Over 70% of Ory Network projects involve migrating an existing user base. We've now streamlined the import process to make it easy and fast to import millions of records efficiently:
A new batch API allows to create multiple identities at once with a single
PATCH /identities request or
batchPatchIdentities call from the SDKs. Through this API, you can create up to 1000 Identities in one go, and all Identites will be created as part of a single transaction - which means that they all work or all fail. For performance, the batch API only returns the list of identity IDs created.
