# Allo and WhatsApp: turn a missed call into a conversation

> WYP.chat connects your Allo phone system to your WhatsApp conversations. Every incoming, outgoing or missed call shows in the customer’s conversation, with its length, the team member who answered and Allo’s summary. A missed call can get a WhatsApp message two minutes later, so the customer writes to you instead. There is no Call back button: you call back from the Allo app. France only.

## Phone calls and WhatsApp in one conversation

A customer calls while you are out on a job, a colleague has already called back, someone else wants to know what was said: it all reads in one place, the customer’s conversation.

### A missed call while you are on a job

A few minutes later, the customer gets a WhatsApp message inviting them to write. They describe what they need, and your team handles it like any other conversation.

### The whole team sees the call

The call line shows the direction, the length, who answered and the number. Allo’s call summary arrives as an internal note.

### The customer chooses to be reached on WhatsApp

In Allo’s phone menu, an option called “WhatsApp message”: if the customer presses 1, their consent is recorded after the call and the message goes out, even beyond 24 hours.

## What the Allo integration does

The integration uses Allo’s official API. You paste an API key into WYP.chat, which checks it and subscribes to your calls itself: there is no webhook to set up.

- **Call log**: Every incoming, outgoing or missed call, and every voicemail, shows in the person’s WhatsApp conversation, with the length, the member who answered and the number. If the number is unknown, a contact record is created.
- **Linked team members**: Each Allo user is linked to the WYP.chat member with the same confirmed email address.
- **Listen to the recording**: On demand, for members who can see the conversation, except the Viewer role: WYP.chat asks Allo for a temporary link each time. Every playback is written to the audit log, and the audio stays with Allo.
- **Summary and transcript**: When Allo provides them, the call summary and transcript arrive as an internal note in the thread. The AI agent reads them too, as context for the conversation.
- **Missed call to WhatsApp**: With the Allô chantier pack and its Missed call scenario, a customer who got no answer receives a WhatsApp message two minutes after Allo reports the call.
- **No Call back**: Allo’s API cannot place a call: WYP.chat has no Call back button or one-click calling. You call back from the Allo app.

Missed call

## The WhatsApp message after a missed call

Two minutes after Allo reports a missed incoming call from a mobile, if nobody has called back or picked up in the meantime, WYP.chat sends the customer a WhatsApp message inviting them to write. It is the Missed call scenario in the Allô chantier pack: after every missed call, or only outside your opening hours.

[Turn on the missed call message, step by step](https://wyp.chat/en/help/appel-manque-whatsapp)

- **What counts as missed**: Ringing with no answer, the caller hanging up while it rings, or voicemail. A call taken by Allo’s AI agent or forwarded elsewhere counts as answered; a blocked or failed call never sends a message.
- **The customer wrote to you in the last 24 hours**: The WhatsApp [24-hour window](https://wyp.chat/en/glossary/fenetre-24h) is open: the message goes as free text.
- **After 24 hours**: You need a utility template approved by Meta (the pack prepares it as a draft) and the customer’s consent. You add a phone menu to your Allo call flow with an option called “WhatsApp message”: if the customer presses 1, WYP.chat reads their choice after the call and keeps the proof. This consent allows no campaign.
- **Never**: For an internal call or a withheld number, to a landline, or more than one message per number in 24 hours. STOP and refusals are respected.

## Connect Allo to WYP.chat

A few minutes, once for the whole workspace: you create the API key in Allo and paste it into WYP.chat.

Reserved for the workspace owner and admins, with the Team or Pro plan, or during the Pro trial. You also need a paid Allo plan: its API is refused during Allo’s free trial. If you record your calls, tell the caller with an announcement at the start of the call flow.

1. **Create a key in Allo**: In Allo (web.withallo.com), sign in with an Admin account, open Settings › API and create a key with the CONVERSATIONS\_READ, WEBHOOKS\_READ\_WRITE, USERS\_READ and PHONE\_NUMBERS\_READ rights. Copy it: Allo shows it only once.
2. **Paste the key into WYP.chat**: Open Settings › Workspace and members, Phone system section, choose Allo (France only) in Your phone system, paste the key and click Connect Allo. WYP.chat tests the key and creates the webhook itself.
3. **Check the users**: Each Allo user is linked to the member with the same confirmed email address. After a change in Allo, click Refresh users.
4. **Add Allô chantier and the “WhatsApp message” menu**: For the missed call message, click Add Allô chantier, choose when to send it and submit the prepared template to Meta. For consent beyond 24 hours, add a menu to your Allo call flow with an option called “WhatsApp message” on key 1: the screen gives you the announcement to record.

## What the integration does not do (yet)

So you know what to expect:

- No Call back button or one-click calling: Allo’s API cannot place a call.
- France only, for now.
- Recordings are not copied to WYP.chat: playback goes through Allo, on demand.
- Calls, summaries and consents are deleted from WYP.chat after 6 months.
- No WhatsApp message after an internal call, a withheld number or a call from a landline, and never more than one per number in 24 hours.
- A call that WYP.chat did not receive from Allo is picked up within 10 minutes, but without the “press 1” choice made in the phone menu.
- One phone system per workspace: to move from Ringover to Allo, disconnect Ringover first.

## Frequently asked questions

### Allo already sends a text after a missed call, why use WhatsApp?

Allo does offer an automatic text from your number, according to its missed call page. With WYP.chat, the message goes out on WhatsApp and the customer’s reply lands in the team’s shared inbox, with assignment, internal notes and the AI agent.

### Do I need a particular Allo plan?

You need a paid Allo plan: its API is refused during the free trial, and WYP.chat tells you so when you connect. On the WYP.chat side, you need the Team or Pro plan, or the Pro trial.

### Can I call the customer back in one click from WYP.chat?

No. Allo’s API cannot place a call, so WYP.chat has no Call back button for Allo. You call back from the Allo app. With Ringover, the Call back button exists.

### Are my calls recorded at WYP.chat?

No. The recording stays with Allo: WYP.chat asks for a temporary link only when a member clicks Listen, and every playback is written to the audit log. Calls, summaries and consents are deleted from WYP.chat after 6 months.

### Do I need the customer’s consent to write after their call?

If they wrote to you on WhatsApp in the last 24 hours, the message goes as free text. Otherwise you need a template approved by Meta and the customer’s consent, collected by an Allo phone menu with a “WhatsApp message” option when they press 1. This consent covers that message only, never a campaign.

### What if I am not in France?

The Allo integration is offered for France only, for now. Ringover is the other phone system connected to WYP.chat.
