Answer
As was answered in previous posts, Get Only documents names in Firestore [duplicate], you can use REST API list call to return documents’ names from a specific collection.
Here is an example that lists documents of a collection and saves it to a text file (docs.txt):
curl GET "https://firestore.googleapis.com/v1beta1/projects/{project-ID}/databases/(default)/documents/{collection-name}" > docs.txt
You need to replace the {project-ID} with your project ID in Firestore and {collection-ID} with your collection name respectively.
