Check out why the developers love Retool to use as a low-code tool and make an informed decision that leads to surprising results.
The following section will guide you through the detailed use of API data to populate application components in Retool.
Using API Data to Populate Application Components in Retool
Retool offers a robust platform for creating internal tools using data from different APIs. This flexibility empowers developers to build dynamic applications that fetch, display, and manipulate real-time data. Integrating external APIs can enhance Retool applications, making them more responsive and data-driven. This guide covers invoking API endpoints, populating tables with API data, and using features like filtering, pagination, and CRUD operations.
Process of Invoking API Endpoints to Retrieve Data
Invoking API endpoints in Retool involves creating queries that interact with your external APIs. Here’s a step-by-step process:
Create a New Query:
Navigate to your Retool app and click the "+" button to create a new query.
Select the type of API you want to connect to, such as REST or GraphQL.
Configure the API Request:
Enter the API endpoint URL and choose the HTTP method (GET, POST, PUT, DELETE).
Add any required headers, parameters, and body content using the API.
Test the Query:
Run the query to ensure it retrieves the expected data. Adjust the configuration if needed.
Save the Query:
Save the query and give it a descriptive name for easy identification.
Examples of Populating a Table with Data from an API
To populate a table with data from an API in Retool, follow these steps:
Create and Test the Query:
As described above, create a query to fetch data from your API.
Ensure the query returns the data in the expected format, typically an array of objects.
Add a Table Component:
Drag and drop a Table component onto your canvas from the component library.
Bind the Query to the Table:
In the Table component's properties panel, set the data source to the query you created.
For example, if your query is named getUsers, set the data property of the table to {{ getUsers.data }}.
Customize Table Columns:
Configure the table columns to display relevant fields from the API data. You can rename columns, format data, and add sorting or filtering as needed.
Using Filter, Pagination, and CRUD Operations with APIs
Filters and Pagination:
Filters: Add input components like dropdowns or text inputs to capture filter criteria from the user. Bind these inputs to your query parameters to dynamically filter the data.
Pagination: Implement pagination by configuring your query to accept pagination parameters (e.g., page and pageSize). Update the query results based on the user's interaction with pagination controls.
Example of Pagination Setup:
Add Pagination Controls:
Add buttons or a pagination component to navigate between pages.
Bind these controls to variables that represent the current page and page size.
Modify the Query:
Adjust the query to include pagination parameters:javascript
const page = {{ currentPage }};
const pageSize = {{ pageSize }};
return fetch(`/api/users?page=${page}&size=${pageSize}`)
.then(response => response.json());
CRUD Operations:
Create: Use forms and input fields to capture new data entries. Submit the data to the API using a POST request.
Read: As described, fetch and display data in components like tables.
Update: Allow users to edit data in place or through a modal form. Send the updated data to the API using a PUT or PATCH request.
Delete: Add buttons or actions to delete records. When these actions are performed, trigger a DELETE request to the API.
Example of an Update Operation:
Create an Edit Form:
Add input fields and pre-fill them with the data you want to edit using the selected row in the table.
Bind the form inputs to a state variable representing the current item.
Submit the Update:
Add a button to submit the form. Configure the button to trigger a query that sends a PUT request with the updated data.
const updatedData = {
id: {{ currentItem.id }},
name: {{ currentItem.name }},
email: {{ currentItem.email }},
};
return fetch(`/api/users/${updatedData.id}`, {
method: 'PUT',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify(updatedData),
}).then(response => response.json());
Following these steps, you can effectively use API data to populate and interact with components in Retool, creating dynamic and responsive internal tools.
Now, move on to the next step, where you can customize and extend your application in Retool.
Customizing and Extending Your Application in Retool
Retool offers a wide range of customization options to enhance the functionality of your applications. You can integrate utility APIs, customize resource queries, and improve user interactions with pre-built and custom widgets. These options allow you to create dynamic applications that meet your specific needs.
Integrating Utility APIs for Added Functionalities
Integrating utility APIs into your Retool applications can significantly enhance their functionality. By leveraging APIs like ApyHub for utility services, you can add features such as data validation, document generation, and more. Here’s how to integrate an API:
Create a New Resource: Navigate to the Resources tab, select "Create new", and choose "REST API".
Configure the API: Enter the API's base URL and any necessary headers. For example, set the base URL to https://api.apyhub.com and include an authorization header if required.
Test the API: Create a query to test the API connection and ensure it returns the expected data.
Customizing Resource Queries for Specific Use Cases
Customizing resource queries allows you to tailor your application to specific needs. For instance, you can use SQL, JavaScript, or other query languages to interact with your data sources:
Create and Configure Queries: Open the query editor, select the resource, and write your custom query. For example, to fetch user data, you might use:
SELECT * FROM users WHERE status = 'active'
Dynamic Queries: Make your queries dynamic by using variables and inputs. For example, add a dropdown to filter users by role and bind this input to your query.
Enhancing User Interactions with Pre-Built and Custom Widgets
Retool provides a wide array of pre-built widgets like Tables, Charts, Forms, and Buttons, which you can use to enhance user interactions. Additionally, you can create custom components using HTML, CSS, and JavaScript:
Pre-Built Components: Drag and drop components from the library onto your canvas. For instance, a table component can display data, and a button component can trigger actions.
Custom Widgets: To build custom components, use the iFrame Code field in the Inspector to write your HTML, CSS, and JavaScript. For example, you can create a custom input field that updates a query dynamically:
<input type="text" onkeyup="updateQuery(event)" />
<script>
function updateQuery(event) {
window.Retool.modelUpdate({ searchTerm: event.target.value });
}
</script>
Integrating utility APIs, customizing queries, and enhancing user interactions with pre-built and custom widgets can create highly functional and responsive Retool applications. \For more detailed information, visit Retool’s official documentation on advanced app examples and custom components.
