Trigger appsheet from outside to open a form based on a filter/search parameter

[almoonds]

This is the project I’m working on:

Idea:
A new call on a voip pbx arrives, the pbx trigger appsheet to open the form of the customer who is calling with all information

Implementation:
A VOIP PBX at the restaurant receive calls from customers.
The PBX (Vodia PBX) send an “action url” (a HTTP POST) when a new call comes to Telegram Bot with a URL link of appsheet with row information so that when the admin click on the url, appsheet app opens on the mobile with the right form

Problem:
I need to open not an exact row but a filtered row based on the phone number the pbx sends.
Inside appsheet I can use of course linktofilteredrow() function but what about “outside” appsheet?
I would need a “short url” and not something like:

https://www.appsheet.com/start/xxxxxxxxxxxxxxxxxxxxxxx#control=Clienti&filter={"EvalType"%3A"BOOLEAN...

Is there a better or more elegant and clear way to “trigger” appsheet to open a form, view, etc from some app outside?

Maybe I could use Appsheet API to trigger some action/workflow to open the form/view?

Some idea or some workaround? Thanks!
