Rate limits
Limits protect the platform and your account. They're generous for normal traffic and you can request higher ceilings for production.
Defaults
Scope | Sandbox | Production (default) |
|---|---|---|
Token requests | 30 / min | 60 / min |
Express / C2B calls | 60 / min | 600 / min |
Read calls (status, balance) | 120 / min | 1200 / min |
When you're limited
You get
429withcode: rate_limitedand aRetry-Afterheader (seconds).Honour
Retry-After; add jitter so retries don't thunder back at once.Cache your access token (don't fetch one per request) — the single biggest cause of token-endpoint limiting.
Need more headroom?
Request a higher ceiling during go-live from the Developer portal — tell us your expected peak throughput.
