I'm new to working with the Availity coverages API endpoint and see that there's an error common to the first few calls I've made:
"errorMessage": "Please enter a valid Payer ID.",
I'm using PayerIds taken from a document shared by Availity, so for example Providence Health Plan is listed as having a Payer Id of 101039. Does anyone know why I would get an error rejecting this value? It's throwing this error for everything I've sent, including KSRCN, 040, CHPWA, which all appear as valid Payer Ids in the shared documentation.
