Ascertia’s SigningHub can be easily integrated into your core business applications using simple, industry-standard REST architectural style APIs. This ensures a seamless experience for your end users, using a range of integration options, to embed document preparation and signing within your own ecosystem.
Based on REST design while the payload is JSON making parsing quick and simple.
OAuth 2.0 to authorize client requests. All communication is secured using industry standard HTTPS (TLS 1.2).
API automates actions like create package, add documents, apply template, share, download, get status and much more!
Users interact with the document whilst SigningHub is embedded inside your web application. Users can view the document, fill-in any form fields and create their electronic or digital signature within your site. This creates a simple, efficient and trustworthy experience for the user.
Users interact with the SigningHub web interface to review and sign documents. The workflow is initiated by your business application and control returned once the user completes their respective actions. This is useful in situations where external users are required to sign documents, but do not have access to your internal business application.
Both tight and loose modes of integration can be used together within one document workflow, so internal users are interacting with SigningHub through their own web application interface, whilst external users interact directly with SigningHub.

All resources are located under the https://api.signinghub.com/ base URL. SigningHub authentication always uses the postfix “/authenticate”, whereas there are two versions of the API set. These are distinguished by using the postfix “/v2/” and “/v3” respectively. Version three of the API set requires SigningHub 7 or later. Ascertia recommends version 3 of the API set.

Check the API Reference and code as per the expected input and output.
The OAuth token has not expired. Note that the token expires after 24 hours.
Ensure that the client account which is used in the authentication call has rights assigned to the Integration area. Check via Enterprise Settings > Roles > Enterprise Settings.
If you have checked the above, and are still experiencing problems, then send an email to the support team with the following details:
Describe the integration requirements
Explain reproducible steps
If SigningHub is deployed on-premise, then provide:
System Platform details
SigningHub software version
Database version and patch level
Product log files
See the HTML form posting inside the tight integration. If you want to load SigningHub in your language then ensure you pass the correct language variable/information e.g. en-US, de-DE, etc. SigningHub supports 20+ languages.
No, SigningHub does not have a SDK. SigningHub supports a RESTful API interface that ensures no dependency upon development libraries. This makes the integration process lightweight and removes dependencies on local platform, language and device support. Look at the Getting Started section to learn more about integration options.
SigningHub uses REST architectural style APIs (interfaces explained in the Developer Manual), and hence you can use any language to integrate e.g. PHP, Node.js, Django, Java etc. We provide samples in C# so you can explore them along with the raw requests/responses to help you implement the APIs in your chosen respective language.
Simply change the base API URL to your own SigningHub instance whilst keeping the rest of the URL the same as documented, e.g. change SigningHub API to your own domain address so that your business application can authenticate to your own SigningHub after instance.
