Updating Identities

Mutations can be used to update the email identities in Nosto. An "identity" is the personal information associated with an email address.

Upserting Identities

The upsertIdentity mutation allows you to upsert the details of an identity. The given example updates the customer attributes for the email john.doe@nosto.com and requests the details of all the attributes of the identity.

If the identity for john.doe@nosto.com does not exist, a new identity will be created.

Note: If a specified attribute already exists on that identity, it will be overwritten.

curl -0 -v -X POST https://api.nosto.com/v1/graphql \
-u ":<token>" \
-H 'Content-Type: application/graphql' \
-d @- << EOF
mutation {
  upsertIdentity(identity: {
    email: "john.doe@nosto.com",
    attributes: [
      {name: "loyalty-tier", value: "Gold"},
      {name: "shoe-size", value: "42"},
  }) {
    attributes {

What can identity attributes be used for?

The attributes associated with an identity can be used to segment users. This works similarly to how the attributes can be leveraged when importing them via a CSV.

Deleting Identities

There is currently no way to delete an identity.
