Fair enough, I figured you might piece together the details but I probably should have just connected the remaining dots. When moving between a page workflow and a backend workflow you must pass all of the data you are going to need from the page workflow to the backend workflow via additional parameters.
On the page workflow you will be able to get data from the inputs. See below:
datafield1 and datafield2 are now available in the “Make changes to a thing…” because they are passed in via workflow parameters:
Workflow additional parameters:
Workflow additional parameters on the “Schedule API Workflow on a list…”
Example of passing inputs from the page (ddlDay/ddlMonth/ddlYear) into the API workflow parameters defined above.
This connects all of the dots. If this doesn’t make sense to you I would suggest reviewing the documentation further or watching a few videos on Bubble workflows.
