Hello. I have been using PayPal through the SDK to create invoices for user payments for the past 4 years.
Recently (two days ago), when creating invoices, your service started returning the following response:
The response from https://api-m.paypal.com/v2/invoicing/invoices comes back as CREATED as expected, but the subsequent request to https://api.paypal.com/v2/invoicing/invoices/link_href/send returns an error.
422 Unknown Error
{"name":"UNPROCESSABLE_ENTITY","message":"The requested action could not be performed, semantically incorrect, or failed business validation.","debug_id":"***","details":[{"field":"step_up_context","value":"***","issue":"AUTH_FLOW_REQUIRED"}],"links":[{"href":"https://developer.paypal.com/docs/api/invoicing/#errors","method":"GET"}]}
I couldn't find any information regarding AUTH_FLOW_REQUIRED. My country is appropriate, and payments were working fine.
