Authenticate with Canvas LMS API — canvas

This function handles authentication with the Canvas LMS API. It uses the provided API key and base URL, or falls back to the CANVAS_API_KEY and CANVAS_BASE_URL environment variables if none are provided.

Usage

canvas_authenticate(api_key = canvas_api_key(), base_url = canvas_base_url())

Arguments

api_key: The API key for authenticating with the Canvas LMS API. Defaults to the CANVAS_API_KEY environment variable.
base_url: The base URL of the Canvas instance. Defaults to the CANVAS_BASE_URL environment variable.

Value

A list containing the authenticated 'api_key' and 'base_url'.

Note

The function verifies authentication by making a test request to the /api/v1/users/self endpoint of the Canvas instance. If the response status code is not 200, it throws an error message indicating that authentication failed.

Examples

if (FALSE) { # \dontrun{
# Authenticate with the Canvas LMS API
api_key <- "your_api_key"
base_url <- "https://canvas.example.com"
canvas <- canvas_authenticate(api_key, base_url)
} # }
