The InspiringTec API is organized around REST. Every product — WhatsApp, SMS, Email, Voice, Verification, Payments and AI — is accessed through the same base URL, the same authentication header, and predictable JSON responses.

https://api.inspiringtec.com is the base URL for every request.

Authenticate requests by including your API key in the Authorization header. Keys are scoped to sandbox or production and can be rotated from the dashboard at any time.

Authorization: Bearer sk_live_xxxxxxxxxxxxxxxx

Configure a webhook URL per product to receive delivery, verification and payment events in real time. Each payload is signed with a shared secret so you can verify authenticity.

InspiringTec uses conventional HTTP response codes: 2xx for success, 4xx for request errors, 5xx for platform errors. Error responses share one shape:

{
  "error": {
    "code": "invalid_request",
    "message": "The 'to' field is required.",
    "request_id": "req_5c19a0"
  }
}

Requests are rate-limited per API key. Current limit and remaining quota are returned on every response.

HTTP/1.1 200 OK
X-RateLimit-Limit: 600
X-RateLimit-Remaining: 587
X-RateLimit-Reset: 1755331200
