Frequently asked questions

Do I need to be a WhatsApp partner to use Chat API?

No. Chat API is a service by Roxpay, which is already an official WhatsApp Business Partner. You connect through our APIs without registering directly with Meta.

Can I embed the WhatsApp chat in my app?

Yes. With a single API call you can generate an iframe URL that embeds the WhatsApp chat directly into your web or mobile application.

What types of messages can I send?

You can send WhatsApp-approved templates (for out-of-window messages) and freetext messages within active 24-hour conversation windows.

Is there a test environment?

Yes. Chat API provides a sandbox environment at sandbox.roxpay.eu where you can test all APIs before going to production.

How does authentication work?

The APIs use JWT Bearer tokens. Generate your token via the /api/v4/auth/token endpoint and include it in the Authorization header of every request.
