Every field has a unique ID that can be used to identify the field and auto-fill it with pre-set values.
For example; to auto-fill a "short text" field with the value "Plutio":
Copy the form's URL/Link, for example: https://app.plutio.com/p/form/formID?
Paste the unique field ID that you wish to auto-fill just after the "?" sign as follows: https://app.plutio.com/p/form/formID?fieldId=
Now enter the value that you wish to be auto-filled just after the "=" sign as follows:
The final URL will now look something similar to:
Where yellow is the actual form URL/Link, orange is the ID of the field you wish to auto-fill and green is the value to be auto filled into that field.
You can auto-fill more than one field by repeating the process on the same URL but adding "&" between each of them.
For example; https://app.plutio.com/p/form/formID?fieldId1=Plutio&fieldId2=HI
