Bulkgrid uses API key authentication on every current endpoint.

Send the API key in x-api-key

What to avoid

  • Do not expose Bulkgrid API keys in browser code.
  • Do not treat the key as a bearer token.
  • Do not assume proxies preserve custom headers unless you control that path.

Common failures

401 Unauthorized

This usually means the x-api-key header is missing, malformed, or invalid. Example error shape:

Requests work locally but fail in production

Check these first:
  • the deployed service is using the right environment variables
  • the request is being sent to the correct Bulkgrid base URL
  • no gateway, CDN, or proxy is stripping x-api-key
Call Bulkgrid from your backend or worker layer, not directly from the browser.
