Are you struggling with an alternative to your URL Hack custom buttons? Don't know Apex and can't get a Lightning Component created as Salesforce suggests?
I was until @Jenea Johnson suggested trying a Flow! I did this and it allowed allowed me to recreate my URL hack button and even add some additional features!!
Here is my use case - I have a button on the Opportunity record that creates a new custom record and defaults known information from the related Opportunity and Account records to this new record. I have about 30 fields of known information that get defaulted.
Now I have never created a flow before so I needed to learn how to make this all come together.
Jenea gave me the links to the Flow Trailhead modules and I worked them side by side to get started with my flow. Jenea helped me fill in some blanks and low and behold it works!!
I worked through the Build a Discount Calculator project on Trailhead and that gave me enough information to start working on my own - https://trailhead.salesforce.com/projects/flow_calculate
The last module on this project shows how to create a custom button to activate the flow.
Now it works like my URL hack button but even better!!
