### What is External API in WordPress? {#what-is-external-api-in-wordpress}


External APIs are designed in such a way that they can be used within an organization or by any person outside the organization who wants the interface access. These External APIs are accessible to External, Third-Party Partners. If a person wants to access these APIs they will require API Keys and security Tokens. When it comes to using External APIs in WordPress the most basic functionality is in which we need to fetch data from an external, third-party API provider and use this data to display on the WordPress website and process it further. This can be easily done by using our [Custom API for WordPress](https://plugins.miniorange.com/custom-api-for-wordpress) plugin in which hooks are provided, using which calls to External APIs can be made whenever required. these hooks can be integrated easily with the third-party plugins in WordPress like – Woocommerce, Wpforms, Gravity forms, Fluent forms, Elementor, Payment gateways, etc.

### Multiple ways by which you can Integrate External APIs into your WordPress Website. {#integrate-external-apis-into-your-wordpress-website}

**1. Directly Fetch data from a REST API endpoint provided by a third-party/external provider**

![external-provider](/blog/assets/2023/external-provider.webp)

To Directly fetch the data from an external API provider, you need to have a REST API Endpoint which will be provided by the third-party provider. Here a direct API call is made to the external API endpoint and if the request is validated then you get the required data in form of a response. Once this data is fetched, it can be used to display on your WordPress website. This is one of the easiest ways to fetch your data from a third-party application into WordPress using External APIs.


**2. Use External APIs to perform form submission events**
![submission-external-api](/blog/assets/2023/submission-external-api.webp)

Using External APIs in WordPress is useful when you want to perform certain operations like Register, SignIn, Delete users in WordPress and these changes must reflect in the third-party application/platform. These operations are possible by making an external API call to the third-party provider once an event is triggered or a form is submitted in WordPress. Events can be triggered when a form is submitted in WPforms, Gravity Forms, Elementor, Contact-form7 or any other forms.


**3. Integrate External REST APIs on Payment gateways**
![payment-gateway-apis](/blog/assets/2023/payment-gateway-apis.webp)

External APIs in WordPress can also be used to trigger API calls when a payment is captured by Third-Party payment gateways like PayPal, Stripe, Woocommerce etc. By using these API calls it is possible to update the user status, user’s membership level etc on the WordPress or third-party API provider based on the payment status and amount.


**4. Directly fetch and update product data in WooCommerce from a third-party inventory store in real-time**
![inventory-store-apis](/blog/assets/2023/inventory-store-apis.webp)

Using External APIs in your WordPress website you can easily fetch real-time data from an external, third-party API provider into Woocommerce to display data or products, External APIs can be called in the backend using the developer hooks to sync the real-time data with Woocommerce products/items feeds and can be displayed on your site.


### Benefits of using External APIs with payment gateways in WordPress: {#benefits-of-using-external-apis-with-payment-in-wordpress}

- It becomes possible for your customers to Directly pay and make transactions on your WordPress website itself. This means that your payment is just an API call away.

- It becomes possible for you to accept payments from multiple payment gateways like PayPal or Stripe. This is important because most customers prefer their personal choice of payment method and will appreciate it if they see one. So, once you have the payment status as completed, then you can update user’s data on the WordPress/third-party side like user membership levels, permission levels etc.


- API which these payment gateways provide flexibility to handle all types of transactions while still providing the security and resilience that your CFO business needs.


In miniOrange’s WP Custom REST API Plugin hook is provided for this external REST API endpoints integration and this hook can be embedded directly into the gateways and run only based on the transaction status.

What is External API for WordPress And How To Get Started Using It?


**Enable Jira 2FA for Customers and skip for Employees**

REST API is an application interface that allows an application to expose its resources securely to client applications. REST APIs let you securely integrate with Jira server or Jira data center by querying and modifying data in your Jira application. Since the rest APIs are open to the internet and anyone can use them to gain illegitimate access and modify sensitive resources, it is crucial to authenticate each API call made to the server.

**Authentication methods to Secure APIs are as follows:**
- Basic Authentication
- API Key Authentication
- OAuth 2.0 Authentication

We will learn about them briefly below.

### Basic Authentication: {#basic-authentication}

Basic authentication is a simple authentication scheme built into the HTTP protocol. In Basic Authentication, the client sends an encoded username and password for authentication. Since username and password sent can be easily deciphered, there is an inherent security vulnerability when using Basic authentication. With basic authentication, every API call is an opportunity for credential theft, which is not ideal. Hence not it is not recommended.

![Rest API Basic Authentication](/blog/assets/2023/rest-api-basic-authentication.webp)

**Authentication methods for SSO Enabled Jira Server:**

If the application is federated using SSO protocols such as SAML/OAuth/OIDC, the user generally does not know his/her application credentials. The user only knows the credentials of the Identity Provider. Hence basic authentication in such cases does not work. In this case, you can use the methods below.

### API Key Authentication {#api-key-authentication}

Use API Keys as an alternative to basic authentication for protection is to secure REST APIs from unauthenticated users. API Key authentication generates a random authentication key for you. Using this key, you can authenticate the REST API by sending it in the authentication request instead of a password. For more security, you can revoke & generate API keys.

From a usability point of view, there are some pros to using API Keys.  One of the clear advantages is its inherent simplicity as well as security. A single identifier is simple, and for some use cases, the best solution since they work better as unique app identifiers. We provide support for API key Authentication where you can additionally control which users can call the secure REST APIs.

![Rest API API Key Authentication](/blog/assets/2023/rest-api-api-key-authentication.webp)

### OAuth 2.0 Authentication {#oauth-2.0-authentication}

This method allows you to authenticate the secure REST APIs of your application using any OAuth/OIDC providers. A client calling a secure REST API can fetch an access token from the OAuth/OIDC provider and use this access token to authenticate an API call.

It is fundamentally a much more secure and more powerful method than the other approaches, mainly because it allows the establishment of scopes that can restrict or provide access to different parts of the API service. It is the best solution for those who have external OAuth2.0 providers. As an added advantage, the token gets revoked after some time, making it much harder to be re-used by attackers.
