For those of you who are currently activating or configuring the Trade API, we would like to inform you that currently, the OTP (One-Time Password) code for Trade API verification is only available via SMS. Other delivery methods such as WhatsApp cannot be used for this feature due to technical security standards. If you are having trouble receiving the OTP code via SMS, please follow these self-check steps:
Ensure that the mobile number you are currently using is the primary number registered on your Indodax account. The OTP code will not be sent to a relative's number or a different number.
Ensure that the number is active (has sufficient credit) and is within the range of a stable and strong operator signal.
A full SMS inbox often prevents new messages from coming through. Try deleting some old messages from your phone's inbox.
Refresh your network by turning on Airplane Mode for a few seconds, then turning it off again to trigger a signal refresh.
Make sure your phone is not blocking messages from unknown numbers (Spam Filter).
If you have reached the limit and still haven't received the code, please wait 15 minutes for the system to reset before trying again.
If the problem with receiving SMS messages is due to the registered mobile number being expired, lost, or inactive, you are required to change your phone number first. Complete instructions on how to change your phone number can be accessed via the following official link: Guide on How to Change Your Mobile Phone Number
