How to test ServiceNow Rest API for attachment using POSTMAN.

[Ajay95]

Hi,

I need to test ServiceNow Rest API for attachment using POSTMAN as client instances are accessible through VPN only. As their instances are not in public domain.

When I tried to sent request using Basic Auth it is going timeout.

Note : Instance has SSO enabled.

Below REST API I am using to fetch the attachment :

Versioned URL:  <SERVICE-NOW>/ api /now/v1/attachment/ {sys_id} /file

I am using Postman Desktop application even though it is giving timeout.

Can anyone help me with this issue?

are you using correct basic auth credentials?

since you said instance is in VPN i.e. firewall then I believe you cannot test it via postman
