After that, the document is sent to Skribble platform: - If the action is set to `seal` : The document is sent to Skribble and when sealed, the sealed document URL is given back in the result as per below: ```xml 0 DigitalSigningCOA.Skribble https://api.skribble.com/v1/documents/88de7466-d50c-b171-3feb-f1374e02695c/content OK ``` - If the action is set to `signature` : The document is sent to Skribble and as it is signed per each signer, the `callbackUpdate` and `callbackSuccess` are used to manage the document lifecycle. When succeeded, the whole signed document can be retrieved based on the information available in the callback. - If the action is set to `seal+signature` : The document is sent to Skribble and when sealed, the sealed document URL is given back in the result. In the same time frame, the sealed document is sent to Skribble and as it is signed per each signer, the `callbackUpdate` and `callbackSuccess` are used to manage the document lifecycle. When succeeded, the whole signed document can be retrieved based on the information available in the callback ## Result The seal and the signature places are visible through a thin line rectangle.
