Abstract
A system and method for using digitally signed web tokens to securely share sensitive data includes identifying an API request that includes an authorization header comprising authentication data; assessing the authentication data of the API request against a corpus of valid authentication data; identifying the authentication data as valid authentication data and a target entity that corresponds to the authentication data; obtaining a set of permissions associated with the target entity; generating a digitally signed protobuf web token that includes a representation of the target entity and a representation of the set of permissions associated with the target entity; and based on the generation of the digitally signed protobuf web token: adapting the API request to an adapted API request that includes a header component comprising the digitally signed protobuf web token; and transmitting the adapted API request to a target API-processing service.
