How do I authenticate with the Chatofy REST API?

You authenticate by passing your API Key in the `Authorization: Bearer ` HTTP header on all API requests.

Can I send OTPs and transactional notifications via the API?

Yes! Chatofy provides high-priority OTP and transactional message routing with sub-5-second global delivery times.

Is there a sandbox environment for local development and testing?

Yes. You can use our developer sandbox to simulate message dispatches, test template payloads, and verify webhook responses without incurring live messaging costs.

Where can I find the official API documentation and Postman collection?

Full interactive documentation, OpenAPI 3.0 schemas, and Postman collections are available at `https://app.chatofy.in/docs`.

Do I need an existing WhatsApp Business API account?

No, you can apply and set up your WhatsApp Business API account directly through Chatofy during onboarding.

Can I use my existing WhatsApp number?

Yes, you can migrate an existing WhatsApp number to the API with Chatofy's WhatsApp Coexistence architecture without losing your chat history.

Where can I find the OpenAPI specification for Chatofy?

Chatofy publishes OpenAPI 3.0 specifications at https://chatofy.in/openapi.json and https://chatofy.in/api/openapi.yaml.
