One platform for WhatsApp, SMS and Email
Chat API provides APIs to send notifications and manage communications via WhatsApp, SMS and email. Choose the right channel for every need.
Chat API: the messaging infrastructure for your business
Chat API is a platform developed by Roxpay that provides unified APIs for WhatsApp Business, SMS and email. With a single integration you can manage all your company's messaging channels via simple, well-documented RESTful API calls, without having to build a sending infrastructure from scratch.
Unlike traditional enterprise solutions, Chat API is designed to be activated completely on your own in minutes: no lengthy onboarding process, no commercial negotiations. You create an account, generate API credentials and start sending messages directly from your application. The free sandbox plan lets you test every endpoint before going to production.
The entire infrastructure is hosted in Europe and fully complies with GDPR — a priority for European companies handling their customers' personal data. We offer the possibility to sign a DPA (Data Processing Agreement) to fulfil the obligations of the European Data Protection Regulation.

Frequently asked questions about Chat API features
Can I use Chat API without a dedicated WhatsApp Business number?
No. To access the WhatsApp Business API, you need a dedicated phone number registered through Meta Business Manager. Chat API guides you through the entire activation process, which is fully self-service and typically takes 24–48 hours from business verification.
Is it possible to integrate multiple channels with a single authentication?
Yes. Chat API uses a shared JWT authentication system across all channels. With a single token you can send WhatsApp messages, SMS and emails, drastically reducing integration and maintenance complexity.
How much does Chat API cost?
Costs vary by channel. For WhatsApp, Meta's per-conversation pricing applies (starting from €0.058 per service conversation in Europe), plus the Chat API plan. For SMS and email, prices depend on volume. See the pricing page.
Is Chat API GDPR compliant?
Yes. The entire infrastructure is hosted in Europe and data is never shared with third parties. Chat API offers the option to sign a Data Processing Agreement (DPA) to fulfil GDPR obligations for companies handling European customers' personal data.
Can I send marketing messages on WhatsApp?
Yes, within Meta's policies. To send promotional messages on WhatsApp, the recipient must have explicitly consented to receive commercial communications. Chat API provides tools to manage contacts and consent, so your campaigns always comply with platform rules.
