Hi I am creating documents with commit like this way:

{
    "writes": [
        {
            "update": {
                "name": "projects/projectID/databases/(default)/documents/test/?documentId=",
                "fields": {
                    "comment": {
                        "stringValue": "Hello World!"
                    }
                }
            }
        },
        {
            "update": {
                "name": "projects/projectID/databases/(default)/documents/test/?documentId=",
                "fields": {
                    "comment": {
                        "stringValue": "Happy Birthday!"
                    }
                }
            }
        }
    ]
}

The parameter ?documentId= dosen´t work like when creating a single document, if I left empty I get an error that I must specify the name of the document so how I can generate an automatic id for each document?

Unfortunately, batch commits with auto generated documentId are not possible in the Firestore REST API. As you can see in this documentation, the Document object should be provided with a full path, including the documentID:

“Name:string
The resource name of the document, for example projects/{project_id}/databases/{databaseId}/documents/{document_path}.”

And if it was possible to omit the documentID, it would be mentioned in this documentation.

If you would like to have this implemented in the Firestore REST API, you can create a feature request in Google’s Issue Tracker so that they can consider implementing it.
