This tutorial explains how to retrieve data that people entered by filling out and signing your forms using our eSignature API.
You can only retrieve data entered by signers in some fields. You also need a way identify the fields you add to your form, otherwise you won’t be able determine what data was entered in which particular field.
We offer a way to specify identifiers for your fields while sending out a signature request, and later retrieve all the data that signers have entered in these fields. This data will come with the field identifiers that you specified, so you will know what data has been entered in which field.
To identify your fields, for each of them you would need to specify the api_id parameter. The value for this parameter can be any non-empty string.
It makes sense to select unique api_ids for your fields within each signature request (though it is not a requirement), otherwise you won’t be able to differentiate between different fields later.
