Team,

Client has a need for public to be able to pay for license applications online.
CC payment option is supplied by the preferred vendor (don't ask) and we have no control over that; it has it's own web REST api.

Desired actions:

Public user hits anonymous form, applies for license  (amount of fee is tied to license type).
1. Submit form
2. Save to Repo
3. Workflow/WebService call to create cart
4. Show user summary with unique URL to cart payment, such that they can navigate to payment site.

We will take care of confirming payment, etc on the back end, distinct from Forms.

1, 2, 3 are working, it's step 4 that has us stuck.

We have tried creating another workflow that in turn calls a Business Process - but we never get to that step. Or, more to the point, the anonymous submit user just sees the "thank you" and that's it - even though the other steps complete.

Puzzled how the "Workflow show Cart URL" workflow completes, as all it does is invoke a BP who's only purpose is to show the summary link.  So that tells me we're probably attacking this wrong.

Suggestions?
