# Linking with login on the provider's site

> The steps common to Facebook, Instagram, WhatsApp Aziendale and TikTok: the provider's window, choosing the page or number, the time limit (10 minutes), the error messages and what to do.

Last updated: 23 October 2026. Source: https://narciso.io/en/docs/percorso-guidato/

Facebook, Instagram, WhatsApp Aziendale and TikTok are linked with an «official» login **on the provider's site** (Meta, Instagram or TikTok): you never type the password into Narciso. The screens are the same for all four; only the titles, colours and texts change. Only the **Titolare** (owner) can do it ([Linking channels](https://narciso.io/en/docs/collegare-i-canali/)).

## Before you start

- **Allow pop-ups** for the Narciso site: the provider's page opens in a **separate window** (about 680 × 760 points, with the address bar visible).
- Have the **right account** for that provider ready: it asks you to log in, if you are not already, and to **authorise** Narciso.
- Have the page, profile or number you want to link ready.

## The steps

1. **Click the card** of the channel (or «Ricollega» (Link again)). In Narciso, «**Collega** [channel]» (Link [channel]) appears with a spinning circle, the text «**Continua sulla pagina ufficiale di** [Meta / Instagram / TikTok]» (Continue on the official page of [Meta / Instagram / TikTok]) and «Completa l'accesso nella finestra … appena aperta. Questa schermata si aggiornerà automaticamente.» (Complete the login in the window … that has just opened. This screen will update automatically.)
2. **In the provider's window**, log in and grant the permissions. The screens belong to the provider and may change without notice.
3. **The return.** When the login is finished, the window briefly shows a blank Narciso page and closes by itself. If it cannot close, «**Collegamento completato** — Puoi chiudere questa finestra e tornare all'app.» (Link completed — You can close this window and go back to the app.) appears.
4. **«Recupero account…»** (Retrieving account…): for a few seconds Narciso reads the list of pages, the profile or the numbers from the provider. No access key passes through your browser: the browser receives only the names to display.
5. **The choice.** Each row has a photo (or a circle with the initial), a name, a subtitle and a selection circle. If there is only one entry, it is already selected.
6. **Continua** (Continue). The button stays off until you select a row; **Annulla** (Cancel) goes back. «Salvataggio collegamento…» (Saving link…) appears, then the window closes and the green success notice appears at the top.

> **Warning.** The «Collegamento completato» message in the small window appears **even** when the provider answered with an error or when you refused the authorisation. It does not mean the link succeeded: what counts is what the main Narciso window shows. The small window has to be closed by hand.

### What you authorise

| Channel | What it asks the provider for |
|---|---|
| **Facebook** | See the pages, read content and interactions, manage the page settings to receive messages, **send and receive messages**, **publish** posts, manage comments and interactions, manage the business account, read the **statistics** |
| **Instagram** | Basic profile information, **publish** content, manage **comments**, read the **statistics**, manage **direct messages** |
| **WhatsApp Aziendale** | Manage the WhatsApp Business account, **send and receive messages**, manage the business account |
| **TikTok** | Basic profile information, publish videos |

If a permission is refused or removed, the link may fail or work only partly (without the permission on messages, for example, chats do not arrive).

### What you choose

| Channel | Title | What appears |
|---|---|---|
| Facebook | **Scegli la pagina Facebook** (Choose the Facebook page) | The pages you manage: name and category |
| Instagram | **Conferma il profilo Instagram** (Confirm the Instagram profile) | A single row: your @username |
| WhatsApp Aziendale | **Scegli il numero WhatsApp** (Choose the WhatsApp number) | The numbers of the WhatsApp Business account: verified name and number |
| TikTok | **Conferma l'account TikTok** (Confirm the TikTok account) | A single row: your @name |

You link **one entry at a time**. To link two Facebook pages (for example one for each location), repeat the procedure ([Multiple locations and shared channels](https://narciso.io/en/docs/canali-e-sedi/)).

### The success notices

| Channel | Green notice |
|---|---|
| Facebook | «Pagina Facebook collegata con successo» (Facebook page linked successfully) |
| Instagram | «Profilo Instagram collegato con successo» (Instagram profile linked successfully) |
| WhatsApp Aziendale | «Numero WhatsApp Business collegato con successo» (WhatsApp Business number linked successfully) |
| TikTok | «Account TikTok collegato con successo» (TikTok account linked successfully) |

## Time limit

The link must be completed **within 10 minutes** of opening the provider's window. After that, «**State scaduto (>10 min)**» (State expired (>10 min)) appears (on returning from the provider) or «**Sessione di collegamento scaduta, riprova**» (Link session expired, try again) (if you lingered on the choice): you start again from the grid.

## If something goes wrong

An error icon with a sentence appears in place of the circle. The buttons are **Annulla** and the **✕** at the top right, which take you back to the grid: to try again, click the card again.

| Message | When | What to do |
|---|---|---|
| «Il browser ha bloccato la finestra di [Meta / Instagram / TikTok]. Consenti i popup e riprova.» (The browser blocked the [Meta / Instagram / TikTok] window. Allow pop-ups and try again.) | The browser prevented it from opening | Allow pop-ups for the site and try again |
| «La finestra di [Meta / Instagram / TikTok] è stata chiusa prima di completare il collegamento.» (The [Meta / Instagram / TikTok] window was closed before the link was completed.) | The provider's window was closed before the end (it can also appear if it closed by itself without handing over the result) | Try again |
| «Collegamento annullato su [Meta / …].» (Link cancelled on [Meta / …].) or a sentence from the provider, often in English | Authorisation refused or provider error | Try again, granting the permissions |
| «Errore durante l'avvio del collegamento [canale].» (Error while starting the [channel] link.) | Narciso could not prepare the provider's address | Try again; if it happens again, contact support ([Support](https://narciso.io/en/docs/assistenza/)) |
| «Errore scambio code-token», «Errore recupero pagine», «Errore recupero profilo TikTok», «State OAuth non valido» (Token exchange error, Error retrieving pages, Error retrieving TikTok profile, Invalid OAuth state) | The provider did not accept the authorisation or did not return the data | Start again from the beginning |
| «Errore durante il recupero degli account.» (Error while retrieving the accounts.) | Narciso could not read the pages or numbers | Try again |
| «Nessuna pagina Facebook trovata su questo account.» (No Facebook page found on this account.) | The account does not manage any pages, or no page was selected in the Meta window | Try again, selecting the page |
| «Nessun numero WhatsApp Business trovato. Configura un account WhatsApp Business su Meta e riprova.» (No WhatsApp Business number found. Set up a WhatsApp Business account on Meta and try again.) | No number in the Meta account | Set up a number on Meta and try again |
| «Nessun profilo Instagram Business trovato. Assicurati che l'account sia un profilo Professionale/Business.» (No Instagram Business profile found. Make sure the account is a Professional/Business profile.) | The profile is not professional | Switch the profile to professional from the Instagram app ([Instagram](https://narciso.io/en/docs/instagram/)) |
| «Nessun account TikTok trovato.» (No TikTok account found.) | TikTok did not return an account | Try again |
| «Questo account è già collegato a un altro account Narciso. Scollegalo da lì prima di collegarlo qui.» (This account is already linked to another Narciso account. Unlink it from there before linking it here.) | The page, profile, number or TikTok account is already linked to **another salon** on Narciso (it is not an error if it is already linked to another location of **your** salon) | Unlink it from the other account, then try again |
| «Questo numero è riservato alla piattaforma e non può essere collegato.» (This number is reserved for the platform and cannot be linked.) | (WhatsApp Aziendale) It is the number Narciso uses to verify users | Choose another number |
| «Impossibile attivare la ricezione dei messaggi: …» (Unable to activate message reception: …) | (WhatsApp Aziendale) Meta did not activate message forwarding, or the network towards Meta did not respond | Try again and check the WhatsApp Business account on Meta |
| «Errore durante il salvataggio del collegamento.» (Error while saving the link.) | Unexpected error | Try again |
| «Operazione riservata al Titolare.» (Operation reserved for the Titolare.) | You are not the Titolare | The Titolare does it |

## After saving

- **Facebook**: Narciso subscribes to the page's notifications, to receive messages, and loads the **posts of the last 12 months** in the background. If the subscription to the notifications fails, no error appears: messages might not arrive ([Common problems with channels](https://narciso.io/en/docs/problemi-dei-canali/)).
- **Instagram**: subscription to the profile's notifications for messages and comments, and background loading of the posts of the last 12 months.
- **WhatsApp Aziendale**: Narciso subscribes your account to the notifications **before** saving; if Meta refuses, nothing is saved.
- If the **same account** is already linked by another location of your salon, nothing is redone with the provider: only the location is added ([Multiple locations and shared channels](https://narciso.io/en/docs/canali-e-sedi/)).
