The **public-key-missing error** occurs when the client cannot retrieve the business’s public key from WhatsApp servers. This issue prevents secure communication and can disrupt WhatsApp Flows.

## What Causes public-key-missing?

The error typically happens due to:

1. **Missing or Incorrect Flow Public Key –** The required public key is not uploaded or linked correctly.

2. **Configuration Issues –** The phone number used for sending Flows is not associated with the correct public key.

3. **WhatsApp Server Issues –** Temporary server problems may prevent key retrieval.


## How to Fix the public-key-missing Error

Follow these steps to resolve the issue:

### 1\. Verify Public Key Upload

Go to [Meta Business Manager](https://www.heltar.com/blogs/how-to-access-whatsapp-manager-on-meta-business-manager-cm58dt4sr001sx9tqqhi8rmgo) and ensure the correct Flow public key is uploaded. Confirm that the key is linked to the phone number used for sending Flows.

### 2\. Check Phone Number Configuration

Ensure the phone number registered with the WhatsApp Business Account is correctly configured. If using multiple numbers, verify that each has the correct public key assigned.

### 3\. Retry and Debug

If the issue persists, retry sending the Flow after some time. Check API logs for any additional error messages that may provide more details.

### 4\. Contact WhatsApp Support
