Paynow app paymnt intergration

#1

Hi Paynow team,

I’m integrating Paynow EcoCash payments for my app using the initiatetransaction endpoint.

I’m getting “Invalid Hash” errors. Can you please confirm the exact field order for the SHA-512 hash calculation for initiatetransaction?

I’m currently trying:
id + reference + amount + additionalinfo + returnurl + resulturl + authemail + phone + status + integrationKey

But Paynow keeps expecting different hashes.

Please provide the exact hash field order including all required fields.

Thanks,

I don’t think order is the issue, check if you are using the correct authemail and phone if you are still in development.
