Send error signals with the API

Send an error signal to Connect with the createSignals mutation. For authentication, contact mapping, consent and the response, see Send signals with the API (GraphQL).

To learn what this signal captures and how to use it in Connect, see Application error signal guide. To send it from your website or app instead, use Log signal: web, Android, iOS.

Sent when a user encounters an error on your site. Focus on payment, promo code, and account registration errors that lead users away from the happy path.
