Yealink RPS API error

[kov]

I'm trying to get started using Yealink RPS for auto provisioning, and am making som test api requests, following the documentation found here:https://support.yealink.com/forward2filesystem/attachment/upload/attachment/2021-2-3/5/49bdb7cd-55de-40c4-a2c6-c88f6e3598f9/Yealink+Json+API+for+RPS+Management+Platform+V3.6.0.30.pdf



I've testet the POST request for listing servers, and the CheckMac api, and both return the same internal server error response, which has a body that indicates the endpoint was not found.

{

"ret": -1,

"data": null,

"error": {

"msg": "service.common.not.found",

"errorCode": 404,

"fieldErrors": []

}

}





For the checkmac request the full uri i'm requesting is

https://api-dm.yealink.com:8443/api/open...1565123123


I've added the Headers mentioned in the pdf, and created the signature, but i suspect that the backend doesn't get to validating those, when i get a 404 response.



Am i missing something obvious about the URL's for the Yealink RPS API ?
