Thank you for your post, and I apologize for the late reply.
FileMaker Go does not have the ability to execute a SOAP based service. In FileMaker Pro, when you go into Manage Scripts, if you modify an existing script (or create a new script), the bottom left corner has a pop-up for "Show Compatibility". Change this from "Desktop" to "iOS", and you will see the available commands. Notably greyed out are "Execute SQL" and "Send Event".
I recommend you enter this suggestion into our Feature Requests web form at:
The entries into this web form populate a database file hosted by Development and Product Management, where these entries are discussed and considered for a future release. Although I could copy your post and paste it into the web form, there are a couple of questions asked that only you can answer.
Has this feature come about? I'm just getting started with FMPAdvanced and FMGo and it would be great if a db on ios could make a call to my web service.
This feature is not available in the latest release of FileMaker Go (14.0.3).
