I would really appreciate if you can help.

Thank you very much, stay healthy.

It is or the server access hash or the user (always admin) / server password

What values dit you provide (Please use dummy data)

params will be filled in whmcs backend. @gunka eris asked for logs, what exactly is your issue? What’s the error message you got? Did you checked the web log for additional informations?

Module
Vesta
User name
admin
Password
••••••••••••••••

Are you just copy&pasting? :smiley:

:slight_smile:
As you said, I choose vesta panel in the whmcs servers section and there I enter the ip username and password, but,
command reports operation failed.

Ok, and in the web server logs? Is the backend port 8083 open, can you reach it for example with curl? We can’t take over the debug work for you :slight_smile:.

In the past, this code I sent to vesta was successful, it was working, after the updates it was working about 8 months ago.

I want to automatically create accounts in whmcs, delete, freeze, etc.

Welcome to the Hestia Control Panel
User name

Previously, the user name and password came together, now the user name comes first. Could it have something to do with it?

Vesta != Hestia, even when the api should be the same. Probaly you’ve a connection issue, but as written: We can’t debug it for you nor provide the needed sysadmin skills.

You mean the installation output or in the whmcs backend?

Normally, if the code we use in vesta whmcs is valid, I wonder if it works now, then there is a problem with my settings :frowning:

the whmcs backend

No idea, the whmcs module is not from us, it’s still vesta base. It could or can work, because the api is still the same.

I am entering as admin while creating a user, I wonder if there may be an authorization restriction.

You could try to validate the api connection manualy to gain more informations: https://docs.hestiacp.com/admin_docs/rest_api.html

Add the following code to v-add-user and it will work fine
