Paynow app paymnt intergration

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.
