RE: Post a Suilet from button click
I have a button on the item record. When clicked, it should open a suitelet in a new window. I have to pass a JSON object as a parameter to the suitelet. So, when using GET, it fails as the URL exceeds the limit. Can anyone tell me how to call a Suitelet using POST and send the parameters (JSON object) from a button click in the client script.
For making a POST request to a Suitelet, @avivashisth provided a good answer, and that’s the approach I would take.
However, one other option if you’d like a different approach would be saving the JSON to a custom record and passing the internal ID of that record as a URL parameter when making a GET request to the Suitelet. Then the Suitelet could load the custom record by internal ID to load the JSON data.
