Integration updates

There have been some improvements made to the custom integration builder.

1. You can now add default values to your integrations so when the action is added to a journey the value is already set
2. You can now manage what fields are shown on the action in the journey builder so if you have a large endpoint with a lot of fields that are needed, you can simply hide those fields from the user working with the action in the journey builder. Simp

Additionally we changed the way you test your endpoints which are now performed in a modal where you first configure your test values and then secondly view the response.

​Why did we make this improvement?

• A lot of third party software require input values that are always the same and the user creating the journey has no knowledge of what value are required so the default value feature helps with that
• Being able to manage what data is shown in the journey builder for the integration action will make the experience for the user a lot more straightforward as they only see relevant fields for the action
