Create JSON to send API request in R

This might have been asked and solved before, I just can't get a straightforward answer.

I got the following:

text <- 'Testing to be translated'

Which I am trying to get into JSON format like:

[{"Text": "Testing to be translated"}]

I have tried using toJSON but I could not get that structure. Additionally, I did some quick-fix:

paste0('[{"Text":"', text, '"}]')

Which would work fine; however, I have some strings with the " and ' characters in it and they would break this code.

Any input would be helpful. More context: I am using a GET request to translate text from Azure server, could not use translateR so I am creating my own function.

To create an array, pass jsonlite::toJSON an unnamed list or vector. You should also set auto_unbox=TRUE so that scalars aren't treated as arrays.

text <- 'Testing to be translated'
jsonlite::toJSON(list(list(Text=text)), auto_unbox=TRUE)

# [{"Text":"Testing to be translated"}]
