**Is lack of support preventing you from building workflows, or do you have a workaround?**
I could connect to plutio via a custom action and environment variables, but I'd like a normal auth connection since its more manageable.

**Are there specific actions, or triggers, you'd like to see for this app? Please let us know here or use the Action and Trigger issue templates to open requests for each!**
Since Plutio is a CRM / Project management tool, being able to retrieve and create data would be great.

Actions:
Retrieve/add companies
Retrieve/add businesses
Retrieve/add people
Retrieve/add invoices
Retrieve/add proposal
Retrieve/add projects
Retrieve form responses

Triggers:
To my knowledge, the current API does not support webhooks. However, a source that detects proposal status changes and new projects would be awesome.
