Handles the incoming HTTP request and performs authentication and authorization checks based on paths starting with /i/.

Details

This function is the entry point for the WebhookAuth plug. It first checks if the request path starts with /i/ to determine whether the request should be processed by this plug.

If the path matches, it then extracts the webhook part from the request path and runs to fetch the corresponding trigger using the fetch_trigger function.

If a valid trigger is found, the function proceeds to validate the authentication of the request using the validate_auth function.

In case the trigger is not found, or the path does not start with /i/, the function returns a 404 Not Found response with a JSON error message indicating that the webhook is not found.

Parameters

• conn: The connection struct representing the incoming HTTP request.
• _opts: A set of options, not used in this function but is a mandatory parameter as per Plug specification.

Returns

• A connection struct representing the outgoing response, which can be a successful response, an unauthorized response, or a not found response, based on the evaluation of the above-mentioned conditions.

Examples

Assuming a request with the path /i/some_webhook:

Webhook Found and Authenticated

iex> LightningWeb.Plugs.WebhookAuth.call(conn, [])
%Plug.Conn{status: 200, ...}

iex> LightningWeb.Plugs.WebhookAuth.call(conn, [])
%Plug.Conn{status: 404, ...}

Initializes the options.
