Sometimes it's desirable to pre-fill Filedrop information. For instance, you may want users to always fill in certain information when they visit a Filedrop. Consider the following Filedrop:

images/general/filedrop_prefill.png

In this case, you have two questions you want everyone that visits this Filedrop to answer. This can be pre-filled by appending the following on the URL:

/filedrop/test?message=Question%201:%20%0AQuestion%202:

This is obviously something that you want to link to from another page. It also needs to be URL encoded, so %20 is space and %0A is newline.

You can use this to prefill the following parameters:

A more in-depth example would then be:

/filedrop/test?message=Question%201:%20%0AQuestion%202:&from=user@company.com&subject=some%20test%20subject
