Telnyx API /LRN* endpoint removal

Deprecated, no dateSubscribe to Telnyx APIShare

Telnyx deprecated the legacy /LRN* endpoints without a shutdown date. Calls to these paths will eventually fail, as they predate the current V2 REST API and are retired from use in new integrations.

Calls it hits

/LRN*

What to use instead of these calls

Look up a number's carrier and routing with GET /v2/number_lookup/{phone_number}?type=carrier instead. Moving takes more than changing an identifier, as there is no direct one-to-one replacement and the matching V2 product must be chosen and validated.

Telnyx names no one-to-one replacement for its retired HTTP APIs: the matching V2 product must be chosen and validated.

In Telnyx API's words

Retired HTTP API inventory Do not use these HTTP endpoints for new integrations The endpoints below predate the current V2 REST API.
