API limits: size queues without blocking the operation

Editorial illustration: API limits: size queues without blocking the operation

An integration may work in the demo and fail when volume grows. Request limits need to be included in the sizing, including peaks, reprocessing and other applications that share the same account.

How to evaluate this decision

Confirm current limits and policies in the provider's documentation. Differentiate allowed rate, competition and contracted volume. Define priority and acceptable waiting time per event. Repeating calls immediately after a refusal can worsen the queue; The resumption strategy must respect the response received and preserve the pending operation.

Criteria for comparing proposals

  • Capacity: Estimate normal volume, peak and recovery from an outage.
  • Queue: define priority, retention and visibility of delays for the operation.
  • Attempts: limit retry and forward persistent failures for analysis.

A scenario to discuss with the supplier

Hypothetical example: an initial load consumes all API capacity and delays new requests. Separating priorities or processing windows may be necessary to maintain business flow.

What to validate upon delivery

Test a sequence above instantaneous capacity and observe recovery. Check that there is no loss or duplication and that the panel distinguishes error from expected delay.

Prepare the conversation about the project

Take documented limits, volumes and operational deadlines to Quantum9. The proposal must explain how integration behaves when demand temporarily exceeds available capacity.
