Not able to create contacts

[GregS486]

Hi Team,
I am working on to integrate with v3 API with my java Application. I am able to create list ,get contacts, get lists from constant contact but once I am trying to create the contacts in the list or separate contacts it is giving me this error.
I tried with same account from API Reference it is working fine.
These are my authorization scopes:
contact_data+campaign_data+account_read+account_write+offline_access+openid
{"message":"Forbidden"}
This is my request payload:
{
"email_address": "j***@m***.com",
"list_memberships": [
"adc1d9e6-da5a-11ee-adfe-fa163e57b7cb"
]
}
