No Default UA Sent With Requests

[steveamaza]

Sometimes, Cloudflare blocks API requests sent to Paystack servers that have no accompanying User Agent. Setting API requests with any User Agent resolves this.

My favourite UA is Chrome's (for no reason 😀 ) Mozilla/5.0 (Unknown; Linux) AppleWebKit/538.1 (KHTML, like Gecko) Chrome/v1.0.0 Safari/538.1

@steveamaza could that be the reason for this error

Hey guys! Sorry for the late response to this.

UA config was in the code but noticed there was a gap in the logic in how the UA was set. The idea was to allow devs to append custom UAs to the code to further identify where the request is coming from. I have simplified it now so UA is always to set to something like paystack-go/$CURRENT_LIB_VERSION. See https://github.com/rpip/paystack-go/blob/master/paystack.go#L29

Updated the UA to use the Mozilla UA @steveamaza suggested, but the build is still failing.

Won't be able to look into this again anytime soon. Happy to give access to anyone interested in helping maintain the lib. Thanks!

Hi @steveamaza, actually, it's the transfer test that's failing. The error response from Paystack doesn't indicate why.
