Hi All,

I have created a Codeunit to modify data in Business Central from a third-party application via API integration. The Codeunit follows these steps:

Validate if the Sales Order No. is blank.
Check the Sales Order status; if the status is open, the Sales Order is allowed to be edited in the third-party application.
Delete staging data in the Instrument Sales Header and Instrument Sales Line tables based on the Sales Order No.
After deleting existing data, re-enter the data based on the JSON object.
Once the staging tables are updated, modify data in the Sales Header and Sales Line tables based on the Sales Order No.
After updating the Sales Header and Sales Line tables, automatically send the Sales Order for approval.

The Codeunit is working, but the API response time is currently too high—it takes about 5.25 seconds. After some optimizations, the response time has been reduced to 4.34 seconds.

I want the response to be in milliseconds, ideally less than 1 second. Please check the attached file of AL code and advise.

use an async API pattern for “sub-second” For true <1s: accept the payload, enqueue work, return 202 Accepted, and process in a background session. That’s the standard web API guidance—and BC supports background sessions

Hi,

To optimize your Codeunit for API integration in Business Central and reduce response time, here are few strategies and official Microsoft resources:
Official Microsoft Learn Links

Performance for Developers [2]

Web Service Performance [1]

OData/API Client Performance [3]

API Limits and Throttling [4]

Optimization Tips

Avoid temp tables for large datasets; they slow down performance.

Use API pages or queries instead of UI pages for web service endpoints.

Batch operations using $batch to reduce multiple calls.

Limit data using $filter, $top, and $select to reduce payload.

Avoid parallel inserts for child records under the same parent.

Use unbound actions for Codeunit procedures exposed via OData.

Split long-running requests and implement retry logic for throttling.

Mark the Boolean true “Does this answer your Question” if this was Helpful.
