COMMON QUESTIONS

Frequently Asked Questions About API Integrations & Backend Services.

Clear answers to help you plan your project scope and expectations with confidence.

We implement idempotent queue architectures with exponential backoff retries. If an external API is down, the request is safely held in a queue and re-attempted automatically once the service restores, preventing any data loss.

Yes. We configure your Meta Business Manager, register your phone number, set up verified message templates, and build the webhook handlers to send and receive messages automatically.

It depends on the third-party provider. Most services (like Razorpay or Shiprocket) have free API access with standard transaction fees. We help you choose the most cost-effective tier for your scale.
