ON THIS PAGE:

There are two important sections on SINCH:

• WhatsApp (“old section” for WhatsApp API, so SINCH V1, deprecated by the end of September 2023)

• Conversation API → 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.

Senders can have associated Message Templates, so predefined messages approved by Meta that can be used to start new interactions with customers.

• 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

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

• Processing Mode: Conversation mode

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

• 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

• Click on Create

• 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

• 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

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:

On SINCH side you need to:

• Configure a Conversation API Project, creating:

  • Project

  • App on SINCH

  • Api Key / Key Secret

(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.

• 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

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

• 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
