You must provide a display name when registering a business phone number. The display name appears in your business phone number’s WhatsApp profile:
It can also appear at the top of individual chat threads and the chat list if your business phone number is approved via display name verification. Note that if a WhatsApp user edits your profile name in the WhatsApp client, the name they set will appear instead.
If your display name is approved, the webhook has decision set to APPROVED, and the name_status field on your business phone number is set to APPROVED.
Your business phone number’s display name appears in the Name column in the WhatsApp Manager > Account tools > Phone numbers panel.
Get display name and display name status via API
Request the verified_name and name_status field on your WhatsApp Business Phone Number ID to get its display name and display name status. See the WhatsApp Business Phone Number API reference for a list of returnable values and their meanings.
The verified_name value doesn’t indicate whether the display name is approved. It represents the display name string that undergoes verification when eligible. The name_status field indicates its approval status.
You can change a display name 10 times per 30-day period. After the display name change is approved, you have 14 days to re-register the phone number. If the 14-day window expires without re-registration, you must submit the display name for review again.

Example response
Upon success:
{
"success": true
}
Upon success, your display name undergoes display name verification. To check the verification status, request the new_display_name and new_name_status fields on your business phone number ID:
{
"new_display_name": "New Lucky Shrub",
"new_name_status": "PENDING_REVIEW",
"id": "106540352242922"
}
When your updated display name is approved, your business phone number’s verified_name and name_status fields update to reflect your new display name and name status, and phone_number_name_update webhooks are triggered. You must then re-register the phone number. Re-registering before approval has no effect.
Re-register after display name approval
After updating your display name via WhatsApp Manager or API, you must re-register your phone number to solidify the new display name with WhatsApp servers.
