Which type of integration would you choose for this scenario and why? 5000 requests per day load.

For a load of 5000 requests per day (about 3-4 requests per minute), the optimal choice would be to use synchronous REST API integration. This type of integration is simple to implement, scales well under moderate load, and provides quick response times.

If high reliability and asynchronous processing are required, message queues (such as RabbitMQ or Kafka) can be considered, but for the specified load, this would be excessive.

In summary:

• REST API — suitable for 5000 requests per day
• Queues — for higher loads or asynchronous processes

The choice depends on the requirements for response time and reliability.
