IBM API Connect - Webhooks not configured

I'm learning my way around IBM API Connect at present, which is giving me a great opportunity to also learn IBM DataPower Gateway, which is nice.

Whilst trying to determine why I'm unable to test my APIs on the DataPower Gateway from within the API Manager, I was looking at some of the underlying Developer Portal commands, including: -

list_sites

which returned: -

and: -

which was less than impressive.

Thankfully the Knowledge Centre saved me: -

Installing the Developer Portal

which said, in part: -

So I ran the command: -

download_apim_cert

which returned: -

depth=0 C = US, ST = NY, L = Armonk, O = IBM Corporation, CN = API Connect
verify error:num=18:self signed certificate
verify return:1
depth=0 C = US, ST = NY, L = Armonk, O = IBM Corporation, CN = API Connect
verify return:1
DONE
WARNING: The common name provided in the certificate, "Connect", does not match the configured IBM APIC server: "management.uk.ibm.com".  The developer portal will be configured to trust the provided certificate without checking that the server name matches the common name.
Setting user provided https certificate for portal.uk.ibm.com/davehay/sb

I then re-ran the status command: -

So that's all good then ….
