Frequently Asked Questions about LSO Sonata API

API onboarding, integration and usage

What is required to implement the Sonata API?

The service is available to Telia Wholesale customers. Implementation requires access to the API Developer Portal, API keys, and development in the customer’s own system.

How long does integration take?

Typically, implementation takes from a few weeks to a few months, depending on the scope of the customer’s development work.

Is a test environment available?

Yes. APIs are available in a test environment and sandbox before moving to production.

Are example integrations available?

Yes. Telia provides developer support materials, such as sample messages and a Postman Collection.

Can the API be used in multiple countries?

Yes. The same API supports automated responses to addresses in Finland and Sweden.

Availability and quotes

What does the POQ response mean in practice?

A POQ response indicates whether the service is available and provides an estimated delivery time.

Is a quote always available instantly via the API?

Not always. For automatically handled locations, quotes are immediate, but some cases require manual processing.

Why is not all availability automated?

Infrastructure is not ready at all locations. In such cases, availability or quoting requires separate analysis by network specialists.

Ordering and delivery

How can order progress be tracked?

Order progress can be tracked via the API by registering your system to receive State Change and Milestone notifications, as well as querying status data. Orders can also be tracked manually in the Wholesale ordering and delivery system if needed.

Can orders be placed without the API?

Yes. API-generated quotes can be converted into orders in the Wholesale ordering and delivery system. The API complements the system – it does not replace it.
