How to register data from user interface to integration object

Would you please describe in a bit more detail what you want to achieve.

Did you already attended the trainings in the academy and tutorials in the documentation?

Thank for reply

Sorry for the lack of information.

Now I implemented API.

I have completed the connection system, integration, and implementation of web api.
So,i try to register a value from the interface.
After clicking the button, the value from the interface is passed and integration object is received by parameter of rule input.
I couldn't pass the value of interface as a parameter.....

An integration is called like any other expression object. Can you share some code snippets?

docs.appian.com/.../Integration_Tutorial.html

HERE MY CODE 

OK, thanks.

What is the purpose of this? Write the entered data to DB? Is there a reason to not go the normal Appian way and trigger a process?

The a!save() is pretty pointless as it stores the value into itself.

The integration seems to be valid. Where is it called in the interface?

The purpose is want to writing to db.
I wonder if it didn't work because integration wasn't called from the screen
and need to use process ？

Depending on which technologies you have experience with, Appian will take a bit to wrap your head around.

I highly recommend to check out the trainings in the Appian Academy and the tutorials in the Appian documentation.

I also just published my book about low-code with Appian which might help you as well.

Thank you for your advice I will read the link again your shared earlier .
