Your users authorize your application to access their ATS platform by going through an authorization flow using Merge Link.

Utilize Merge's GET /jobs endpoint to programmatically pull all job requisition that exist within your customers' ATS platform.

There may be additional custom fields your customer wants to be surfaced for open jobs. This will be in the Field Mapping section within the Jobs Object.

On the initial pull from Merge, you can filter to only pull Jobs that are currently Open during that point in time.

Moving forward, you can pull job requisition updates from the ATS system to ensure you are keeping an accurate list of open job requisition for your customers.

After identifying the specific jobs and relevant information the customer wants to surface, you can build a frontend experience to show open requisitions in your product. Now your customers' open job listings are automatically pulled and surfaced.
