Consider that to use WhatsApp, on XCALLY side you need to enable the connector, while for interactions management you need to consult the official documentation of the selected provider to check prices: find out Sinch documentation at this link

SINCH account

By the end of September 2023 v1 SINCH version will be deprecated as indicate in the official SINCH portal:[...]“Support for the standalone WhatsApp API will end on September 30, 2023. New customers must use, and existing customers must migrate to, the WhatsApp channel of the Conversation API. Any migration must be completed prior to September 30, 2023[...] “
(for more information https://developers.sinch.com/docs/whatsapp/migration-guide/overview/)

To continue using SINCH provider you must upgrade Motion to v 3.22.0 and use SINCH v2.

There are two important sections on SINCH:

  • Whatsapp (“old section” for Whatsapp API)

  • Conversation API → new section to configure SINCH v2

On Whatsapp section you can access to Senders, so telephone numbers approved by Meta which can receive and send new interactions. Configure senders is essential for getting Whatsapp working.

Only incoming chats from Whatsapp where agents reply are supported in Conversation API implementation (not message templates for outbound)

How to configure a Whatsapp Channel on Conversation API

  • You need to create a Project: company or partner’s customer

  • Configure app which can be considered like an aggregator of service channels. App can have 1 channel of each type, but 1 telephone number allows only the creation of 1 app.

On SINCH we support only Instagram and Whatsapp

  • two available regions, USA and EU, depending on customer's number: insert EU if it is an European number or USA if it is an American number

If you have doubts about region, you can ask to SINCH support

  • Clicking on the created app, you can edit it from configuration section, by modifying the name (not recommended action)

  • Processing Mode: Conversation mode

It is essential to select this mode to allow Motion to reply to customer messages (without it, client id is not sent with the message, so messages arrive from SINCH to Motion as "Fire and forget" (so only as notification).

  • On Set up channels you can setup app connections
    As reference guide to create another channel, you can use Instagram via conversation API.

Whatsapp setup can only be done with SINCH.

You need to ask to your account manager to associate phone number to this app, sending an email to your account manager.
If you already have contacts with Whatsapp API, you can speak with the same account manager, otherwise you can request contact from Overview section → Get Started

In your email for account manager, you have to send your:

  • SINCH App ID: you can copy it from Conversation API→ Apps

  • SINCH Project ID: you can copy it from Conversation API→ Overview

How Admin can configure SINCH on Motion

☑️ The Motion instance must have a public address accessible via HTTPS. For security reasons we strongly recommend to use a Reverse Proxy → find out more

☑️ Motion instance must have valid certificate

☑️ License with Whatsapp Channel enabled


Create a Webhook

First of all you need to insert Motion URL in Apps section → Webhooks
To create a new webhook you can click on Add Webhook

  • target type: HTTP

  • target url: composed by https://{MOTION_URL}/api/whatsapp/accounts/{WHATSAPP_CONNECTOR_ID}/notify
    If not sure, there is a cortesy URL ready to be copy pasted in Whatsapp Connector → Whatsapp Accounts → Settings → Receive URL

  • secret token for security to prevent a third element from sending messages

  • triggers: you must add all available triggers

OAuth2 authentication is not supported, authentication is via secret token

  • Click on Create

Create a new Whatsapp Account

On Motion, as Admin you can create a new Whatsapp Account from WhatsApp Connector section.

  • Name

  • Key

  • Choose a List

  • Proxy or Motion Domain: public ID (important also for attachments that will be downloaded from here)

  • Type = Sinch V2

  • Base URL = EU Production or US Production which must be equal to region inserted in app

  • SINCH Project ID to copy from Conversation API → Overview

  • SINCH App ID to copy from Conversation API → Overview

  • SINCH Key ID to create in Settings → Access Keys → New Key

When you create a New Key, you will view a visible Key ID and a Key Secret which will disappear, so you need to copy it immediately to insert it on Motion.
These two keys are associated to project

  • SINCH Key Secret value from Settings → Access Keys

  • SINCH webhook optional added security token: secret token created before

  • Phone: phone number inserted in SINCH with prefix ( Conversation API → Apps)

  • Optional description

And click ADD


Then you need to add agents or queue to the created Whatsapp Account to manage interactions.

Editing the account, you can see on Settings → General → Receive URL your url including tokens.

To change settings you can edit them in Advanced section:

Use Whatsapp Connector with SINCH for Agents

For Agents, the feature is available on Whatsapp Connector section, from which they have to select accounts.
In fact agents need to enable the new created account connected to SINCH V2 to receive new interaction from this account

How to migrate from Whatsapp API to Conversation API

If you want to migrate using SINCH V2, it means that you have already a Whatsapp API with a configured sender

On SINCH side you need to:

(These parameters are essential to configure the new Whatsapp Connector Account on Motion side)

  • Create Webhook App in SINCH Conversation API → Apps → Webhooks and in target url you can insert: https://{MOTION_URL}/api/whatsapp/accounts/{WHATSAPP_CONNECTOR_ID}/notify

On Motion side, you should have already a Whatsapp Account with Whatsapp API.

  • (warning) To avoid service interruptions, we suggest you create a new Whatsapp Account SINCH V2. Be careful that once the migration will take place, messages arrive on the new account (For reports it’s important to consider it, because you will find interaction only on this new account). So you need to create a new one with the same:

    • settings: list, notification template, transfer options, routing parameters, dispositions, canned answer

    • action flow

    • (info) associated queue and agents. It’s very important to add permissions to agents to allow the receiving of interactions

Useful Tip: you can create a queue, by associating both the old and the new account, so you are sure that all interactions will arrive in the queue and when the switch will be complete, there will be continuity on the queue

  • In this account you need to insert parameters related to SINCH Conversation API Project (SINCH Project ID, SINCH App ID, API Key, Key Secret) created before

  • Moreover you need to copy Motion Url, Whatsapp Connector ID account and secret token to configure Webhook App on SINCH side

Then you must ask to your account manager to switch from Whatsapp API to SINCH V2 (to associate sender phone number to the new App project) sending by email:

  • SINCH App ID: you can copy it from Conversation API→ Apps

  • SINCH Project ID: you can copy it from Conversation API→ Overview

(tick) When account manager confirms migration finalisation, messages will pass via Conversation API

Remember that after migration interactions will be available only on SINCH V2 Account (and not more on old one).
Moreover old interactions will not continue on the new account, even if the phone number will be the same.
Check that you have correctly added agents and action flow for the successful reception of interactions
