Connect to JSON Services Using the Script Function in Claris FileMaker Pro

Claris FileMaker is a low-code database application development tool that enables users to create custom apps for managing and organizing data. It combines a powerful relational database engine with an intuitive interface, allowing both technical and non-technical users to design and deploy applications across desktop, web, and mobile platforms.

In this article, we'll explore how to use the CData ODBC Driver for JSON and FileMaker scripting to connect to JSON services.

Create an ODBC Data Source for JSON

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

See the Getting Started chapter in the data provider documentation to authenticate to your data source: The data provider models JSON APIs as bidirectional database tables and JSON files as read-only views (local files, files stored on popular cloud services, and FTP servers). The major authentication schemes are supported, including HTTP Basic, Digest, NTLM, OAuth, and FTP. See the Getting Started chapter in the data provider documentation for authentication guides.

After setting the URI and providing any authentication values, set DataModel to more closely match the data representation to the structure of your data.

The DataModel property is the controlling property over how your data is represented into tables and toggles the following basic configurations.

• Document (default): Model a top-level, document view of your JSON data. The data provider returns nested elements as aggregates of data.
• FlattenedDocuments: Implicitly join nested documents and their parents into a single table.
• Relational: Return individual, related tables from hierarchical data. The tables contain a primary key and a foreign key that links to the parent document.

See the Modeling JSON Data chapter for more information on configuring the relational representation. You will also find the sample data used in the following examples. The data includes entries for people, the cars they own, and various maintenance services performed on those cars.

When you configure the DSN, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

Connect and Sync JSON services with FileMaker Using Scripts

In this section, we walk through the steps to connect live JSON services to FileMaker using the CData ODBC Driver for JSON and the Script function. During the initial import, FileMaker brings in all data from the external data source. From the second import onward, it updates only the data that has changed in the external source (a differential update). You can also replace the data in the current record order and schedule these differential updates for automated syncing.

You can download and install the latest version of FileMaker Pro for your Mac/Windows/Linux systems from this link.

Connect and sync JSON services with FileMaker using scripts

Scripting in FileMaker automates complex tasks and workflows by running a sequence of actions with a single command. By using scripting to integrate with JSON, you can automatically connect to, import, update, and replace JSON services within your FileMaker applications, streamlining data management and improving efficiency.

First-time importing and adding JSON services using script

In this section, we'll use scripts to import JSON services into FileMaker by following these steps:

1. Open FileMaker Pro. Navigate to Create from the left panel and select Blank > Create.

2. Enter a filename of your choice and click Save.
3. In the Manage Database window, go to the Tables tab and create or rename the table where you want to display the JSON services.

4. In the Fields tab, create and add the fields you want to use in the table.

5. In the Relationships tab, add table relationships if there are multiple tables, then click OK.

6. To reopen and modify the table structure, go to File > Manage > Database.
7. Navigate to Scripts > Script Workspace.

8. Select New Script to open a new script workspace.
9. From the Steps panel on the right, select Records > Import Records > Insert into Script.

10. In the Specify Data Source dropdown, choose ODBC Data.
11. Select CData JSON Sys from the Select ODBC Data Source window, and click Continue. Enter your JSON credentials and click OK.

12. In the Specify ODBC SQL Query dialog, enter the SQL query in the SQL text editor to import the desired JSON services.

13. Alternatively, select Query Builder to open the SQL Query Builder window. Choose the target table from the Tables section and relevant columns from the Columns section. Click Insert into SQL Query after each selection to auto-generate the query. You can also manually edit the query using WHERE and ORDER BY clauses or the designated tabs. Click OK to finalize the query.

14. Click OK.
15. In the Specify import order option, click Specify and enter the JSON credentials.

16. In the Specify Import Order window, define the import order for the target fields you added earlier. Select Add between the source and target fields to insert the JSON services as new records in the table. Click Import.

17. The script now appears in the workspace. Click Run to execute the script and process the import.

18. FileMaker imports the JSON services as a table.

Update or Replace Imported JSON services Using a Script

After importing the JSON services into FileMaker, use scripts to update or replace any changes made in JSON by following this process:

1. Go back to the Script Workspace by following the steps mentioned in the earlier section.
2. Select the existing script, click the settings button, choose Specify under Specify Import Order, and re-enter the JSON credentials to authenticate.

3. In the Specify Import Order window, choose Update between source and target to update the imported JSON services. This updates the target's found set with JSON services values from selected fields when the match fields have the same values. You must define at least one match field in the mapping and select the checkbox Add remaining data as new records. Click Import.

4. Alternatively, choose the Replace option instead of Update, based on your use case. This replaces the selected fields in the target's found set with JSON services in the current record order. Click Import.

5. FileMaker adds the script to the workspace. Click Run to execute the script and process the import query.
6. FileMaker imports the updated or replaced JSON services as a table.
