Evaluation and validation of application programming interface requests and responses for microservices applications

A system comprising:

• one or more processors;
• a memory including instructions, that when executed by the one or more processors, cause implementation of a microservice architecture application comprising a plurality of services that interact to perform an overall application function, each of the plurality of services being an application program interface (API) performing a piecemeal function of the overall application function;
• and
• execution of the instructions by the one or more processors further cause the implementation of a plugin,
• wherein the plugin is enabled for an object associated with the microservice architecture application, and wherein the plugin is configured to:
• receive a message comprising message content, wherein the message is intercepted before reaching a service of the plurality of services;
• retrieve a configuration of the plugin, the configuration comprising an identifier for the service, a flag indicative of the plugin being enabled or disabled, a specification of a reference schema, an identifier of a validator that outputs a validation result indicative of whether the message content satisfies validation requirements of the reference schema, and a set of parameters for the validator;
• and
• transmit, upon a determination that the validation result is false, an error notification indicative of an error in the message, wherein the message is prevented from reaching the service.

A method comprising:

• linking an application program interface (API) gateway to a microservice architecture application including a plurality of services that interact to perform an overall application function, each of the plurality of services being an API performing a piecemeal function of the overall application function;
• installing a plugin at the API gateway that evaluates messages received at the API gateway, wherein the plugin is enabled for an object associated with the microservice architecture application;
• receiving a message at the plugin comprising message content, wherein the message is intercepted at the API gateway before reaching a service of the plurality of services;
• retrieving a configuration of the plugin, the configuration comprising an identifier for the service, a flag indicative of the plugin being enabled or disabled, a specification of a reference schema, an identifier of a validator that outputs a validation result indicative of whether the message content satisfies validation requirements of the reference schema, and a set of parameters for the validator;
• and
• transmitting, upon a determination that the validation result is false, an error notification indicative of an error in the message, wherein the message is prevented from reaching the service.
