I tried to use API in R studio to modify my form. I want to create a numerical field with 2 dp and min of 0. I created a function to do so called create_fields.

create_fields <- function(api_token, form_id, label) {

API URL for adding a field

url <- paste0("https://www.formstack.com/api/v2/form/", form_id, "/field.json")

Payload

payload <- sprintf(
"{"hide_label":false,
"description_callout":false,
"required":false,
"readonly":false,
"hidden":false,
"uniq":false,
"colspan":1,
"sort":null,
"field_type":"number",
"label":"%s",
"decimals":2,
"min_value":0}", label)

API request

response <- VERB("POST", url, body = payload, add_headers('authorization' = paste('Bearer', api_token)), content_type("application/json"), accept("application/json"),encode = "json")

Return the API response

return(cat(response$status_code,"\n",content(response, "text")))
}

I managed to connect to my test form but the numerical field generated just use default attributes (0 dp and no min value) rather than attributes specified in the function.
