How to Add a Groups to host Using the awx API?.

I have a groups( example- group_myproduct) that contains the common variables, I want to add the groups, group_myproduct to a host . How can I achieve this ?

I resolved it, I used the API
/api/v2/groups/{id}/hosts/

Details:
Step -1
http://localhost/api/v2/groups/
{
“name”: “testGroup”,
“description”: “”,
“inventory”: inventory_id,
“variables”: "group_var1: 9 "
}

Step -2

Get the group_id from the above API, Use the below api

http://localhost/api/v2/groups/{group_id}/hosts/

{
“name”: “host1”,
“description”: “”,
“enabled”: true,
“instance_id”: “”,
“variables”: “locahost_var1: 10”,
“inventory”: inventory_id
}

Note that inventory_id should be same for both API
