Premiers pas avec Synthflow

Before any feature works, finish this one time setup.

Cela prend environ trois minutes.

Watch my walkthrough of the platform first:

Passons maintenant en revue chaque étape.

Étape 1 : Créez votre compte

Go to the Synthflow website and click the Get Started button.

Saisissez votre adresse courriel professionnelle et créez un mot de passe.

✓ Point de contrôle: a confirmation email lands in your boîte de réception within a minute.

Étape 2 : Connecter un numéro de téléphone

Synthflow AI runs in the browser, so there is no app to download.

Buy a number inside Synthflow, or integrate an existing number using Twilio.

Voici à quoi ressemble le tableau de bord :

✓ Point de contrôle: your number shows a green connected status.

Step 3: Feed the Agent Your Business Data

Upload PDFs or documents so the agent knows your services, hours, and prices.

No coding skills are needed at any point here.

How to Use Synthflow Smart Call Manager

Gestion intelligente des appels lets you route every inbound and outbound call to the right ai agents automatically.

Voici comment l'utiliser étape par étape.

Step 1: Open the Numbers Tab

Click Phone Numbers, then assign your number to an agent.

One number can hold separate inbound and outbound agents.

Step 2: Set Your Routing Rules

Choose what happens on busy lines and after hours.

Add a transfer number so callers reach a human when needed.

Voici à quoi cela ressemble :

✓ Point de contrôle: the call log shows your test with a full recording.

Step 3: Run a Test Call

Use the dashboard to place a live test call and listen back.

Comment utiliser le planificateur automatique de Synthflow

Automatique Planificateur lets you let the agent book appointments during the call itself.

Voici comment l'utiliser étape par étape.

Étape 1 : Connectez votre calendrier

Open Integrations and connect Google Calendar or Cal.com.

Grant booking access when the consent screen appears.

Step 2: Define Your Availability

Pick your working hours, slot length, and buffer time.

Real time booking then happens mid conversation, not after it.

Voici à quoi cela ressemble :

✓ Point de contrôle: a test booking appears on your calendar with the correct date.

Step 3: Add a Confirmation Action

Trigger an SMS or email confirmation the moment a slot is taken.

Comment utiliser le service de réponse automatisée Synthflow

Service de réponse automatisé lets you answer every caller when your team is offline.

Voici comment l'utiliser étape par étape.

Étape 1 : Choisir un modèle

Start from a pre built template such as appointment scheduling.

Templates save an hour of prompt writing on day one.

Step 2: Write the Greeting

Keep the opening line short and name your business.

Tell the agent to acknowledge the reason for the call before answering.

Voici à quoi cela ressemble :

✓ Point de contrôle: an after hours test call gets a full answer, not voicemail.

Step 3: Set an Escalation Path

Route anything the agent cannot answer to a human on request.

Comment utiliser les agents vocaux IA de Synthflow

Agents vocaux IA lets you build ai voice agents that hold real conversations with your customers.

Voici comment l'utiliser étape par étape.

Step 1: Choose Your Build Mode

Pick Flow Designer for structured logic or Single Prompt for speed.

You can create multiple agents using both approaches.

Step 2: Add Conversation Nodes

Each node in Flow Designer is one action or decision point.

Place a Conversation node before any branch so the agent waits for the answer.

Deterministic logic means the agent follows set rules rather than making its own decisions.

Voici à quoi cela ressemble :

✓ Point de contrôle: your agent greets you by name on a test call.

Step 3: Pick the Voice

Choisissez un ElevenLabs voice, then tune tone, speed, and volume.

Comment utiliser les rapports et analyses Synthflow

Rapports et analyses lets you see what your voice agents actually said on every call.

Voici comment l'utiliser étape par étape.

Step 1: Open Call History

Filter by agent, outcome, or date range.

Use search to find one caller fast.

Step 2: Read the Transcript

Open any call and read the transcript beside the recording.

Weak answers show up as long pauses or repeated questions.

Voici à quoi cela ressemble :

✓ Point de contrôle: your dashboard shows call volume, duration, and outcomes.

Step 3: Feed Fixes Back

Rewrite the prompt or add the missing fact to your knowledge base.

Share the transcript with your team so any fact you added gets checked.

Comment utiliser l'intégration de Synthflow avec WhatsApp ?

Intégration WhatsApp lets you continue the conversation on a channel people actually read.

Voici comment l'utiliser étape par étape.

Step 1: Link WhatsApp

Connect your business number in the integrations panel.

Verify ownership through the code sent to that number.

Step 2: Build the Follow Up

Write one short message the agent sends after each call.

Include the booking link or the quote you mentioned on the phone.

Voici à quoi cela ressemble :

✓ Point de contrôle: a test call ends with a WhatsApp message on your phone.

Step 3: Set the Trigger

Fire the message only on calls that end with a booking or a quote.

Comment utiliser Synthflow AI Receptionist

Réceptionniste IA lets you greet callers, qualify them, and escalate the hard ones.

Voici comment l'utiliser étape par étape.

Step 1: Define the Intake Questions

Ask name, reason for calling, and preferred callback time.

Store each answer as a variable you reference later.

Step 2: Add Lead Qualification Logic

Branch high intent callers straight to your sales line.

Send everyone else to booking or a callback queue.

Voici à quoi cela ressemble :

✓ Point de contrôle: a transferred call arrives with a summary attached.

Step 3: Turn On Warm Transfer

The agent passes call context to the human before handing over.

Comment utiliser Synthflow AI Concierge

Concierge IA lets you handle guest requests and service questions at any hour.

Voici comment l'utiliser étape par étape.

Step 1: Load Your Service Menu

Upload your list of services, hours, and prices.

Add anything guests ask about that is not on your site.

Step 2: Enable Request Handling

Let the agent take a request and log it for your team.

Cancel and reschedule flows belong here too.

Voici à quoi cela ressemble :

✓ Point de contrôle: a test request appears as a new record in your CRM.

Step 3: Connect Your CRM

Push every request into HubSpot or Salesforce natively.

How to Use Synthflow IVR Optimizer

Optimisation IVR lets you replace press one menus with plain speech.

Voici comment l'utiliser étape par étape.

Step 1: Map Your Current Menu

Write down every option callers hear today.

Most menus have three real paths and a lot of noise.

Step 2: Rebuild It as One Question

Ask callers what they need and let the agent understand the answer.

The Multi-Agent System keeps each path as its own small flow.

Voici à quoi cela ressemble :

✓ Point de contrôle: every spoken request reaches the right agent.

Step 3: Test Every Path

Call in and try each path, including the one nobody uses.

Astuces et raccourcis pour Synthflow Pro

After eight months on this platform, here are the shortcuts I actually use.

Every user gets the same constructeur, so these work at any account level.

Raccourcis clavier

Fonctionnalités cachées que la plupart des gens ignorent

• Système multi-agents : break one huge flow into small reusable sub flows that are easier to work on.
• Coutume clone vocal: upload audio samples and the tool builds a voice that sounds like your own team.
• Warm transfer context: the human who picks up hears what happened before they say hello.
• BELL framework: build, evaluate, launch, and learn is the loop Synthflow recommends for every agent.

Here is what my own account looks like after eight months of use:

Erreurs courantes à éviter avec Synthflow

Mistake #1: Branching before the agent has an answer

Mistake #2: Launching with an empty knowledge base

Mistake #3: Ignoring accents and complex questions

Dépannage de Synthflow

Problem: The agent talks over the caller

Cause: the interruption threshold is set too low for your line quality.

Réparer: raise the silence timeout by half a second and test again on a mobile connection.

Problem: Bookings are not reaching the calendar

Cause: the calendar connection expired or the account lost booking permission.

Réparer: disconnect the integration, reconnect it, and place one test call to confirm.

Problem: Your bill jumped this month

Cause: usage based billing scales with call minutes, so volume spikes hit the invoice fast.

Réparer: cap concurrent calls and check the minutes report weekly instead of monthly.

📌 Note: if none of these fix your issue, contact Synthflow support.
