When you submit a WhatsApp template for approval through the Twilio Console, you will be prompted to select one of the categories. You will be able to let WhatsApp override the category and approve the template, or let WhatsApp reject the template if the category selection does not match WhatsApp’s classification. Twilio's system will show you whether your selection was accepted or rejected, as well as the final category determined by WhatsApp. Additionally, all templates that were created before the new category-based pricing model took effect on June 1, 2023 have been automatically reclassified by Meta's machine learning classifier.
