# Form parameters (HTTP POST)

The OAuth 2.0 client authenticates by sending `client_id` and `client_secret` form parameters in an HTTP POST request:

```bash
$ curl \
--request POST \
--data "client_id=myClient" \
--data "client_secret=mySecret" \
...
```

To use this authentication method for a confidential OAuth 2.0 client, edit the client profile in the Advanced Identity Cloud admin console:

1. Go to Applications > *Name* > Sign On > General Settings > Advanced > Authentication.

2. Set the Token Endpoint Authentication Method to `client_secret_post` and save your work.

Make sure all connections to Advanced Identity Cloud use HTTPS to protect the secret.
