getShopifyCustomerId()

getShopifyCustomerId(): number | null

Returns the Shopify customer ID from the current token.

Returns​

number | null

The Shopify customer ID if authenticated, or null if not authenticated or token is invalid.

Remark​

Use this method to check if a customer is already authenticated before calling setToken(). This helps avoid unnecessary token overwrites in storage.

Example​

window.gw.sdk.runIfModuleReady(
  window.gw.sdk.common.constants.modules.AUTHENTICATION,
  () => {
    const currentCustomerId = window.gw.sdk.authentication.methods.getShopifyCustomerId();
    if (currentCustomerId !== newCustomerId) {
      window.gw.sdk.authentication.methods.setToken(token);
    }
  }
);
