Proctorio Rate Limits

Proctorio does not publish numeric rate limits for its v2 integration API or its result webhooks. The launch API is called once per exam session (to mint a signed candidate, reviewer, or live URL) rather than in high-volume automated loops, so effective throughput is governed by exam volume and the terms of the partner/institution agreement rather than by a documented per-minute request cap. Result webhooks are emitted once per submitted attempt (and can be re-emitted from the Review Center). Signed launch URLs carry an expiry (default 18000 seconds in the official client) which bounds how long a minted URL is valid.

Proctorio Rate Limits is the machine-readable rate-limit profile for Proctorio on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 4 rate-limit definitions, measuring requests, seconds, events, and exams.

The profile also includes 3 backoff/retry policies defined and response codes documented for throttled.

Tagged areas include Online Proctoring, Exam Integrity, Assessment, Rate Limiting, and Quotas.

Policies

Signed Request Auth
All launch requests are HMAC-signed with the Proctorio-provisioned consumer key and secret; unsigned or invalid requests are rejected.
URL Expiry
Signed launch URLs expire after the configured window and must be regenerated.
Backoff Strategy
Integrating platforms should implement exponential backoff with jitter and honor Retry-After on any 429 responses.
