Rate limiting guideline

Last updated: Sept 12th, 12:25am
PayPal may temporarily apply rate limiting when detecting unusual or abusive traffic to ensure platform stability.
While no fixed rate limits are published, if your integration exceeds limits, you may receive an
HTTP 429 - RATE_LIMIT_REACHED error.
- Use webhooks instead of polling to receive updates.
- Reuse OAuth 2.0 access tokens until they expire to avoid unnecessary auth requests.
If rate limiting affects your integration, contact Merchant Technical Support.
