Then, add the following snippets to your code:
React Node Python
Copy import { init , useQuery } from "@airstack/airstack-react" ;
init ( "YOUR_AIRSTACK_API_KEY" );
const query = "YOUR_QUERY" ; // Replace with GraphQL Query
const Component = () => {
const { data , loading , error } = useQuery (query);
if (loading) {
return < p >Loading...</ p >;
}
if (error) {
return < p >Error: { error .message}</ p >;
}
};
Copy import { init , fetchQuery } from "@airstack/airstack-react" ;
init ( "YOUR_AIRSTACK_API_KEY" );
const query = "YOUR_QUERY" ; // Replace with GraphQL Query
const { data , error } = fetchQuery (query);
console .log ( "data:" , data);
console .log ( "error:" , error);
Copy import asyncio
from airstack . execute_query import AirstackClient
api_client = AirstackClient (api_key = "YOUR_AIRSTACK_API_KEY" )
query = "YOUR_QUERY" # Replace with GraphQL Query
async def main ():
execute_query_client = api_client . create_execute_query_object (
query = query)
query_response = await execute_query_client . execute_query ()
print (query_response.data)
asyncio . run ( main ())
