We’ve enhanced Courier’s WhatsApp template configuration with a powerful new capability. You can now directly use Twilio’s Content SID when setting up WhatsApp templates.
Courier now supports Twilio’s Content Template API, enabling users to reference templates by their Content SID. This streamlines integration with Twilio’s latest approach to managing WhatsApp templates, simplifying configuration within Courier.
Instead of manually recreating or reformatting your template data, you can now:
Paste the Content SID from Twilio directly into Courier’s WhatsApp template configuration.
Leverage templates already approved and managed in Twilio.
Reduce friction when updating or maintaining templates.
