# Create or Update Customer Info

`PUT /customer`

**The Anchor Platform does not persist any customer KYC data.**

The request and response for this endpoint are identical to the
[`PUT /customer`](https://github.com/stellar/stellar-protocol/blob/master/ecosystem/sep-0012.md#customer-put)
request and response defined in SEP-12.

Client applications make requests with the following request body, which is forwarded to the anchor. Anchors
must validate and persist the data passed, and return the customer's `id`. Requests containing only string fields will
be forwarded to the anchor as with the `application/json` content type. Requests containing
binary fields will be forwarded to the anchor as with the `multipart/form-data` content type.
