Cloud Storage Integrations

This section covers integrations with cloud storage providers. All cloud storage integrations use the HTTP Task with appropriate authentication methods.

Available Providers

Provider	Auth Type	S3-Compatible
AWS S3	AWS Signature V4	Yes (native)
Azure Blob Storage	SAS Token	No
GCP Cloud Storage	Service Account	No
OVH Object Storage	AWS Signature V4	Yes
Scaleway Object Storage	AWS Signature V4	Yes

S3-Compatible Providers

Many cloud providers offer S3-compatible object storage. These providers use AWS Signature V4 authentication and can be configured similarly to AWS S3:

• OVH Object Storage
• Scaleway Object Storage
• Cloudflare R2
• MinIO
• Backblaze B2

Common Operations

All cloud storage integrations support these common operations:

Operation	HTTP Method	Description
List objects	GET	List objects in a bucket/container
Upload file	PUT/POST	Upload a file to storage
Download file	GET	Download a file from storage
Delete file	DELETE	Delete a file from storage

Authentication Overview

AWS Signature V4

Used by AWS S3 and S3-compatible providers (OVH, Scaleway, Cloudflare R2, MinIO, Backblaze B2).

{
    "authentication": {
        "useAuthentication": true,
        "type": "AWS_SIGNATURE_V4",
        "accessKeyId": "${workflow.variables.access_key_id}",
        "secretAccessKey": "${workflow.variables.secret_access_key}",
        "region": "${workflow.variables.region}",
        "service": "s3"
    }
}

Azure SAS Token

Used by Azure Blob Storage. The SAS token is appended to the URL.

{
    "path": "/container/file.txt?${workflow.variables.sas_token}",
    "headers": {
        "x-ms-version": "2021-06-08"
    }
}

GCP Service Account

Used by Google Cloud Platform services.

{
    "authentication": {
        "useAuthentication": true,
        "type": "GCP_SERVICE_ACCOUNT_KEY",
        "gcpServiceAccountKeyProjectId": "${workflow.variables.gcp_project_id}",
        "gcpServiceAccountKeyPrivateKeyId": "${workflow.variables.gcp_private_key_id}",
        "gcpServiceAccountKeyPrivateKey": "${workflow.variables.gcp_private_key}",
        "gcpServiceAccountKeyClientEmail": "${workflow.variables.gcp_client_email}",
        "gcpServiceAccountKeyClientId": "${workflow.variables.gcp_client_id}",
        "gcpServiceAccountKeyScope": ["https://www.googleapis.com/auth/cloud-platform"]
    }
}
