This connector allows to upload files to Azure blob storage.

Creating Azure Blob Storage

On Azure portal make these steps to be able to upload files to Azure blob:

  1. Create storage account (account name)
  2. Create container in this storage account (container name)
  3. Setup authorization by shared access signature (SAS) that will have permissions for write to created container (SAS Token).


Configure connector based on each steps before (account and container name and SAS token).

Input Example

Input has following properties: - BlobName - it can be file name with extension and if you use forward slashes it will be visible as in directories, but it is just virtual structure - Data - base64 data of file

Following data from JS Mapper

        "BlobName": "folder1/folder2/test.txt",
        "Data": "ewogICAgIlN1Y2Nlc3MiOnRydWUKfQ=="
        "FileName": "root.txt",
        "Data": "ewogICAgIlN1Y2Nlc3MiOnRydWUKfQ=="
will be uploaded to Azure blob container.
