Which statement about the differences between instant and polling triggers is true?

Understanding Instant and Polling Triggers:

Instant Triggers:

Rely on webhooks to receive real-time data from a third-party system.

The external system sends a notification (webhook) to Fusion whenever an event occurs, triggering the scenario immediately.

Polling Triggers:

Regularly check (poll) the third-party system for new or updated records at scheduled intervals.

These are slower because they involve repeated API requests.

Why Option B is Correct:

Speed and Efficiency:

Instant triggers process data faster because they act immediately upon receiving a webhook. Polling triggers, on the other hand, may take time depending on the polling frequency and can result in unnecessary delays.

Reduced Load on Systems:

Instant triggers generate fewer API calls than polling triggers, which continuously check for new records even if no changes have occurred.

Best Practice: Use instant triggers whenever supported by the third-party system to ensure faster and more efficient scenario execution.

Why the Other Options are Incorrect:

Option A ("Instant triggers store received webhooks in a queue"):

Webhooks do not store data in a queue; they simply notify Fusion of events in real-time. Polling triggers also do not store records but remember the last processed record.

Option C ("A user must set up a webhook in Fusion"):

Instant triggers require setting up webhooks in the external system, not in Fusion. Fusion provides the webhook endpoint, but the user must configure the source system to send data.

Option D ("Only polling triggers can be set to run on a schedule"):

This is incorrect because instant triggers do not rely on schedules; they operate in real-time. Polling triggers, however, run on schedules and are used when instant triggers are unavailable.

Instant triggers are the preferred option when available, as they provide real-time data processing with greater speed and efficiency than polling triggers.
