Secure communications via third-party systems through frames

A method implemented by a partner computing system, the method comprising:

• receiving, from a service provider computing system, an SDK component which incorporates into a website to facilitate secure communication between a user device and the service provider computing system via a frame in the website;
• accepting via the SDK component a request for an SDK session token in response to a user input submitted via the website being accessed via the user device;
• obtaining the SDK session token from the service provider computing system via an authentication API call transmitted to the service provider computing system to request the SDK session token;
• and
• providing the SDK session token to the SDK component to allow the user to have authenticated private communications with the service provider computing system via an inline frame in the website.

A partner computing system comprising:

• a network interface configured to communicate via a telecommunications network;
• and
• a processor and a memory having stored thereon instructions that, when executed by the processor, cause the processor to:
• present information to a user device via a website that utilizes an SDK component to facilitate secure and private communication between a user device and a service provider computing system;
• receive, via the SDK component, an HTTP request for an SDK session token, the SDK component having generated the HTTP request in response to a user input submitted to the web site;
• transmit an authentication API call to the service provider computing system to request the SDK session token;
• receive, in response to the authentication API call, the SDK session token from the service provider computing system;
• and
• transmit the SDK session token to the user device to enable authenticated communications directly between the user device and the service provider computing system via the SDK component.
