Hello veerabhadra reddy kovvuri,
From this documentation, Account admins can change a users status to deactivate the user using the Account Users API.
So to activate the user, you can udpate "value": "True" in the below JSON.
{
"schemas": [ "urn:ietf:params:scim:api:messages:2.0:PatchOp" ],
"Operations": [
{
"op": "replace",
"path": "active",
"value": [
{
"value": "false"
}
]
}
]
}
I hope this helps.
