Token-based authentication for Global APIs including Canada

Date: Jan 2026

Summary

Canada now supports token-based authentication, aligning with the US and other markets. Sellers no longer need to use the digital signature method for authentication, making integrations simpler and more consistent.

What changed

  • Removed: Digital certification authorization method is no longer supported, as mentioned in the legacy authentication flow for Canada Marketplace.
  • New: Token-based authentication for Canada is required. Sellers must obtain and pass an OAuth 2.0 access token when making API calls.
  • Updated behavior: Existing integrations using the deprecated digital certification method must migrate to the new token system to maintain access.

Why it matters

  • Standardization: Token-based authentication significantly increases endpoint protection and reduces exposure of long-lived credentials.
  • Future compatibility: New features and API improvements will be released only under the token-based framework.

Next steps

  • Migrate to global APIs.
  • Review the token API documentation for step-by-step implementation details.
  • Validate all API calls in a sandbox environment using the new OAuth 2.0 authentication flow.
