Hello,

i want to call a numeric value from an api i created and assign it somewhere or compare it to other values. is this possible in pdf?

What is the interface to your web API? POST? SOAP? HTTP submit? Something else?

Will users expect to use this from a web browser such as Chrome or Edge? From a mobile device? Or just from Acrobat Pro? Or do you expect it to work with the free Acrobat Reader?

i wanted to build a simple http api, a simple get returning e.g. a number.

users should be using it in adobe reader dc. i am trying to implement it in adobe pro 2017.

The most reliable method would be to set up the submit action so it submits to the web server at "HTML Form". To return a value to the form, the server would generate an FDF that includes the field name/value pair. When the response from the server is received by Reader, the field will be populated by the value in the FDF. This can work with a PDF viewed with Chrome's built-in PDF viewer as well.

This is actually working, thank you very much!

In the end its very important to take a good look at the format of everything i guess, but i am able to get information from my webserver into my pdf.
