I'm created a connected app in salesforce and consume contacts in my application, but for this, a need a consumer key from connected app.
I would like to create an application that consumes my customers' contacts without them having to create a connected app and generate a consumer key, in order to access their list
I saw this in a hubspot integration in salesforce, where it was possible to install a hubspot package and consume the contacts, I tried to create something on the appExchange but I was unsuccessful. Can anyone tell me a tutorial for this? I've been searching for days and I can't find anything.
