2C2P Rate Limits

2C2P does not publish fixed numeric rate limits for the Payment Gateway (PGW v4.3) API. As a payment acquirer, throughput is governed by the merchant agreement, risk / fraud controls, and the underlying card scheme and alternative-payment-method processors rather than by a documented requests-per-second cap. Idempotency is anchored on a unique invoiceNo per transaction, and transaction results should be confirmed via the backend notification webhook and Payment Inquiry rather than by tight polling.

2C2P Rate Limits is the machine-readable rate-limit profile for 2C2P on the APIs.io network, conforming to the API Commons Rate Limits specification.

It captures 3 rate-limit definitions, measuring requests and invoiceNo.

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

Tagged areas include Payments, Payment Gateway, Southeast Asia, Rate Limiting, and Quotas.

Limits

PGW API Requests merchant
requests
not published
No fixed numeric request-rate limit is documented for the Payment Gateway API; governed by merchant agreement and risk controls.
Transaction Idempotency merchant
invoiceNo
unique per transaction
Each transaction is keyed on a unique invoiceNo; reusing an invoiceNo is rejected rather than double-charged.
Inquiry / Status Polling merchant
requests
not published
Prefer the backend notification webhook plus Payment Inquiry / Transaction Status over aggressive polling.

Policies

Backend Notification First
Rely on the server-to-server backend notification (backendReturnUrl) as the authoritative transaction result; use Payment Inquiry to reconcile rather than polling in a tight loop.
Backoff Strategy
Clients should implement exponential backoff with jitter and honor Retry-After on 429 responses.
Risk and Fraud Controls
Requests may be throttled or declined by 2C2P risk / fraud screening and by upstream scheme and APM processors independent of any request-rate cap.
