If a payment, delivery or invoicing integration stops working, first check the error message and the external service’s status. Confirm that the API address is correct, your credentials are valid and you are using the right environment: test or production.

Do not disable certificate verification to force a connection. When asking for help, share the error time and relevant message without including passwords, API keys or personal data.
