# Does Astera support extraction of data residing in online sources? Yes, Astera supports the extraction of data residing in online resources. There are various built-in features such as Cloud Storage Connection, which allows users to connect to supported cloud providers, such as Microsoft Azure Blob Storage, Amazon S3, Microsoft SharePoint and Google Cloud Storage. After connecting to the provider, the user will be able to browse files available on that cloud platform within the relevant source object. Other features to extract online data include File Transfer Protocol (FTP) which enables users to access files from a remote directory, Email Source through which we can extract file attachments from emails, Electronic Data Interchange (EDI) allowing users to exchange data with partners over all X12 and EDIFACT formats, and REST API connector which is used for sourcing data from an API. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
