DepPipeline1 and ADFPipeline1 share a credential stored in Vault1. To configure ADFPipeline1 to retrieve the credential from Vault1, which Azure Data Factory activity type should you use?

The Web activity in Azure Data Factory (ADF) is designed to call a REST endpoint, which is precisely how you would interact with Azure Key Vault (Vault1) to retrieve secrets or credentials. You would configure the Web activity with the Key Vault REST API endpoint for secret retrieval and appropriate authentication. Lookup activity is used to read data from a data source or a configuration file. Get Metadata activity retrieves metadata of a data object. Copy activity is used to copy data between data stores. None of these are designed for direct REST API calls to a service like Azure Key Vault for credential retrieval.
