We are creating a Sythetic API Monitoring. We have client certificate(.p12 file) to access the API. Can you help me how to use this certificate to authenticate API and monitor it.
That’s a tough one! I don’t know of any examples where this has been done in the past, but, that doesn’t mean it’s impossible.
Pulling in your cert to the script may be a challenge, but I think if you can host that certificate in a gist, or online elsewhere, you can do similar to the example: Feature Idea: Referencing common script functions
From there you may be able to use an example similar to this to send your p12 format cert.
