Concepts

Introduction:

Microsoft Power Platform Developer provides a comprehensive set of tools and APIs that enable developers to build powerful solutions for data management and automation. One essential task in developing applications is the ability to read table change records. In this article, we will explore how you can accomplish this using the platform APIs.

Understanding Table Change Records:

Table change records are a fundamental concept in Power Platform development, allowing you to track and retrieve changes made to a table over time. These records are particularly useful when you need to extract specific changes and apply business logic accordingly. Power Platform provides APIs that enable developers to programmatically access these change records and incorporate them into their applications.

Using the Retrieve Table Change Records API:

The Retrieve Table Change Records API allows developers to fetch change records for a specific table. To leverage this API, you need to understand its parameters and the resulting response.

  • Table Name: Specify the name of the table for which you want to retrieve change records. This parameter is mandatory and should be provided in the API call.
  • Start Time: Specify the start time from which you want to retrieve change records. This parameter is optional, allowing you to fetch records from a specific point in time. If not provided, the API will return all records.
  • End Time: Specify the end time until which you want to retrieve change records. This parameter is also optional and determines the range of records to be fetched. Omitting this parameter will retrieve records until the current time.

Response:

The API response will contain an array of change records in JSON format. Each record will include information such as record ID, timestamp, operation type (create, update, or delete), and the changed field values. You can parse and utilize this data in your application logic accordingly.

Example API Call:

To illustrate the API usage, let’s consider an example where we retrieve change records for a table named “Customers” between a specific time frame.

Endpoint:
GET /api/data/v9.2/RetrieveTableChangeRecords

Parameters:

  • table: “Customers”
  • start_time: “2022-01-01T00:00:00Z”
  • end_time: “2022-01-31T23:59:59Z”

The API call above will retrieve all the change records for the “Customers” table within the specified time frame.

Applying Table Change Records in Your Application:

Once you have retrieved the change records, you can apply your business logic based on the information they provide. For example, you can process the “create” records to add new entries, update existing records based on “update” records, or delete records based on “delete” records. By utilizing these change records, you can ensure synchronicity between your application and the underlying data.

Conclusion:

The ability to read table change records is a crucial aspect of developing applications with Microsoft Power Platform Developer. With the Retrieve Table Change Records API, you can easily retrieve and process change records for a specific table. By incorporating this functionality into your application logic, you can build robust solutions that leverage the power of the Power Platform.
