Prerequisites for Connecting SQL Databases to Adalo

Before linking your SQL database to Adalo, there are a few key requirements to check off. These steps ensure a smooth integration between your app and database.

First, you must have an Adalo Professional, Team, or Business plan. The External Collections feature, which is necessary for connecting SQL databases, isn't available on the free plan. Professional plans start at $36/month with unlimited usage and no record caps. This pricing compares favorably to alternatives like Bubble (starting at $59/month with usage-based Workload Unit charges and record limits) or FlutterFlow ($70/month per user, plus separate database costs).

Next, you'll need a properly configured SQL database. This guide highlights Microsoft SQL Server, but the process is similar for Azure SQL Database, MySQL, and PostgreSQL. Ensure your database has at least one fully populated record—Adalo might not recognize columns that are completely empty during the setup process.

A crucial point to note is that your SQL table's primary keys must be numeric. Adalo's External Collections feature doesn't support text-based IDs, UUIDs, or special characters. If your database uses non-numeric keys, you'll need to update your schema before proceeding.

Setting Up Your SQL Database

To enable remote access for API communication, configure your database appropriately. For cloud-hosted options like Azure SQL, this involves whitelisting the API service's IP addresses in your firewall settings. If you're using an on-premises SQL Server, make sure remote connections are enabled in the server's configuration.

It's also a good idea to create a dedicated database user specifically for the Adalo connection. This user should have SELECT, INSERT, UPDATE, and DELETE permissions on the tables you plan to link. Stick to granting only the permissions that are absolutely necessary.

Finalize your table structure before connecting to Adalo. Any changes, such as adding new columns after the connection is established, will require you to re-run the connection test and remap the properties in Adalo.

Understanding Adalo's Data Integration Features

Adalo uses a feature called External Collections to connect to external SQL databases. While Adalo's built-in database works well for many apps, External Collections allow you to leverage existing SQL infrastructure and scale to enterprise-level datasets. With the Adalo 3.0 infrastructure update, paid plans now have no record limit cap—your app can handle millions of records without hitting artificial ceilings.

This is a significant advantage over platforms like Bubble, where Workload Units create unpredictable usage charges, or Glide, which restricts data record rows and charges for overages. With Adalo, your SQL integration scales without surprise costs.

Instead of connecting directly to your database through drivers, Adalo communicates via REST APIs. This means you'll need middleware to generate those APIs—this is where DreamFactory comes into play. Any changes made in your SQL database will reflect in your app, and vice versa, ensuring a seamless two-way sync.

Introduction to DreamFactory for API Creation

DreamFactory is a platform that automatically generates REST APIs from your SQL database. It supports over 20 databases, including MS SQL Server, PostgreSQL, MySQL, Oracle, and Snowflake. With DreamFactory, you get auto-generated REST APIs and OpenAPI documentation for secure CRUD operations.

This documentation is critical for Adalo integration, as it defines the endpoints and data structures your app will use. DreamFactory also manages authentication and authorization through methods like API keys, OAuth, JWT, and Role-Based Access Control (RBAC).

For Adalo Blue users, DreamFactory offers deep integration with older systems, even those lacking modern APIs. This is particularly helpful for enterprise teams creating internal apps that need to connect to legacy ERP systems or proprietary databases. To ensure secure communication between Adalo and DreamFactory, have your Adalo API key or OAuth2 credentials ready.

How to Integrate SQL Databases with Adalo

Once you've got everything set up, integrating your SQL database with Adalo using DreamFactory's REST APIs is straightforward. By leveraging Adalo's External Collections, you can sync your SQL data in real time. Here's how to do it in three steps.

Step 1: Generate REST APIs with DreamFactory

Start by logging into your DreamFactory admin interface. Head to the Services section, click Create, and select your database type from the Database menu.

Fill in the required configuration details:

Credential Type	Description	Example
Service Name	Unique identifier for the API URL	`inventory_api`
Host	Database server address	`sql.mycompany.com`
Port	Default port for SQL Server	`1433`
Database Name	Name of the database you're connecting	`inventory_db`
Username	Your database login name	`db_user`

Next, set up a Role with proper access permissions and generate an API Key to ensure secure integration. Don't forget to enable SSL encryption in DreamFactory's advanced settings—this step is crucial for keeping your data secure during transmission.

Before moving on, test your API endpoints using DreamFactory's API Docs. This will help confirm that your JSON responses are structured correctly and save you troubleshooting time later. As Kevin McGahey, Solutions Engineer at DreamFactory, puts it:

"DreamFactory simplifies API creation by automating the process, reducing development time by up to 90%."

With your APIs ready, you're all set to configure the endpoints in Adalo.

Step 2: Configure API Endpoints in Adalo

In Adalo, go to the Database tab, choose External Collections, and click Add Collection. Enter the API Base URL from DreamFactory, which will look something like this:

https://instance.dreamfactory.com/api/v2/{service_name}/_table/{table_name}

To authenticate, add a Header Parameter. Set the header name to X-DreamFactory-API-Key and use your DreamFactory API Key as the value.

For the Get All endpoint, set the Results Key to resource.

Adalo supports five standard endpoint actions: Get All Records, Get One Record, Create a Record, Update a Record, and Delete a Record. While Adalo provides default settings, you might need to tweak them. For example, some setups require changing the HTTP method from PUT to PATCH for updates. After configuring your endpoints, run a test connection. If everything checks out, Adalo will automatically detect the data properties from your API response.

Step 3: Map SQL Data to Adalo Components

Once your External Collection is connected, you can map SQL data to Adalo's visual components. For instance, to display multiple records, add a List component to your screen and set its "What is this a list of?" property to your External Collection.

To bind database fields to UI components, use Magic Text. Click the Magic Text icon when configuring a text element, and you'll see all available fields from your SQL table—like first_name, last_name, or product_price. Select the field you want to display.

For interactive features, such as updating or deleting records, assign custom actions to buttons or forms. These actions will trigger the corresponding API endpoints you configured earlier, enabling two-way data sync. This setup allows teams to manage data either through the app's interface or directly in the database.

Adalo's responsive design ensures that your app works smoothly across web, iOS, and Android devices—all from a single build. With over 3 million apps created on the platform and an uptime exceeding 99% over the past year, Adalo is reliable for handling production workloads. The visual builder has been described as "easy as PowerPoint," making SQL integrations accessible even to non-technical team members.

Authentication and Permissions with Adalo Blue

When it comes to enterprise apps, security isn't just a feature—it's a necessity. Adalo Blue steps up to the challenge with authentication and permission controls built for demanding environments. One standout feature is its support for SAML Single Sign-On (SSO), allowing teams to use their existing corporate credentials to access apps connected to sensitive SQL data. This eliminates the hassle of managing separate login systems.

Adalo takes a two-pronged approach to security. Authentication is handled through either SSO or Adalo's built-in system, while SQL database connections are protected independently using Authorization Headers with Bearer or Personal Access Tokens. This separation ensures that even if unauthorized access occurs at the app level, database records remain secure. Together, these layers provide a solid foundation for managing tokens and users effectively.

To ensure users only see the data they're supposed to, Adalo leverages the "Logged-in User" property to filter SQL records by user ID. This creates row-level security, restricting access to authorized data. For an extra layer of protection, you can build filtered SQL views that accept user ID parameters and connect them as distinct External Collections in Adalo. By shifting security logic to the database level, you reduce reliance on the app layer for data protection.

Adalo Blue also offers role-based access control (RBAC) and two-factor authentication (2FA) to manage app editing permissions and database configuration access. The platform is SOC 2 Type II certified and ensures data security with TLS/SSL encryption for data in transit and AES-256 encryption for data at rest. With over 20 million data requests processed daily, these measures are designed to handle real-world production workloads.

For token management, Adalo recommends creating separate Personal Access Tokens for development, staging, and production environments. Use only the required scopes for each token, rotate them quarterly, or immediately if team members leave. To avoid security risks, never embed tokens in client-side code or public repositories. Instead, store them securely in Adalo's configuration settings.

Testing and Troubleshooting SQL Integrations in Adalo

Once you've mapped your SQL data to Adalo components, it's critical to test everything thoroughly to ensure the integration works seamlessly.

Start by pressing the Test button after setting up your SQL connection. If the setup is correct, you'll see a green success message along with an example response. If there's an error message instead, it means something needs fixing. This test serves as the final check to confirm that your earlier configurations—such as those done via DreamFactory and Adalo's API setup—are working as intended.

Adalo's X-Ray feature can help identify performance issues before they affect users. This AI-powered diagnostic tool highlights potential bottlenecks in your data connections, helping you optimize queries and ensure smooth performance as your user base grows.

Common Errors and Fixes

One frequent issue is the 401 Unauthorized error, which often stems from incorrectly formatted Authorization Headers. For Bearer tokens, the header should follow this format: Authorization: Bearer your_token_here. To avoid invisible character issues, paste your API token into a plain text editor first, then copy it into Adalo. Also, double-check that all data fields are correctly detected to prevent any "missing property" errors.

If you encounter missing data fields, it's likely because some SQL columns are empty. Adalo requires data in every column (even placeholder data) to properly detect all fields. Adding a dummy record with values in every column can resolve this.

When testing updates, be cautious about your HTTP method. Using PUT instead of PATCH can result in data loss, as PUT overwrites entire records. PATCH, on the other hand, updates only the specified fields. Always verify you're using PATCH to avoid unintended data erasure.

Troubleshooting Guide

Here's a quick reference table to help you diagnose and fix common errors:

Error Code / Issue	Likely Cause	Recommended Resolution
401 Unauthorized	Missing "Bearer " prefix or incorrect token scopes	Verify header format: `Authorization: Bearer [token]`
404 Not Found	Excess query parameters in Base URL	Remove everything after the `?` in the Base URL
Data Erased on Update	Endpoint set to `PUT` instead of `PATCH`	Change the Update Record method to `PATCH`
Missing Fields	Columns in source database are empty	Add a dummy record with data in all columns and re-test
Only 100 Records Show	API fetch limit reached	Configure pagination or use filtered views at the source
ID Errors	ID is a string or UUID	Ensure the ID field is in numeric format

How Adalo Compares for SQL Database Apps

When choosing a platform for SQL-connected apps, understanding the alternatives helps clarify why Adalo's approach stands out.

Bubble offers extensive customization but comes with trade-offs. Its mobile solution wraps the web app rather than compiling to native code, which can introduce performance challenges at scale. Bubble's Workload Unit pricing creates unpredictable costs—calculations are complex and charges can spike unexpectedly. Claims of supporting millions of MAU often require hiring experts to optimize performance, adding significant expense. Starting at $59/month with usage limits, Bubble's total cost of ownership frequently exceeds initial estimates.

FlutterFlow targets technical users with a low-code approach. However, users must source, set up, and pay for their own database separately—a significant learning curve, especially when optimizing for scale. Suboptimal database setup creates scalability problems that spawn an ecosystem of paid consultants. At $70/month per user (before database costs), FlutterFlow's total investment climbs quickly for teams.

Glide excels at spreadsheet-based apps but restricts users to set templates, limiting creative freedom. While fast to build with, the resulting apps feel generic. Pricing starts at $60/month for custom domains but includes limits on app updates and data rows that trigger additional charges. Glide doesn't support App Store or Play Store publishing.

Softr focuses on web apps from spreadsheets, starting at $167/month for Progressive Web Apps—still restricted by records per app and datasource. Like Glide, Softr doesn't support native iOS or Android app creation.

Adalo's $36/month starting price includes unlimited usage, no record caps on paid plans, and direct publishing to both app stores. The single-codebase approach means one build updates web, iOS, and Android simultaneously—a workflow advantage competitors don't match.

Conclusion

Connect your SQL database with Adalo to create and roll out fully functional apps in just days. Instead of months of custom development, you can quickly launch polished iOS, Android, and web applications from a single codebase.

This integration can cut costs by up to 65% and save teams around 15 hours each week by automating data synchronization. It transforms how efficiently data is turned into user-facing applications.

Scalability is another major benefit.
