Can Google Cloud Storage (GCS) be directly accessed using OAuth 2.0 Client Credentials flow (client ID + client secret) for file uploads?
Can Google Cloud Storage (GCS) be directly accessed using OAuth 2.0 Client Credentials flow (client ID + client secret) for file uploads?
I’ve encountered a limitation where GCS seems to require Service Account authentication to generate access tokens for uploading files, but I want to confirm whether OAuth 2.0 Client Credentials flow can be used, possibly with additional configurations. Any insights or best practices would be appreciated!
Using Postman got below error. "error": {
"code": 401,
"message": "Anonymous caller does not have storage.objects.create access to the Google Cloud Storage object. Permission
'storage.objects.create' denied on resource (or it may not exist).",
"errors": [
{
"message": "Anonymous caller does not have storage.objects.create access to the Google Cloud Storage object. Permission
'storage.objects.create' denied on resource (or it may not exist).",
"domain": "global",
"reason": "required",
"locationType": "header",
"location": "Authorization"
}
]
}
}
I Google and found few articles saying Google does not support auth2.0 with client id & client secret to upload file we need to use service account (which gives json & use jwt to allow access) But I want to upload file using aith2.0 with grant type client credentials. I want to integrate with this with app to upload files and app only support aith2.0 with grant type ( client credentials & password credentials) Just testing with postman but seems Google has some limitations.
