With the release of WhatsApp Cloud API, WhatsApp allow companies to connect directly to their API or create business accounts on their own. To create a WhatsApp Cloud API account you'll need to create your own Facebook App in order to use WhatsApp Cloud API.

Alternatively, you can create a WhatsApp Business API account you'll need to apply through a WhatsApp Partner. Once a WhatsApp Partner has approved and provisioned your WhatsApp Business API account with a phone number you may connect it to the platform and manage WhatsApp messages just like any other channel.

Messaging Window

WhatsApp API has a messaging window of 24 hours in which you are allowed to reply to customers with any content. After 24 hours, you will need to send a Template Message in order to send a reply to the customer.

The 24 hours messaging window is applicable to the following WhatsApp Channels:

WhatsApp Interactive Message

Due to the partners' limitations, WhatsApp Interactive Message is only supported by 360dialog as of now.

In, WhatsApp Interactive Message is used when sending a multiple choice question from a survey or quick replies using Dialogflow.

When the question or message has fewer or equal to 3 options, WhatsApp Quick Replies will be used to display the options.
