the exact numbers.

What to do​

  • Throttle callbacks — Do not send a large burst of vendor-number PUTs in a short period.
  • On 429 — Back off and retry; use exponential backoff. Log so you can see repeated rate limiting.
  • Limits or increases — Contact your B1Link administrator for your environment’s limits and for increase requests.
