Mergent provides a developer-focused API for managing background tasks and schedules. It enables reliable execution of asynchronous jobs, including one-off tasks triggered by events and recurring schedules defined by cron expressions or rrules. Designed for simplicity, the service integrates via HTTP webhooks and offers monitoring tools.
Tasks handle individual, one-off workloads outside the main application flow. Examples include processing user sign-ups or purchases. Once queued, Mergent ensures delivery with automatic failure retries. Tasks can execute immediately, after a delay, or at a specific time.
Schedules manage recurring jobs at customizable intervals, such as daily reports or weekly newsletters. They use cron or rrule syntax for precision, like every minute or third Tuesday monthly. Schedules trigger tasks processed identically to manual ones.
