How to create a signature invite using the signNow API?
You can send both Freeform and Role-Based signature invites to recipients.- For Freeform invites, you will need the POST document/@{{document_id}}/invite endpoint. Mind that the document_id, in this case, will belong to a document without fillable fields.
- To send a Role-Based invite, use the same endpoint for a document with fillable fields.
-
How to cancel a signature invite sent via the signNow API?
Signature invites can be canceled before recipients sign a document. To cancel an invite, use the PUT document/@{{document_id}}fieldinvitecancel endpoint. If some recipient(s) have already signed the document, their signature(s) will remain. The other signers will not have an opportunity to open the document. -
What’s the difference between freeform and role-based invites?
Freeform invites allow recipients to place their data and signatures anywhere on documents you’ve sent. Send a freeform invite if the location of the recipient\'s content in a document is not really important. With a role-based invite, signers have to fill out and sign certain fields in a pre-set order. Find more details here. -
Can I send signature requests in bulk?
Of course. Upload a document, turn it into a template, and add fillable fields. You’ll need to have a CSV file with a list of email addresses to send your template. Indicate a folder to store signed documents. Use the endpoint POST /template/@{{document_id}}/bulkinvite where @{{doument_id}} is the id of the template for sending bulk invites. -
