AWS-SQS
AWS SQS Plugin – Subscribe (Trigger)
Summary (SEO Meta Description):
The AWS SQS Subscribe Trigger in WeHub listens for new messages from an Amazon SQS queue and automatically starts a workflow.
Configure the queue URL, FIFO options, and message attributes to integrate AWS queue-based systems with workflows.
Overview
The AWS SQS Subscribe Trigger allows WeHub workflows to automatically consume messages from an Amazon SQS queue.
It supports both standard queues and FIFO queues, with optional message attributes for fine-grained filtering and routing.
This makes it ideal for event-driven processing, asynchronous workloads, and decoupling microservices.
