What is Authentication?

Authentication is a process by which the identity of the request sender is verified.

Overview of the authentication process

  1. The sender obtains the required credentials. For the Product Advertising API, the credentials are the access key ID and secret key.

  2. The sender submits a request with the credentials to the recipient.

  3. The recipient uses the credentials to verify the sender.

  4. If the credentials are valid, the request is processed, and response information is returned. If the credentials are invalid, the recipient rejects the request and returns an error message.
