# Add a customer address

POST `/partners/customers/{uuid}/addresses`

Adds an address to a customer.

Every field is optional individually, but the body must carry at least one of `street`, `city`, or `zipCode` — an address with none of those is rejected. Setting `isPrimary` demotes the customer’s current primary address.

HMAC signature + Bearer access token
