PDF Electronic Seal API
API Parameters
Signature Format (signatureFormat)
Specifies a supported digital signature format:
- PADES : This is the latest and improved signature format which is more strict, concrete, and secure. For details, see ISO 32000-2 and ETSI EN 319 142-1.
- PKCS7 : This signature format is less stringent than PADES since it permits more PDF changes without invalidating the digital signature. This is the default signature format. For details, see ISO 32000-1.
Document Level Permission (documentLevelPermission)
Specifies the DocMDP (i.e. Document Modification Detection and Prevention) permissions. These permissions are applied to the output electronically sealed document.
- NO_CHANGES_ALLOWED : No changes to the document are permitted. Any change to the document will invalidate the signature.
- FORM_FILLING : Allowed changes are filling in forms, instantiating page templates, and performing approval signatures. This is also the default document level permission, if not specified by the user.
- FORM_FILLING_AND_ANNOTATIONS : In addition to above, annotation creation, deletion, and modification are also allowed.
Long Term Validation (LTV) information of Timestamp Certificates (if using Trusted Timestamping) is embedded in the PDF document only if Document Level Permission is set as FORM_FILLING or FORM_FILLING_AND_ANNOTATIONS.
TSP Credential Information (cscCredentialOptions) : Required
TSP parameters encapsulate the sealer's certificate credential as well as the associated authentication and authorization data.
TSP Name (providerName) : Required : Specifies the name of the Trust Service Provider used to generate the certificate. Presently, only TSPs supporting the OAuth 2.0 client credential authorization flow are supported. The table below provides the provider name mapping for each supported Trust Service Provider.
TSP Credential Id (credentialId) : Required : Specifies the Digital ID stored with the TSP that should be used for sealing.
TSP Authorization Context (authorizationContext) : Required : Encapsulates the authorization data required to communicate with the TSPs.
- Access Token (accessToken) : Required : Specifies the access token used to authorize access to the CSC provider hosted APIs.
- Token Type (tokenType): Specifies the type of access token. Default value is "Bearer".
TSP Credential Authorization Parameter (credentialAuthParameters) : Required : Encapsulates the credential authorization information required to authorize access to their digital certificate.
- PIN (pin) : Required : Specifies the PIN associated with TSP provided credential ID.
TSA Information (tsaOptions) :
TSA parameters encapsulate the timestamping URL and credentials.
TSA URL (url) : Required : Specifies the TSA URL to be used for getting timestamp token.
TSA Credential Authorization Parameter (credentialAuthParameters) : Encapsulates the credential information required to authenticate the TSA URL.
- TSA Username (username) : Specify the username for authenticating TSA URL.
- TSA Password (password) : Specify the password for authenticating TSA URL.
Seal Field Parameters (sealFieldOptions) : Required
The seal field parameters are required to create a new signature field or use an existing signature field.
Field Name (fieldName) : Required : Specifies the signature field's name. This must be a non-empty string. If signature field with this field name already exists, that field is used. else a signature field with this name will be created.
Visible (visible): Specifies whether the signature field should be visible or hidden. The default value of
true
creates a visible seal.Page Number (pageNumber) : Required : Specifies the page number to which the signature field should be attached. Page numbers are 1-based. It is only required if the signature field needs to be visible and, it does not exist in the pdf document. If this is provided along with the signature field then the page number should be same on which signature field is present in the document, else an error is thrown. This parameter will be ignored in case of invisible signature field.
Location (location) : Required : Specifies the coordinates of the seal appearance's bounding box in default PDF user space units. The location is only required if the signature field does not exist in the pdf document. If this is provided along with the existing signature field, then it is ignored. This parameter will also be ignored for invisible signature field.
- Left (left) : Required : The left x-coordinate
- Bottom (bottom) : Required : The bottom y-coordinate
- Right (right) : Required : The right x-coordinate
- Top (top) : Required : The top y-coordinate
To add the signature field explicitly, see how to place a signature field in a PDF.
Seal Appearance Parameters (sealAppearanceOptions)
Specifies seal field appearance parameters. These are an enumerated set of display items: NAME, DATE, DISTINGUISHED_NAME, LABELS and SEAL_IMAGE.
Display Options (displayOptions): Specifies the information to display in the seal. NAME and LABELS are the default values.
- NAME: Specifies that the certificate owner's name should be displayed.
- DATE: Specifies that the sealing date/time should be displayed. This value should not be mistaken for a signed timestamp from a timestamp authority.
- DISTINGUISHED_NAME: Specifies that the distinguished name information from the digital certificate should be displayed.
- LABELS: Specifies that text labels should be displayed.
- SEAL_IMAGE: Specifies the seal image should be displayed. If SEAL_IMAGE is given in appearance parameters and seal image is not passed in the request, the default Acrobat trefoil image is used.

Support of Trusted Timestamping and Document Level Permissions is only available through REST APIs and Java SDK. Other SDKs will support these features in future versions.
