  • You can still use the number for other purposes, such as calling and receiving SMS after registering it on the WhatsApp Business Platform.
  • Once you use a phone for WhatsApp Cloud API you can no longer use that number on the WhatsApp Business App.

Is Business Verification needed to start using Cloud API?

It isn’t mandatory to complete Facebook Business Verification to start sending messages on WhatsApp. Without business verification, your business will still be able to:

  • Respond to unlimited user-initiated conversations.
  • Send business-initiated conversations (message templates) to 250 unique customers in a rolling 24-hour period.
  • Register up to 2 phone numbers.

Businesses can initiate Business Verification only when they're ready to scale business-initiated conversations or want to become an Official Business Account.

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.

What are WhatsApp messaging limits?

Messaging limits determine the maximum number of business-initiated conversations each phone number can send in a rolling 24-hour period. These limits do not apply to user-initiated conversations. A business-initiated conversation starts when the first message is delivered to a customer and ends 24 hours later. Read more here.

How do I add a payment method to my WhatsApp Business Account?

You can add a payment method to your Whatsapp Business account in Business Manager. Learn how to add a payment method to your WhatsApp Business Account here.

Why did my message fail to send with an error "Business eligibility payment issue"?

This is most likely due to you exceeding the monthly free tier threshold without a valid payment method. To resolve this issue, add a valid payment method.

What is WhatsApp Cloud API pricing?

WhatsApp API uses a conversation-based pricing model that charges businesses for the number of conversations they have. A conversation starts when your business' message is delivered to a customer and lasts for a 24-hour customer service window, during which any number of messages can be exchanged between the customer and the business. Businesses incur charges for each individual conversation, regardless of how many messages are sent or received within that customer service window.

error message for WhatsApp Cloud API test broadcast

Can I delete the Meta test number from my connected Cloud API account?

No, this number is automatically provided to all accounts to use for sending test messages and cannot be deleted. Just be careful to note that this is a test number not to be used for other purposes.

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 uses. This difference causes Contacts from certain countries to be duplicated. Should this occur, do reach out to us here.

  1. Re-register your phone number using the newly approved display name.
  2. Execute a POST API call to verify your phone number.
  3. Make another POST API call to re-register the verified phone number.
  4. Once successful, your Cloud API's display name update is complete.

Why did I encounter the error "Error validating access token: The session has been invalidated because the user changed their password or Facebook has changed the session for security reasons" when trying to send a message?

This error will occur if you have recently updates your Facebook credentials, it may disrupt the Channel connection on our platform, leading to errors when sending messages.

To resolve this issue, you need to refresh the channel permissions on our platform using your updated Facebook credentials. This process requires an Admin role. By refreshing the permissions, you'll re-establish the connection with the new credentials, ensuring that your outbound messages are sent successfully without encountering errors.
