# HTTPXAsyncTransport

This transport uses the httpx library and allows you to send GraphQL queries using the HTTP protocol.

Reference: `gql.transport.httpx.HTTPXAsyncTransport`

Note

GraphQL subscriptions are not supported on the HTTP transport. For subscriptions you should use the websockets transport.

    import asyncio

    from gql import Client, gql
    from gql.transport.httpx import HTTPXAsyncTransport

    async def main():

        transport = HTTPXAsyncTransport(url="https://countries.trevorblades.com/graphql")

        # Using `async with` on the client will start a connection on the transport
        # and provide a `session` variable to execute queries on this connection
        async with Client(
            transport=transport,
            fetch_schema_from_transport=True,
        ) as session:

            # Execute single query
            query = gql(
                """
                query getContinents {
                  continents {
                    code
                    name
                  }
                }
            """
            )

            result = await session.execute(query)
            print(result)

    asyncio.run(main())

## Authentication

There are multiple ways to authenticate depending on the server configuration.

1. Using HTTP Headers

    transport = HTTPXAsyncTransport(
        url='https://SERVER_URL:SERVER_PORT/graphql',
        headers={'Authorization': 'token'}
    )

2. Using HTTP Cookies

You can manually set the cookies which will be sent with each connection:

    transport = HTTPXAsyncTransport(url=url, cookies={"cookie1": "val1"})
