# Should I migrate to the access.tryterra.co endpoint?

If you received the migration email, **switch REST requests to the new base URL `https://access.tryterra.co/api/v2`.**

A few things to know:

* The old URL still responds because the migration is phased and both endpoints temporarily coexist.
* The new API is **fully backwards compatible** and requires no code changes.
* The official SDKs are being updated to use the new endpoint automatically; update to the latest SDK version when available.

Migrating also resolves `500`s on historical fetches for older dates and gives you longer payload-detail retention going forward, since extended look-back is only supported on the new endpoint.
