Clearing JSON-String

Hi,

I′m using the PRO Version to connect an Elementor Pro Form to an external API.
With POST Method an JSON-String as Results Format.
In the BODY I left the name-Field blank and inserted a JSON description in the value field like
{“field_1″:”value_1”, “field_2″:”value_2”, etc }.
Encode Body I set to No encoding (raw).
Now the BODY I get in the Action_Log gives me:
“”{“field_1″:”value_1”, “field_2″:”value_2″, etc }”” with two quotation marks in the beginning and the end.
This is not accepted by my API.
How can I get rid of these?
Thx for putting me on the right track!
Yours, Frank
