This page explains the different statuses for templates.
Each WhatsApp template requires approval from Meta. So, whenever a new Template is applied, it goes into Pending status and later is either Approved or Rejected.
Pending
When you submit a new WhatsApp Template, it goes into status.
It's important to understand that the template approval process is automated by Facebook and may take up to 2 days. In some cases, it might take even longer.
Unfortunately, we don't have any control over the speed of approval or the reasons for rejections.

After your template has been , you are then able to:
Schedule broadcasts
Set up automated drip campaigns

Use of URL shorteners (bit.ly, tinyurl, goo.gl, etc.)
Messages containing misspellings or grammatical errors.
Inclusion of dummy values in samples
Template message content not matching the selected language or category.
