Google Cloud Storage Operations Reference

Orkes Conductor integrates with Google Cloud Storage to let you manage buckets and objects directly from your workflows. Once you configure the Google Cloud Storage integration, you can use the following operations to upload, download, and manage data in Google Cloud Storage without leaving your workflow.

This page covers the parameters and expected output for each operation available in the Google Cloud Storage integration.

Upload Object From Base64

Upload a file to a Google Cloud Storage bucket using base64-encoded content.

Input Parameters

Parameter	Description	Type	Required/Optional
Object Name	The name of the object to upload, including any folder path (e.g., folder/file.txt).	string	Required.
Content Type	The MIME type of the object (e.g., text/plain, image/png).	string	Optional.
Base 64 Content	The base64-encoded content of the file to upload.	string	Required.
Bucket Name	The name of the bucket to upload the object to. If not specified, uses the default bucket configured in the integration.	string	Optional.

Output Parameters

The output is a JSON object containing the bucket name, object name and path, file size in bytes, MIME type, generation number for versioning, a direct download URL, and the creation and last-updated timestamps in Unix milliseconds.

Download Object Base64

Retrieve an object's content from a Google Cloud Storage bucket as base64-encoded data.

Input Parameters

Parameter	Description	Type	Required/Optional
Object Name	The name of the object to retrieve, including any folder path (e.g., folder/file.txt).	string	Required.
Bucket Name	The name of the bucket to retrieve the object from. If not specified, uses the default bucket configured in the integration.	string	Optional.

Output Parameters

The output contains the bucket name, object name, base64-encoded content of the retrieved object, and its MIME type.

List Objects

List objects in a Google Cloud Storage bucket, with optional prefix filtering.

Input Parameters

Parameter	Description	Type	Required/Optional
Bucket Name	The name of the bucket to list objects from. If not specified, uses the default bucket configured in the integration.	string	Optional.
Prefix	A prefix to filter objects by (e.g., reports/2025/). Returns all objects if not specified.	string	Optional.
Max Results	The maximum number of objects to return. Defaults to 100.	integer	Optional.

Output Parameters

The output contains a list of objects in the bucket, where each object includes its bucket name, object name and path, file size in bytes, MIME type, generation number for versioning, a direct download URL, and the creation and last-updated timestamps in Unix milliseconds.

Update Object

Replace an object's content or update its metadata in Google Cloud Storage. If base64-encoded content is provided, the object's data is replaced; otherwise, only the metadata is updated.

Input Parameters

Parameter	Description	Type	Required/Optional
Object Name	The name of the object to update, including any folder path (e.g., folder/file.txt).	string	Required.
Content Type	The new MIME type for the object (e.g., application/json).	string	Optional.
Base 64 Content	The new base64-encoded content to replace the object's data. Omit to update metadata only.	string	Optional.
Bucket Name	The name of the bucket containing the object. If not specified, uses the default bucket configured in the integration.	string	Optional.

Output Parameters

The output contains the bucket name, object name and path, file size in bytes, updated MIME type, generation number for versioning, a direct download URL, and the creation and last-updated timestamps in Unix milliseconds.

Delete Object

Permanently remove an object from a Google Cloud Storage bucket.

Input Parameters

Parameter	Description	Type	Required/Optional
Object Name	The name of the object to delete, including any folder path (e.g., folder/file.txt).	string	Required.
Bucket Name	The name of the bucket containing the object. If not specified, uses the default bucket configured in the integration.	string	Optional.

Output Parameters

Returns true if the object was successfully deleted.

List Buckets

List all Google Cloud Storage buckets in the project.

Input Parameters

Parameter	Description	Type	Required/Optional
Max Results	The maximum number of buckets to return. Defaults to 100.	integer	Optional.

Output Parameters

The output contains a list of buckets in the project, where each bucket includes its name, geographic location, storage class, whether object versioning is enabled, and the creation and last-updated timestamps in Unix milliseconds.

Create Bucket

Provision a new Google Cloud Storage bucket.

Input Parameters

Parameter	Description	Type	Required/Optional
Bucket Name	A globally unique name for the new bucket.	string	Required.
Location	The geographic location for the bucket (e.g., US, EU, ASIA).	string	Optional.
Storage Class	The storage class for the bucket. Supported values: STANDARD NEARLINE COLDLINE ARCHIVE .	string	Optional.

Output Parameters

The output contains the name, geographic location, storage class, whether object versioning is enabled, and the creation and last-updated timestamps in Unix milliseconds for the newly created bucket.

Get Bucket
