# Send Template Message
> Send an approved WhatsApp message template to a phone number via the ChatSyncs API — generated end-to-end from the API Developer Console, no hand-written fields. Use when a developer asks how to message someone outside the 24-hour window, or how to send a specific template programmatically.
Sends an approved [WhatsApp template](/learn/whatsapp-message-templates) to a phone number —
the way to message someone **outside** the 24-hour session window, where
[Send Text Message](/developer-api/whatsapp/send-text-message) won't work.
**You can't send a template message from this page.** Every template needs different fields —
one might just need a name and phone number, another needs a checkout link, a price, or a
button URL — so there's no single request that works for all of them, and the Playground below
can't test one either. Follow the steps below to generate and run your exact request from the
**[API Developer Console](https://platform.chatsyncs.com/api/developer/console)** instead.
## Generate the request
You never need to guess `template_id`, variable names, or field formats — the console builds
the whole request for you, already filled in. The only thing you type at the end is the
recipient's phone number.
Go to the **[API Developer Console](https://platform.chatsyncs.com/api/developer/console)**
and click **Send Text Message** in the sidebar. The template generator lives further down
on this same page — it isn't under Chatbot Manager.
Scroll down to **Generate API End-point: Send Template Message**, choose the WhatsApp
account to send from, then click the approved template you want to send.
A popup lists every variable the template needs — none of them come pre-filled. Type a real
value into each one: a product list, a price, a checkout link, a button URL, whatever that
specific template calls for.
The console generates the exact GET URL and POST curl for that template — `apiToken`,
`phone_number_id`, `template_id`, and every variable you just typed are already filled in.
The only placeholder left in either request is `phone_number`.
Copy the POST curl (or the GET URL) out of that popup — `apiToken`, `phone_number_id`,
`template_id`, and every variable are already inside it, so there's nothing left to look up.
Replace `phone_number` with the recipient's number (country code first, digits only, no `+`,
e.g. `91XXXXXXXXXX` for an Indian number), then run it from a terminal or a tool like
[Postman](https://www.postman.com/) or [Insomnia](https://insomnia.rest/).
