ProcessOut · Rate Limits

Processout Rate Limits

ProcessOut enforces three independent rate limits using a Generic Cell Rate Algorithm (GCRA) token bucket per project, specified in requests per minute (RPM). Exceeding the bucket returns HTTP 429. Every API response carries the x-ratelimit (the project's limit) and x-ratelimit-remaining (remaining bucket capacity) headers. Values are allocated per project and may be changed by ProcessOut at any time.

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

It captures 1 rate-limit definition.

Limit state is signalled in the limit and remaining response headers.

Tagged areas include Payments, Payment Orchestration, Smart Routing, Tokenization, and Checkout.
