Are you getting Failed to Load API Definition in Magento 2 Swagger while developing a Magento 2 extension?
In this quick tutorial, we will resolve it.
Why Failed to Load API Definition?
An application programming interface (API) allows two programs and computers to interact with each other.
Magento extension developers create custom API to drive the data through various programs. Data is collected from the client and has to go and interact with several Magento elements.
For example: After taking the order, the order id and customer’s email address should be sent to various departments (sales, operation, marketing) to perform the next function. The connection is built through the API.
Quality Magento developers maintain the API coding standards. To do that, they have to add phpdoc in the file. phpDocumentor (phpdoc) is an open-source documentation generator written in PHP.
The phpdoc consists of code that looks like comments, but it does affect the output in API building.
For example: The absence of variable’s datatype in API phpdoc will generate failed to load API definition in Magento 2 swagger.
Let’s see how to solve it:
Solution to Failed to Load API definition in Magento 2 Swagger:

* @param mixed $mailId
* @return mixed
*/
