Deck authenticates with data source
Deck establishes a connection with the data source on behalf of your user, handling MFA if required.

Access token delivered via webhook
Once authentication succeeds, Deck sends an
access_token to your webhook endpoint.5

access_token to run jobs and access data on behalf of your user.
