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

40 Replies to “Read table change records by using platform APIs”
Does anyone have experience using platform APIs to read table change records for audit purposes?
Yes, I’ve used the Dataverse change tracking API for that. It’s quite efficient.
Agreed, Dataverse API is robust for such tasks. Just make sure your tables are enabled for change tracking.
I’ve followed the steps, but I’m running into a 401 unauthorized error. Any ideas?
Also ensure that your application’s service principal has the necessary role assignments.
Check your API permissions and the token you’re using. A 401 usually means authentication issues.
The API latency seems high for my use case. Are there any optimization tips?
Look at your query design—filtering and batching can improve performance significantly.
How does the performance of change tracking API hold up under heavy usage?
It performs well up to a point. For extremely heavy usage, consider using additional Azure services like Event Hubs.
Is it necessary to enable change tracking on every table I want to audit?
Yes, change tracking must be enabled on each table individually.
The provided code sample doesn’t seem to work. Any idea why?
Can you specify the error you’re encountering? It might help narrow down the issue.
How do we secure the data fetched using these APIs?
Use Azure AD for authentication and ensure encrypted connections to maintain data security and integrity.
I’ve been tasked with implementing this next week. Any pitfalls I should be aware of?
Watch out for high data volumes—plan your storage and processing capabilities in advance.
Can we retrieve historical data using the platform APIs or just recent changes?
The platform APIs are designed more for recent changes. For historical data, you might need data archival mechanisms.
This feature is brilliant, but the documentation could be clearer.
I agree, supplemental community resources can often fill those gaps.
This blog post saved me a ton of time. Thank you!
This blog post pointed me in the right direction. Much appreciated!
Do platform APIs support batching when reading change records?
Yes, batching is supported to improve performance and reduce the number of API calls.
Is there a way to track deleted records using the API?
Yes, you can track deletions if change tracking is enabled, but you’ll need to handle the logic for processing ‘delete’ change types.
Could anyone guide me on integrating these APIs with logic apps?
Logic Apps have built-in connectors for Dataverse, making integration straightforward.
What are the licensing implications of using these APIs?
You’re right to consider that. Licensing costs can add up if you’re accessing large volumes of data.
Can anyone share a sample code snippet for reading table change records?
I can help with that. Are you working with C# or JavaScript?
Can you provide more details on the performance benchmarks of these APIs?
Microsoft documentation provides some benchmarks, but real-world performance can vary. Testing in your environment is crucial.
Thank you for this helpful blog post!
Just wanted to say thanks for this post.
I tried using this approach but faced limitations in data types. Anyone else?
Certain complex data types can be tricky. Custom serializers can sometimes help.
