SMS Gateway API Basics

An SMS gateway API exposes a set of RESTful endpoints that let applications programmatically send and receive SMS. On Android, you can either call a cloud‑based API or use the device itself as a gateway through specialized apps.

2. Obtain API Credentials

1. Sign up on the provider’s portal.
2. Navigate to the “API” or “Credentials” section.
3. Generate an API key (and secret if required) and store it securely (e.g., Android Keystore).

Tip: Use environment variables or encrypted secrets in your Android project to avoid hard‑coding keys.

FAQ

Can I use the same API key for both Android and cloud endpoints?

Yes, but it’s best practice to generate separate keys or scopes for each environment to limit exposure.

Is two‑way SMS supported on all providers?

Most major providers (e.g., Infobip, TextMagic) support inbound messages via webhooks. Verify the feature in the provider’s documentation.

How do I stay compliant with GDPR or local regulations?

Maintain explicit opt‑in records, provide easy opt‑out mechanisms, and store consent data within your CRM.

What’s the cost difference between a cloud API and a local Android gateway?

Local gateways incur carrier rates and possibly app licensing fees but eliminate per‑message API fees. Cloud APIs typically charge per message sent/received.

Can I integrate SMS with other channels like email or push notifications?

Absolutely. Most CRMs allow multi‑channel workflows, enabling you to trigger email, push, or SMS based on the same event.
