Send an approved template and get it on your phone
The Messaging API sends WhatsApp templates approved by Meta. Pick one of our example templates: text with variables, image, video or document headers, reply, link and copy-code buttons. Every change rewrites the request.
Choose a template to see its fields, the request and the preview.

Frequently asked questions
Quick answers about the Spellty Messaging API.
What is the Spellty Messaging API?
The Spellty Messaging API lets your systems send WhatsApp template messages: confirmations, reminders and notifications. You authenticate, choose the template and the recipient, and Spellty sends it.
What can a message include?
Templates can carry text, an image, a document or a video in the header, the body and the footer, and buttons.
Can I send a message to a group of contacts?
Yes. You can create groups, list their members and send a message to a group through the API.
How do I know a message arrived?
Set a webhook and Spellty notifies your application of the events of each message: dispatched, sent, delivered, read and failed.
Is there a Postman collection?
Yes. Spellty publishes a Postman collection with the authentication and the sending of templates that you can clone. The live try-out on this page also sends a real message to your WhatsApp.
How much does it cost?
Plans are priced by the messages they include each month; see the pricing page. The fees of WhatsApp are billed to you by Meta, with no markup from Spellty. The first 7 days are free, with no credit card.
