Hello @SysAdmin ,
We are currently testing the API and are encountering issues when attempting to use the /transmit endpoint APIs:
• transmit/self-health-check
• transmit/lookup/{IRN}
• transmit/lookup/tin/{TIN}
For all of the above endpoints, we consistently receive the following response:
{
"code": 403,
"data": null,
"message": "error has occurred",
"error": {
"id": "54f2fb2f-b6b7-4e13-bdc8-fcb9ac9ad226",
"handler": "entity_actions",
"public_message": "access denied. user does not have access to this resource"
}
}
Additionally, when calling the /invoice/transmit/{IRN} endpoint, the response is:
{
"code": 404,
"data": null,
"message": "no route found for this path. kindly check your request and try again"
}
For context, our Access Point is currently set to “MBS Default” (screenshot attached).


We also followed the steps under “Webhook Configuration and Notification Mechanism”, but we are unable to locate the “Developer section” referenced in the documentation.
Could you please advise on how to properly enable and access the /transmit endpoints, and clarify where the Developer section can be found?
Thank you.
