Hello Traders, Developers & Partners,
With the upcoming regulatory changes for APIs coming into effect from 1st April 2026, we know that many of you are actively preparing your systems, whether it is around static IP setup, rate limits, or handling market orders on API. We have posted in detail here.
To help you test everything before markets resume on April 1st 2026, we are hosting a live, hands-on online session designed specifically for API traders, developers, and partners.
This session is scheduled for Tuesday, 31st March from 12:00 PM to 2:00 PM, and will be conducted live with the Dhan team over Zoom. Register for it here

This is not a mock trading session from exchanges, nor a live market environment, instead, it is a dedicated session where you can connect with us, test your setup in real-time, and ensure everything is working as expected before 1st April.
During this session, you will be able to run your systems, validate your configurations, and check whether your APIs are fully aligned with the new requirements. At the same time, our team will be available live to walk you through the changes, help you debug issues, and answer any questions you may have.
We highly recommend using this session to verify a few critical things :
- Your IP is correctly whitelisted with DhanHQ,
- Your system is working within the updated rate limits
- Your market orders are handling new MPP validations.
For those who prefer not to manage static IPs, we have a surprise planned for you in the session. There will be an exclusive sneak-peak of the new infra layer, that is extremely useful for every coder-trader.
Since tomorrow is a trading holiday, this becomes the ideal opportunity to test your systems without market pressure, and make any necessary adjustments before the next trading day.
This is your chance to ensure that your trading systems continue to run smoothly, remain compliant, and are fully ready for the new setup.
We look forward to having you join us and build through this transition together.
