Nexmo Conversion API
The Conversion API allows you to tell Nexmo about the reliability of your 2FA communications. Sending conversion data back to us means that Nexmo can deliver messages faster and more reliably. The conversion data you send us is confidential: Nexmo does not share it with third parties. In order to identify the carriers who provide the best performance, Nexmo continually tests the routes we use to deliver SMS and voice calls. Using Adaptive Routing™, Nexmo actively reroutes messages through different carrier routes and ensures faster and more reliable delivery for your messages. The route choice is made using millions of real-time conversion data points.
Plan the first integration safely
The access fields below come from the connected directory. Their likely implementation impact is explained without assuming provider-specific behavior.
Authentication
OAuth is reported. Confirm flows, scopes, consent, token lifetime, and refresh rules.
Transport
HTTPS is not confirmed. Do not send credentials or production data until secure transport is verified.
Browser access
CORS is unknown. Treat direct browser access as unconfirmed and test before choosing a client-only architecture.
First-request sequence
- Identify the current base URL, version, and endpoint for the use case.
- Confirm how credentials are issued and where they may be stored.
- Test success, invalid input, throttling, unavailable data, and timeouts.
- Record response fields, pagination, caching, and error shapes.
- Add monitoring, retries with backoff, and an appropriate fallback.
Questions to resolve before production
Pricing and quotas
Confirm current plans, free-tier limits, overages, and request ceilings.
Endpoint coverage
Check that the operations and response fields match the intended workload.
Reliability
Look for uptime history, a status page, support routes, and service commitments.
Data and privacy
Review retention, licensing, regional processing, and compliance requirements.
Versioning
Confirm the active version, change policy, deprecation window, and migration guidance.
Developer experience
Validate SDKs, examples, error formats, pagination, and test environments.
