LTI 1.3 Deep Linking issues


Hello. I am with Pivot Interactives (, a science education supplement, and we are trying to create an LTI 1.3 app with Deep Linking and Grade Services within schoology. We've successfully integrated with other platforms using LTI 1.3.

When configuring the app, I'm not seeing the deep linking launch at all when creating the external tool from Add Materials > External Tool. In other platforms when doing this, an iframe opens to our site, initiating deep linking, then closes and populates the URL once the user is done making the appropriate selections on our site within the iframe.

Instead, the tool is created, and when I click the tool, our platform throws an "assignment is required" error, which is expected since I wasn't ever able to select an assignment on our site to link to. I'm also getting a 400 error at the final launch request after a successful connect and authorize-redirect, again which makes sense.

Any help you can provide would be greatly appreciated!
