What is Asynchronous Web APIs in Magento 2.3?

Question

In Magento Open Source 2.3.0 Release Notes

Magento introduced Asynchronous web endpoints in Release Notes.

Example

PUT /async/V1/products/24-MB01

payload

{
  "product": {
    "price": 29
  }
}

1. Isn't it same with normal API call ?
2. And is it related to GraphQL ?

Answer 1

Asynchronous Web APIs

The only difference with synchronous calls (you can say Normal API call) is

The route to all asynchronous calls contains the prefix /async, added before /V1 of a standard synchronous endpoint.

Logical difference

Asynchronous and bulk web APIs will process API calls without waiting for the whole call queue to be processed. Using this approach greatly reduces the response time from the APIs while processing such API calls as bulk product integration, or customer import. This functionality will be available in both Magento 2.3 Commerce and OpenSource editions.

For GraphQL

• GraphQL is a query language for APIs. It is one of the modern technique to build and query API.
• Magento 2.3 executes GraphQL as an elective API endpoint in addition to REST API and SOAP API.

I hope this will help. I tried to cover all your question query
