# Error code when sending a WhatsApp Template Message via API

Are you trying to send a Template Message via API but you're receiving an error back? There are a few things you can check before sending a Template Message to avoid errors: 

* **You're using the correct API key.** Make sure that you're using a live key. 
* **You're sending along a Namespace ID.** This information is usually shared once your WhatsApp channel has been created. If you do not have this information, please contact support. 
* **Template Messages should be approved.** Go to your [WhatsApp template manager](https://dashboard.messagebird.com/en/whatsapp-template-manager/) and see if the Template Message has been approved. 
* **There's no error in the template name.** Go to your [WhatsApp template manager](https://dashboard.messagebird.com/en/whatsapp-template-manager/) to see which name was set up. 
* **The language matches the Template Message.** 
* **All parameters are completed.** If you register a message with 3 variables, make sure to add 3 variables in your API request as well. 

If after checking this the issue still persists, please reach out to our Support team via [this page](https://www.messagebird.com/contact)  with your API call and API request[.](mailto:support@message.com)
