Service

To handle requests sent by Alexa, your web service must meet the following requirements:

• The service must be Internet-accessible.

• The service must adhere to the Alexa Skills Kit interface.

• The service must support HTTP over SSL/TLS, leveraging an Amazon-trusted certificate.
  • For testing, Amazon accepts different methods for providing a certificate. For details, see About the SSL Options.

  • For publishing to end users, Amazon only trusts certificates that have been signed by an Amazon-approved certificate authority.

• The service must accept requests on port 443.

• The service must present a certificate with a subject alternate name that matches the domain name of the endpoint.

• The service must validate that incoming requests are coming from Alexa.

Note: if you are using Apache HTTP Server to host your web service, use version 2.4.10 or later. Earlier versions of Apache HTTP Server send an "unrecognized name" warning if the server is not configured with a ServerName or ServerAlias in the configuration files. This prevents the Alexa service from sending the customer's request to your server. To address this, either upgrade to 2.4.10 or later, or add ServerName / ServerAlias to your server's configuration file.
