Pennylane Rate Limits

Pennylane API v2 enforces a fixed rate limit of 25 requests every 5 seconds, applied at the token level. For OAuth apps the limit applies per generated token; for developer (Company/Firm) tokens it applies directly to the token. Rate limiting is enabled on both production and sandbox and affects all endpoints. Exceeding the limit returns HTTP 429 with a retry-after header. All responses (including non-throttled ones) carry ratelimit-limit, ratelimit-remaining, and ratelimit-reset headers for proactive monitoring.

Pennylane Rate Limits is the machine-readable rate-limit profile for Pennylane on the APIs.io network, in the API Commons Rate Limits shape.

It captures 1 rate-limit definition, measuring requests.

Limit state is signalled in the retry-after, ratelimit-limit, ratelimit-remaining, and ratelimit-reset response headers, and an exhausted limit returns HTTP 429.

This profile was written by API Evangelist and has not been verified against a page the provider published; treat every limit as unconfirmed until a dated transcription replaces it.

The profile also includes 2 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Accounting, Invoicing, Fintech, Rate Limiting, and Quotas.

Policies

Token-Level Limiting
Limits are tracked per token (per OAuth-generated token or per developer token).
Backoff Strategy
Honor retry-after; use ratelimit-reset to schedule retries and implement exponential backoff with jitter.
