Validate the v3 request signature HUBSPOT using PHP
I am trying to connect a Hubspot CRM with my internal application, to send values from Hubspot to my app using Webhooks, with Authentication: Hubspot app id. But the HTTP_X_HUBSPOT_SIGNATURE_V3 does not match my hashed string.
But I understand that the secret key that the client gave me and starts with 'pat-eu1' in not the right key, 'The secret keys the documentation is referring to are developer apps where you are given a client ID and client secret key.'.
I will ask for the proper key and I will try again.
