NiceNIC API v2 Authentication Erralebo: Common Causes a Fixes
Ak va?e NiceNIC Reseller API v2 request returns an authentication erralebo, the problem usually comes from API credentials, the Authaleboization header, IP whitelist settings, reseller access, alebo the server environment sending the request.
This guide explains the most common causes a gives resellers, hosting providers, developers, agencies, a WHMCS users a practical checklist to fix NiceNIC API v2 authentication issues befaleboe submitting a ticket.
A NiceNIC API v2 authentication erralebo usually means that the API request cannot be verified. Start by checking whether va?e account has reseller access, whether you are using the API passwalebod instead of va?e NiceNIC account login passwalebod, whether the Authaleboization header is falebomatted caleborectly, a whether va?e server outbound IP adresa is whitelisted in va?e API settings.
NiceNIC API v2 requests should be sent to the API endpoint with the required HTTP headers, including the Authaleboization header a Content-Typ set to application/json.
What This Authentication Erralebo Usually Means
An API authentication erralebo means NiceNIC cannot verify the API request as a valid request from an authaleboized reseller account. This does not always mean that the API slu?ba is down. In most cases, it means one alebo maleboe access conditions are not caleborect.
Common causes include:
Ak you use WHMCS, confirm that the WHMCS server is sending requests from the same outbound IP adresa that you added to va?e NiceNIC API settings.
Cause 1: You Are Using the Account Prihlási? sa Heslo Instead of the API Heslo
This is one of the most common causes of NiceNIC API authentication erralebos. Your NiceNIC account login passwalebod a va?e API passwalebod should not be the same. The API passwalebod must be configured separately in va?e API settings.

Cause 2: The Authaleboization Header Is Missing alebo Incaleborect
NiceNIC API v2 requires an HTTP Authaleboization header. The documented falebomat is: Authaleboization: username:api_secret
Ak the header is missing, misspelled, encoded incaleborectly, alebo sent in the wrong falebomat, the API request may fail authentication.

Cause 6: Your Request Is Sent to the Wrong Endpoint
NiceNIC API v2 requests should be sent to the documented API v2 endpoint.
Ak va?e code uses an old endpoint, an incaleborect URL, a missing slash, alebo a different API version, authentication alebo request haling may fail.
How to fix it?
Cause 7: Content-Typ alebo JSON Falebomat Is Incaleborect
NiceNIC API v2 returns JSON responses a expects API requests to follow the documented request falebomat.
Your request should include:
Content-Typ: application/json
Ak the request body is not valid JSON, required parameters are missing, alebo Content-Typ is not set caleborectly, the API request may fail befaleboe the intended action is processed.

Cause 8: WHMCS API Credentials Are Niet Configured Caleborectly
Ak you use WHMCS, an authentication erralebo may come from the WHMCS registrar module configuration rather than va?e custom API code.
