Gateway Timeout

Understand the SumUp API Gateway Timeout response, common causes, and example payload for upstream timeout failures.

Indicates that the server did not receive a timely response to complete the request. Retry the request, and if timeouts continue, check the SumUp status page(Opens in a new tab) or contact us(Opens in a new tab).

Common Causes

  • An upstream dependency did not respond in time.
  • Network latency or connectivity issues delayed the response.
  • The request required longer processing than the timeout window.
