By default, Content Composer uses HTTPS to encrypt the communication between third party applications and the MWS SOAP API endpoint.
You can also configure these communications to use HTTP.
Note: For security reasons, we recommend the use of HTTPS.
For information on how to configure HTTPS, see Enabling HTTPS for the MWS SOAP API Communication Channel.
For information on how to change the default HTTPS configuration to use the insecure HTTP protocol, see Enabling HTTP for MWS SOAP API Communication Channel.
