Overview

Crawler Signatures let Layers authenticate its image crawler when fetching media from your Shopify store. Stores with larger catalogs may hit rate limits from automated requests crawling all of the catalog images. With HTTP signature headers attached, Layers fetches images more reliably and is blocked less often.

​
Configuration

  1. In the Layers dashboard, go to Settings → Shopify Sync.
  2. Under Crawler Signatures:
    • Enable Crawler Signatures
    • Signature-Input Header
    • Signature Header
  3. Click Save.
Notes:
  • When Crawler Signatures are enabled, both Signature-Input Header and Signature Header are required.
  • Use the exact values provided by Shopify.

​
How it works

When Crawler Signatures are enabled, Layers adds the following headers to image requests:
  • Signature-Input
  • Signature
  • A standard agent is also included to identify the request.
If a signed request fails (for example due to rate limiting or temporary errors), Layers automatically retries through a secure proxy. No action is needed.
