After an Admin has been added to the app, they will have to continue with certain configurations.

Step 1: Create a Page

If a Facebook page has not been created yet, Admin can create the page where the bot will be live.

On the left sidebar, under Products, there will be a Messenger option. Go to the Settings page and when you scroll down, you will be able to see the following screen -

Click on Add or Remove Pages button.

Step 2: Generate Access Token

The access token from Facebook will be required on the Haptik Platform for the setup of bot.

You will be able to generate an access token for a Page if:

1. You are one of the Page admins, and
2. The app has been granted the Page's permission to manage and access Page conversations in Messenger.

Click on the Generate Token button. Facebook will ask to accept the terms. Once you click on I Understand checkbox, the Access Token will be available for use.

Step 3: Setting up credentials on Haptik Platform

Setting up the credentials will connect the Haptik bot to the required Facebook page. These credentials will need to be set up in the Business Manager section of the Haptik Platform.

On the Production Environment, navigate to Business Manager. Search for your business name and click on it.

Under the Channels section, there is a Platform Deployment tab. Select the Platform as Facebook to set up the following credentials.

The credentials required are -

In the Platform Deployment tab, find the Callback URL as shown below -

Copy this Callback URL. This Callback URL will be used in the Facebook App.

4. Verify Token

The token is already present on the Haptik platform.

In the Platform Deployment tab, find the token as shown below -

Copy this token. This token will be used in the Facebook App.

Step 4: Connect the Facebook App to Haptik Platform

You will have to connect the Facebook App to the Haptik Platform to receive messages and other events sent by the Messenger users.

To create the connection, go to the Settings page of Messenger and scroll down a bit to find the Webhooks section, as shown below -

Click on Add Callback URL button. 

Paste the Callback URL which you copied from the Business Manager section of Haptik Platform and paste the token in the Verify Token field which you copied from the Verify Token field of the Business Manager section of the Haptik platform.

Click on Verify and Save button.

Step 5: Subscribe to events

After adding the Callback URL you will need to Subscribe for the various events to get logs.

In the same Webhooks section, once the Callback URL is added, an Add Subscription button will appear.

Select the required events that you want to subscribe to and click on Save.

Step 6: Setup a Primary Receiver

You need to enable the App as the Primary Receiver for the Page.

Go to the Page Settings. This is the Page (not the App) where the bot will be live.

Click on the Configure button.

Select the App name from the dropdown besides Primary Receiver.

Step 7: Business Verification

If you are a developer for a business, you'll need to complete Business Verification in addition to App Review before you can access live data.

Navigate to App Settings and look for the Verification section.

Click on the Start Verification button and select the type Business Verification. Create a Facebook Business Manager account (if you don't have already) by providing your Business name, your name, and email address.

Provide the Business details and complete the verification process.

Step 8: App Review

In order to submit the App for an App review, you will have to request Advanced Access. The basic permissions that you can request are messages and messages_postbacks. Click here to read more about App Review.

• Here, Facebook will manually do an app review. You will have to inform them how to access your bot, which flows can be tried so that they can understand the bot's working in a better way. Along with that, you will also have to inform them what data are you collecting from the users during the conversation. Basically, you need to give all the required details, such that they can go through it, and review the app.
• Once you have provided Facebook with all the required information, you can submit the app for app review.
• If all the details provided by you are accurate, your app will get reviewed by Facebook, and the bot will be able to send responses to the user's messages.
