Everything you need to know about KambaSMS before integrating.
When bulk promotional campaigns share routes with login codes, carriers and inbox providers throttle the queue and delay critical messages. At KambaSMS, our infrastructure is 100% transactional: OTP codes, receipts and operational alerts run on a dedicated fast-lane and never compete with marketing blasts, newsletters or spam.
Timing varies by carrier, network availability and provider. Each accepted request receives a status you can check, and you can test the entire flow for free in Sandbox (kamba_test_ keys). The /otp/send endpoint limits requests to 3 per hour and per number.
Your Sender ID (3 to 11 alphanumeric characters) and message example are reviewed. Track the status in API Keys; once approved, you receive 3 free SMS credits to test in production.
Yes. We provide official SDKs for Node.js, Python, PHP and C# — installable via npm, pip, composer or NuGet — plus a public Postman Collection, Sandbox, API Playground, KambaSMS Desktop and the KambaSMS Connect browser extension.
All accounts include Portuguese/English email support and complete documentation with code examples. For higher-volume operations or dedicated implementation assistance, you can request a custom commercial proposal.
Check the number (+2449XXXXXXXX), balance and history status. Respect request limits before retrying. If it persists, share the X-Request-Id or request ID and timestamp with support — never share the OTP code or your API key.
The proforma and receipts are attached to your top-up request in the dashboard, with monthly PDF and CSV usage export options. If you need a specific tax requirement, confirm with support before paying.
