How to use cURL to authenticate with OAuth 2.0 for API requests?

To authenticate with OAuth 2.0 using cURL for API requests, you can follow these steps:

1. Obtain the necessary credentials: Get the client ID and client secret from the API provider. These credentials are used to identify your application.

2. Obtain an access token: Use cURL to send a request to the authorization server's token endpoint with the necessary parameters (client ID, client secret, grant type, etc.). The response will include an access token that you'll use for subsequent API requests.

   curl -X POST -u "CLIENT_ID:CLIENT_SECRET" -d "grant_type=client_credentials" "https://authorization-server.com/token"

   Replace CLIENT_ID and CLIENT_SECRET with your actual credentials. Modify the endpoint URL as per the authorization server's documentation.

3. Make API requests: With the received access token, include it in the Authorization header of your API requests.

   curl -H "Authorization: Bearer ACCESS_TOKEN" "https://api-provider.com/api/endpoint"

   Replace ACCESS_TOKEN with the token you obtained in the previous step. Modify the API endpoint URL according to the API documentation.

By following the above steps, you'll be able to authenticate with OAuth 2.0 using cURL for making API requests.
