  • Important: Due to EU & UK Payments regulatory requirements, an additional security verification via Digital Signatures is required for certain API calls that are made by EU/UK sellers. Please refer to Digital Signatures for APIs to learn more on the impacted APIs and the process to create signature to be included in the HTTP payload.

  • OpenAPI Specification - Version 2.0 for all of our RESTful APIs will no longer be available starting April 5, 2023. We will continue leveraging OpenAPI Specification - Version 3.0 for new features in our RESTful APIs.

Note: For additional information about keypairs and creating Message Signatures, refer to Digital Signatures for APIs.
