Get Credential Provider

Discovers and returns an authenticated credential object from a chain of credential providers. This function attempts each credential in the chain until one successfully authenticates, returning the first successful credential object.

Usage

get_credential_provider(
  scope = NULL,
  tenant_id = NULL,
  client_id = NULL,
  client_secret = NULL,
  use_cache = "disk",
  offline = TRUE,
  oauth_host = NULL,
  oauth_endpoint = NULL,
  chain = NULL
)

Arguments

scope

Optional character string specifying the authentication scope.

tenant_id

Optional character string specifying the tenant ID for authentication.

client_id

Optional character string specifying the client ID for authentication.

client_secret

Optional character string specifying the client secret for authentication.

use_cache

Character string indicating the caching strategy. Defaults to "disk". Options include "disk" for disk-based caching or "memory" for in-memory caching.

offline

Logical. If TRUE, adds 'offline_access' to the scope to request a 'refresh_token'. Defaults to TRUE.

oauth_host

Optional character string specifying the OAuth host URL.

oauth_endpoint

Optional character string specifying the OAuth endpoint.

chain

A list of credential objects, where each element must inherit from the Credential base class. Credentials are attempted in the order provided until get_token succeeds. If NULL, uses default_credential_chain().

Value

A credential object that inherits from the Credential class and has successfully authenticated.
