# Google Cloud Storage If you use Google Cloud Storage (GCS) to store data, you can send attachments as `https:` or `http:` URLs. You can also send attachments as `gs:` [protocol URIs](https://cloud.google.com/storage/docs/gsutil) which look like `gs://bucket/key`. To access private GCS objects, We use **Cross-Project Access**. ## **Cross-project Access** We will fetch attachments from your GCS bucket, using our GCP service account `ti-it-sa-gtstudio@ti-ai-computervision-prod.iam.gserviceaccount.com`. You will need to grant access to TELUS International on a per-bucket basis using [Cloud IAM permissions](https://cloud.google.com/storage/docs/access-control/using-iam-permissions) or set permissions on objects [using ACLs](https://cloud.google.com/storage/docs/access-control/create-manage-lists). #### An example on how to provide access to a particular folder inside the bucket using ACLs Install and set up gsutil - and run the below command ``` gsutil acl ch -r \ -u ti-it-sa-gtstudio@ti-ai-computervision-prod.iam.gserviceaccount.com:O \ gs://example-bucket/folder/ ``` For more info on how to control access to the buckets and objects in GCS using ACLs, please refer this [doc](https://cloud.google.com/storage/docs/gsutil/commands/acl). --- # 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. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://annotationdocs.telusinternational.com/secure-attachment-access/gcp-iam-access.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
