One message.
Build a clear phone verification experience for your users. Explore SMS integration for sign-up, account access and recovery.
Define your flow
Connect each verification request to a user, a phone number and a specific action.
Integrate on the server
Keep API credentials out of client applications. Handle timeouts and retries deliberately.
Verify the result
Apply expiration, attempt limits and single use on your server. Track delivery and verification separately.
A clear starting point.
Does the website demo send real SMS?
No. The demo runs in your browser and does not require a phone number or create an account.
How do I get current pricing?
Contact destek@teksms.com with your expected message volume, destination countries and integration requirements. Pricing and activation terms are confirmed as part of your quote.
Are the code examples a production API reference?
The examples are integration templates. API endpoints, authentication and payload fields must be matched to the current service contract before use.
Is SMS suitable for every authentication use case?
SMS has limitations including SIM swap and phishing risks. Higher risk applications should evaluate additional or phishing-resistant authentication methods.
