Viewing ApprovalMax Data in RAD Studio Data Explorer
Embarcadero RAD Studio provides a development environment for Delphi and C++Builder applications. With the CData ODBC Driver for ApprovalMax, you gain access to live ApprovalMax data within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to both retrieve ApprovalMax data. This article will walk through connecting to ApprovalMax using the Data Explorer.
Configure a Connection to ApprovalMax
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.
Start by setting the Profile connection property to the location of the ApprovalMax Profile on disk (e.g. C:\profiles\ApprovalMax.apip). Next, set the ProfileSettings connection property to the connection string for ApprovalMax (see below).
ApprovalMax API Profile Settings
To authenticate to ApprovalMax and connect to your own data or to allow other users to connect to their data, the ApprovalMax Public API requires the OAuth 2.0 authorization code flow.
First, you will need to register an OAuth application with ApprovalMax. Sign in to the ApprovalMax Developer Portal (https://developer.approvalmax.com/applications) and create a new application. Your OAuth application will be assigned a Client ID and a Client Secret, and you must register at least one Redirect URI (Callback URL).
A Premium ApprovalMax subscription (or active trial) is required to use the Public API.
After setting the following connection properties, you are ready to connect:
- AuthScheme: Set this to OAuth.
- InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to manage the process to obtain the OAuthAccessToken.
- OAuthClientId: Set this to the Client ID that is shown in your application settings on the ApprovalMax Developer Portal.
- OAuthClientSecret: Set this to the Client Secret that is shown in your application settings on the ApprovalMax Developer Portal.
- CallbackURL: Set this to the Redirect URI that is registered in your application settings.
- Scope: (Optional) Override the default OAuth scopes. The default value openid offline_access https://www.approvalmax.com/scopes/public_api/read grants read-only access to all tables in this profile and enables refresh tokens. Use the principle of least privilege when narrowing this scope.
The OAuth Authorization URL is https://identity.approvalmax.com/connect/authorize and the Token URL is https://identity.approvalmax.com/connect/token. Both authorization_code and refresh_token grant types are supported.
Connecting to ApprovalMax Data Using Data Explorer
You can create a simple application for displaying ApprovalMax data by utilizing the CData FireDAC Components for ApprovalMax and a new VCL Forms Application:
- Open the Data Explorer in RAD Studio and expand FireDAC.
- Right-click the ODBC Data Source node in the Data Explorer.
- Click Add New Connection.

- Enter a name for the connection.
- In the FireDAC Connection Editor that appears, set the DataSource property to the name of the ODBC DSN for ApprovalMax.

- Back in the Data Explorer, expand the views for the connection.
Create a new VCL Forms application and drag a view (for example: UserProfiles) onto the form.

- Select the UserProfilesView object on the form and set the Active property to true.
Right-click on the object, bind visually, and link everything (*) to a new control (TStringGrid).

Arrange the TStringGrid on the form and run the application to see the UserProfiles data.
