Important: It is not always possible to restore a deleted service account. Use this method only as a last resort.
After you delete a service account, IAM permanently removes the service account 30 days later. There is no way to restore a deleted service account that has been permanently removed.
HTTP request
POST https://iam.googleapis.com/v1/{name=projects/*/serviceAccounts/*}:undelete
As an alternative, you can use the - wildcard character instead of the project ID:
projects/-/serviceAccounts/{EMAIL_ADDRESS}
projects/-/serviceAccounts/{UNIQUE_ID}
When possible, avoid using the - wildcard character, because it can cause response messages to contain misleading error codes. For example, if you try to access the service account projects/-/serviceAccounts/fake@example.com, which does not exist, the response contains an HTTP 403 Forbidden error instead of a 404 Not
Found error.
Authorization requires the following IAM permission on the specified resource name:
iam.serviceAccounts.undelete
Request body
The request body must be empty.
Response body
If successful, the response body contains data with the following structure:
