Sharing app credentials with IPaas provider

[jag3]

I had a query regarding using IPaaS providers such as Tray.io, Workato, etc.

For a desired user experience, I'd want to provide as minimal friction as possible, and programatically pass OAuth details of our clients to the IPaaS provider using a delegate access token. However, in order for this process to work, we might have to provide them with our Shopify app credentials.

My question is, would sharing the app credentials be in violation of the Shopify API License and Terms of Use, even though the IPaaS provider would be acting on our behalf?
