External APIs

Overview

External APIs APIs (application programming interfaces) are a set of protocols and definitions developers use to build and integrate application software. APIs act as the connective tissue between products and services. enable Creators Also known as Unqork Users, or Designer Users; is anyone who is inside the Unqork platform. to build versatile Centauri (v1.0) The Centauri (v 1.0.0) runtime is the first-generation foundation of the Unqork Designer Platform. Centauri provides Creators a codeless experience for developing applications. and Vega (v2.0) The Vega (v 2.0.0) runtime is the next-generation engine of the UDesigner platform. Vega uses cutting-edge technologies to improve the Creator and end-user experience. applications connecting to thousands of other services. For example, if you need to add a map feature to your application, you might use a Google Maps API. Doing so lets you avoid having to build the map yourself.

About External APIs

Unqork lets Creators integrate external API services into environments. For example, connecting to a CRM (customer relationship management) system, or integrating with a Salesforce instance and DocuSign account.

Making an external API call requires a little extra work compared to an internal API call. First, set up the external service in Services Administration. Then, configure the API with a Plug-In component to make the call.

Setting Up an External Service

To make an external API call, the first step is to set up the service in your Unqork environment. To set up that integration, you need four pieces of information:

Setting	Description
Service Title	This title displays in the External Services drop-down in the Plug-In component. Typically, you use the name of the application or service.
Service Name	The Service Name is permanent. As a best practice, keep Service Names simple and avoid spaces. For example, you might use googlemaps when setting up a Google Maps integration.
Service Protocol + Host	This refers to the URI URI (Uniform Resource Identifier) identifies a resource by name, location, or both. for all API calls made with this service. The URI serves as a locator, telling the API where to direct the call. If any part of the URI is consistent for every call, enter that part here. You can always add to the URI when configuring a specific API call.
Type of Authentication	This is the method of authentication the service or application uses. The service provider determines which method to use. If you're unsure of the authentication type, refer to the API service's documentation.

These are not the only settings on the page, but they’re the minimum required for an external API call. In rare cases, Creators might need to specify certain Request Headers for all calls made using the API. Or, you might need to include certain items in each request body. For more details on each setting, visit the Services Administration article.

How to Make an External API Call

For this example, set up a SendGrid API call to send emails automatically. In Unqork, you can trigger an API call to SendGrid based on end-user End-users, also known as Express Users, are the individuals accessing an application through Express View. In most cases, end-users are the customers using the product. interaction. When an end-user clicks a button, it triggers an API call to SendGrid. Then, SendGrid sends the email.

When configuring API calls, it's best practice to use a Proxy module. Because this example focuses on configuring the API call, you won't create a Proxy module. To learn more about setting up Proxy modules, see our How to: Add a Proxy Module to a Remote Execute article.×

Preconfiguration

Click + Add a Service. The Create New Service modal displays.

4.

In the Service Title* and Service Name* fields, enter SendGrid.

5.

Click Next.

6.

In the Share To field, specify if the service is shared with the Environment, or a specific Workspace.
