Zabbix 6.0 API HTTP error 412 ~ Precondition failed

[Cejay]

We are using Zabbix 6.0 And are trying to do an API Call, and get the following error when using the api url

https://ourzabbixserver/zabbix/api_jsonrpc.php

We have checked the API user permissions and the post request header and it all checks out okay.

We are using PHP, and Zabbix 6.0.

I did do a search and didn't come across anything solid, apart from the API User permissions setting which we checked.

Any help would be appreciated

See above picture showing the error.

And can you show the request that you are trying? With all the relevant headers.

If you are doing the call in a software, can you repeat the same error with a simple curl command?

I've talked to our developer and this is what they are seeing. Please note I have removed some information that we do not want to share

Umm, ok, you are using some Windows command, not the stardard curl, and you are not giving any command to the API, right. You do realize that you are not yet providing any meaningful input for anyone else to help you with this?
