Submit a document for signing with specifing location of graphical representation of signarure

If you want to specify locatation of graphical representation of signature you have to set graphicalRepresentationType to CUSTOM. And specify values of top, left, page. You can see example on image below.

Example request body.

{
  "signeesUsers": [
    {
      "signeeEmail": "[email protected]",
      "signeePhone": "+48XXXXXXXXX",
      "signingOrder": 1,
      "name": "Imię",
      "surname": "Nazwisko",
      "skipAccountCreation": false,
      "signature": {
        "top": 100,  
        "left": 100, 
        "page": 2 
      }
    }
  ],
  "title": "title",
  "signeeSignatureType": "EASY",
  "graphicalRepresentationType": "CUSTOM",
  "skipAccountCreation": false
}

A single „rectangle” with a signature measures Width: 160px Height: 36px

Maximum position of A4 signature placement vertically: Max top = 807px Max left = 435px

Maximum position of A4 signature placement horizontal: Max top = 560px Max left = 682px

WARNING!! On one vertical A4 sheet you can fit 3 signatures (on one level). To center them perfectly, set the coordinates according to image below.

Callbacks

Document signing status change notification

POST http://yourserver.com/

Successfully implementing signing process with Signius requires client to take care of document status change notifications. The url for callback notification has to be configured beforehand on the client’s account. Depending on the configuration the callback notification can be sent either after placing last signature on a document (a good time to download fully signed file), or after every signature placed on the document (when you may want to notify next signee about awaiting signature

Request Body

Name	Type	Description
documentId	string <uuid>
presentSignee	string <uuid>
nextSignee	string or null <uuid>
documentStatus	string	The value should be "SIGNED" or "SIGNING_IN_PROGESS"

200: OK Return this code if the callback was received and processed successfully.

500: Internal Server Error default The callback will be repeated 5 times - each retry after an hour.
