Build and manage Web APIs using PHP and Google Cloud Endpoints

With the popularity of Web APIs, more and more enterprises and developers are beginning to use them to build applications. However, building and managing a Web API is not a simple task. In this article, we'll cover how to use PHP and Google Cloud Endpoints to easily build and manage web APIs.

1.What is Web API?

Web API refers to a way that allows applications to communicate with each other. By using Web API, developers can connect applications with other applications or services. Common Web APIs include REST (Representational State Transfer) and SOAP (Simple Object Access Protocol).

2. Why use Google Cloud Endpoints?

Google Cloud Endpoints is part of Google Cloud Platform, allowing developers to easily build, deploy and manage Web APIs.

Use Google Cloud Endpoints to enjoy the following benefits:

• Automatically generate API client library
• Provide API key-based authentication
• Automatically generate API documentation

3. Build a Web API using PHP and Google Cloud Endpoints

In this article, we will build a simple Web API using PHP and Google Cloud Endpoints. First, we need to set up a Google Cloud Endpoints API.

Enter Google Cloud Console and select APIs and Services > Library. Enter "Cloud Endpoints" in the search bar and select "Cloud Endpoints API Management."

Next, we need to create a project so that we can set up our API. In the Cloud Console's top menu bar, click "Select a Project" and select "New Project."

Then, we need to define the endpoint specification of the API. The endpoint specification is the declaration method of the API, including the format, parameter list, interface and method of the request (request) and response (response). We can define our endpoint specifications using the OpenAPI specification.

Next, we will generate our API classes from our OpenAPI files.

We need to install the google/cloud-endpoints-v1 library. Enter the following command in the console:

composer require google/cloud-endpoints-v1

Next, we will use the following command to generate the API class:

vendor/bin/endpoints-framework-generator openapi_spec.yaml

This will automatically generate the API class in which we can add relevant business logic.

4. Manage Web API

Once we build the Web API, we need to manage it. Google Cloud Endpoints provides the following features to help us manage APIs:

• API management backend: where we can view API metrics and logs
• API key management: we can use API Key Authentication to protect our API
• API Documentation: We can automatically generate and publish API documentation

5. Conclusion

Using PHP and Google Cloud Endpoints, we can easily build and manage our web API. Using Google Cloud Endpoints can help us generate API client libraries, provide API key-based authentication and automatically generate API documentation, making Web API management easier.
