Q1Domain Verified
In the context of the Looker Action Hub, what is the primary architectural benefit of a "Webhook Action" over a direct API integration for triggering external workflows?
Webhook actions offer inherently better security due to their stateless nature, reducing the attack surface.
Webhook actions can directly execute complex SQL queries on the target external system without intermediate Looker modeling.
Webhook actions provide a richer payload of Looker-specific metadata by default, simplifying data transformation for the external service.
Webhook actions decouple the Looker instance from the external service's direct availability, enabling asynchronous processing and fault tolerance.
Q2Domain Verified
When configuring a "Data Action" within the Looker Action Hub, what is the most significant implication of defining a "param" with `type: "query"` for passing data to an external service?
It guarantees that the entire Looker query result set will be sent as a single JSON object, regardless of size.
It allows the external service to dynamically fetch specific fields from the Looker query based on its own requirements.
It enables the external service to re-execute the original Looker query against the data source for real-time validation.
It optimizes data transfer by only sending the aggregated results of the query, not the underlying raw data.
Q3Domain Verified
A "Custom Action" in the Looker Action Hub is being developed to integrate with a proprietary CRM. The CRM requires a specific `Content-Type` header for incoming dat
It can be specified within the `params` definition for the action, using a `type: "header"` parameter.
How is this `Content-Type` header best managed within the Looker Action Hub configuration? A) It must be hardcoded within the custom LookML action's `label` parameter for all requests.
It is configured directly within the external CRM's settings to match what Looker sends.
It is automatically inferred by the Looker Action Hub based on the data format being sent.
