FAQ and Troubleshooting

What are the requirements for phone number to be used to sign up for WhatsApp Business API?

  • The phone number used for WhatsApp Business API can’t be used in the WhatsApp Personal or Business app. You'll have to delete the account on WhatsApp Personal or Business app before you can use the number to sign up for WhatsApp Business API.

  • You can still use the phone number for other purposes, such as calling and receiving SMS after registering it on the WhatsApp Business Platform.

Unable to Receive Read Receipts

When the user connected to WhatsApp Business API changes their Facebook password, the permissions will be outdated and need to be refreshed. Follow these steps to refresh the permissions:

Step 1: Navigate to Settings module > click Channels > locate WhatsApp Business API Messenger channel > click Troubleshoot.

Step 2: Click Refresh Permission to refresh WhatsApp permissions.

Step 3: Send a test message to the WhatsApp phone number and check if you're able to receive the read receipts.

Can I view my conversation insights for my WhatsApp Business Account?

Yes, you can monitor your messaging and spending analytics in real-time for your WhatsApp Business Account in the Insights tab of your Meta WhatsApp Manager. Read more here.

Why do I see duplicate Contacts from the same WhatsApp channel?

WhatsApp passes the Contact’s phone number in a format that is different from the E.164 format that IS-Messenger uses. This difference causes Contacts from certain countries to be duplicated.

How do I get my business name to be shown to my contacts on WhatsApp rather than my business number?

Standard WhatsApp Business API Accounts display the business number rather than the name. To display your business name to Contacts even if they haven't added your business to their address book, you will need a WhatsApp Official Business Account.

Official Business Accounts have a green tick next to the business name, and usually only large, high-profile businesses will be given this status. Learn more about how to apply for an Official Business Account here.

What is WhatsApp Catalog and how can I use it?

WhatsApp Catalog is a feature that allows you to create a catalog of your products and share it with your customers. We have a feature request for this to be implemented in our platform. If you think this feature is valuable to you, you can upvote the feature request here.

Can a subsidiary company or an agency register a WhatsApp Business Account on behalf of another company?

Yes, they can. However, the Meta Business Account and business information used to register the WhatsApp Business Account must belong to an entity that can be verified with the relevant legal documentation. Learn more about Meta Business Verification here.

How many phone numbers can a business register when signing up for a WhatsApp Business API account and How can I Increase that limit?

When a business signs up for a WhatsApp Business API account and is unverified, they can register up to 2 phone numbers only. Verified businesses have the ability to register more phone numbers. They may register up to 20 phone numbers for a single Business Manager.

If you are stuck at a lower number, such as 5 phone numbers, and are unable to register additional numbers, you can submit a ticket directly to Meta to request an increase in the phone number limit.

Why does the message enter as an unsupported message with error code: 131051?

Why am I receiving an error message stating "Undefined: Receiver is incapable of receiving this message" when trying to send messages?

Ensure that the Contact receiving the message:

Ensure you have a Valid Website: Update your business information in the Meta Business Manager (MBM) to include a valid and clear website that showcases the nature and details of your business.

Why did I receive this error "Business eligibility payment issue" when sending a message?

This error may occur when you have recently deleted a Channel and tried to send a WhatsApp message template or start a new conversation using a different WhatsApp Business number. This is due to the credit line being released from your deleted Channel's phone number and redistributed to your remaining phone numbers. This process can take up to 5 minutes. We recommend waiting for 5 minutes before sending the message again.

This error will only occur if you have more than one number under the same Business Manager and those numbers are connected to the platform.

Can my WhatsApp API number connected to a WhatsApp Business Account (WABA) registered in Business Suite directly connect to IS-Messenger?

No, it is not possible for your WhatsApp API number that's connected to a WhatsApp Business Account (WABA) registered in Business Suite to directly connect to IS-Messenger.
