Scheduler

Scheduler is a free feature of the Scraper APIs that lets you automate recurring scraping and parsing jobs by creating schedules.

Check out the video tutorial below to learn more about Scheduler and how it works.

Step-by-step guide on automating your recurring scraping jobs using Scheduler

We advise using Scheduler together with the Upload to Cloud Storage feature. This way, you can set up your schedule and receive regular data updates in your storage without trying to fetch results from our system.

IMPORTANT: Scheduler is a powerful tool that can quickly raise your service bill. We advise testing it with a few job items and a limited number of repeats to ensure you get the correct data at the right intervals. Once that's established, you can stop the test schedule and create a new, scaled-up schedule.

Quick Start

When creating a new schedule, follow the simple steps below.

1. Tell us how often we should repeat the jobs by submitting a cron schedule expression;

2. Give us a bunch of job parameter sets that we should execute at scheduled times;

3. Let us know when to stop by submitting an end time.

See here to find a code example for submitting a new schedule.

NOTE: You can also download and import this Postman collection to try out all our Scheduler endpoints. New to Postman? Learn more about this tool here.

Endpoints

Scheduler has several endpoints you can use to control the service:

• Create a new schedule

• Get all schedules

• Get schedule information

• Deactivate or reactivate a schedule

Create a new schedule

Overview

Use this endpoint to initiate a new schedule.

• Endpoint: https://data.oxylabs.io/v1/schedules

• Method: POST

• Authentication: Basic

• Request headers: Content-Type: application/json

Input

Parameter	Description	Default Value
cron	Cron schedule expression. It determines how often the submitted schedule will run. Read more here and here.	-
items	List of Scraper APIs job parameter sets that should be executed as part of the schedule.	-
end_time	The time at which the schedule should stop running. NB: the end time is inclusive.	-

- required parameter

NOTE: For guidance on putting together job parameter sets for the items part of your Scheduler payload, refer to the documentation page of the particular scraper you would like to use (e.g. Google, Amazon, etc.).

The payload below will make Scheduler run two jobs schedule at 03:00 on Mondays until end_time (inclusive).

{
  "cron": "0 3 * * 1",
  "items": [
    {"source": "universal", "url": "https://ip.oxylabs.io"},
    {"source": "google_search", "query": "stuff"}
  ],
  "end_time": "2032-12-21 12:34:45"
}

Output

The response below confirms that the schedule was created successfully.

{
    "schedule_id": 4134906379157007223,
    "active": true,
    "items_count": 3,
    "cron": "0 3 * * 1",
    "end_time": "2032-12-21 12:34:45",
    "next_run_at": "2022-06-06 10:15:00"
}

Get all schedules

Overview

NOTE: Currently,items (i.e., the jobs to be executed as part of a schedule) are missing in the output. We are aware of this and will add them shortly.
