Product: Adobe Sign
Area: Agreements
Scope: We have developed a web application (React as front-end and C# api as back end) and we would like to show the agreements related to each user logged into the application. The user is logged in the application trough Microsoft Outh2 authentication and Adobe Sign is synched with Entra ID.  we need to get token and agreements directly in the back end without any user interaction. We're trying to use the OAuth Server-to-Server. Is it the correct way?
Problem: Not authorized error

Hi, @marcobe4 

If a developer (you) wants to expose their customer’s Sign agreements within the developer application, the developer would need to:
1. Create an application / integration with Sign // https://opensource.adobe.com/acrobat-sign/developer_guide/index.html

2. “Certify” that application with Adobe (in order for the application to have permission to work with any customer Sign account) // https://www.adobe.com/go/esign-dev-cert

3. Then, the developer’s customer could: a/ authenticate into their Sign account (from within developer application), b/ developer application could then display customer’s agreements from customer’s Sign account
If developer needs assistance with this process, you can start with a Support Case, who can answer further questions // https://helpx.adobe.com/sign/admin/contact-support.html
