How to Bulk Shorten URLs Using an API

Published: July 2026

Manually shortening links one at a time becomes impractical once you're dealing with hundreds or thousands of URLs, which is exactly the problem bulk shortening through an API solves.

When Bulk Shortening Makes Sense

  • Migrating an entire catalog of product links to a new tracking system.
  • Generating unique links for a large-scale influencer or affiliate campaign.
  • Processing links extracted from a large content archive or database.

How the Process Typically Works

Instead of sending one URL per request, many APIs support submitting a batch of URLs at once, or accept repeated automated calls in quick succession within your account's rate limits.

Preparing Your Data

Organize your long URLs, along with any desired custom slugs or tags, into a structured format like a spreadsheet or CSV file before beginning the bulk shortening process, making it easier to track results afterward.

Respecting Rate Limits

Most APIs impose limits on how many requests you can send within a given time period. Review these limits before starting a large batch job to avoid errors or temporary access restrictions.

Verifying Results

After a bulk shortening job completes, spot-check a sample of the generated links to confirm they redirect correctly before rolling them out across your live campaigns or systems.

Storing the Results

Keep a clear record mapping each original URL to its new shortened version, ideally including any relevant tags or campaign identifiers, so the bulk-generated links remain organized and easy to reference later.
