The update_user.js module provides two functions for modifying user credentials: update_email and update_password. Both update Firebase Authentication directly using the Admin SDK.

​
Functions overview

FunctionWhat it updates
update_emailFirebase Auth email + Firestore email field + date.last_update
update_passwordFirebase Auth password only

​
update_email

Updates a user’s email address in Firebase Authentication and then updates the matching document in the specified Firestore collection.

​
Endpoint

POST https://<region>-<project>.cloudfunctions.net/update_email

​
Request

​
data.uid
string
required
The Firebase Authentication UID of the user whose email is being updated.
​
data.email
string
required
The new email address to set.
​
data.emailold
string
required
The user’s current (old) email address. Used to locate the Firestore document to update.
​
data.collection
string
required
The Firestore collection containing the user’s document. One of u_clients, u_collaborators, or u_staff.
{
  "data": {
    "uid": "abc123xyz",
    "email": "[email protected]",
    "emailold": "[email protected]",
    "collection": "u_clients"
  }
}

​
What it does

  1. Calls auth.updateUser(uid, { email }) to update the email in Firebase Authentication.
  2. Queries {collection} for documents where email == emailold.
  3. For each matching document, updates:
    • email → the new email address
    • date.last_update → Timestamp.now()

  "message": "Usuario: Email No Actualizado!!",
  "status": 400,
  "data": {
    "update": false,
    "error": {
      "code": "auth/email-already-exists",
      "message": "The email address is already in use by another account."
    }
  }
}
If the Firebase Authentication update fails, the Firestore document is not modified. If the Auth update succeeds but the Firestore update fails, the function still returns 200 — ensure your application handles this potential inconsistency.

​
update_password

Updates a user’s password in Firebase Authentication.

​
Endpoint

POST https://<region>-<project>.cloudfunctions.net/update_password

​
Response

Success (200): 
{
  "message": "Usuario: Password Actualizado!",
  "status": 200,
  "data": { "update": true }
}
Error (400): 
{
  "message": "Usuario: Password No Actualizado!!",
  "status": 400,
  "data": {
    "update": false,
    "error": {}
  }
}
The update_password function updates Firebase Authentication only. No Firestore fields are modified when changing a password.
