A method of authorizing a front-end device, comprising:

• receiving, from the front-end device, a request for a first token associated with the front-end device and derived from a secret associated with the front-end device;
• transmitting, to a token server, the request;
• receiving, from the token server, the first token in response to the request for the first token;
• transmitting, to the front-end device, the first token;
• determining an expiry associated with the first token;
• transmitting, to the token server, a request for a second token prior to the expiry associated with the first token;
• receiving, from the token server, the second token in response to the request for the second token;
• and
• transmitting, to the front-end device, the second token.

A non-transitory computer-readable medium storing a set of instructions for authorizing a front-end device, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a device, cause the device to:
• receive, from a front-end device, a request, including a token associated with the front-end device, to perform an action;
• verify the token;
• transmit, to an application programming interface (API) gateway, a request associated with the action based on the token being verified, wherein the request includes an identifier of the front-end device;
• receive, from the API gateway, an indication of a status of the action in response to the request associated with the action;
• and
• transmit, to the front-end device, a message indicating the status.
