Control the lifecycle
Set expiration, usage limits, or one-time behavior so links follow the actual lifetime of the resource.
SURLS / C# URL Shortener API
Automate secure link creation from APIs, services, background jobs, and business applications.
Link automation for .NET
Why this matters
Generate links from ASP.NET applications, background services, CRM workflows, document systems, and notification pipelines.
SURLS puts link creation, lifecycle, access control, domains, and delivery behavior behind one manageable endpoint.
Protect access
Use password or PIN protection and other available access rules when a destination should not be openly exposed.
Keep the URL stable
Manage the destination behind the public link so published URLs can continue working as your content changes.
Core capabilities
Built around the way this link is actually used.
Choose the controls that match the resource, recipient, and lifetime of the URL.
HttpClient integration
Designed as part of a managed link workflow so the public URL remains useful while its behavior stays configurable.
ASP.NET workflows
Designed as part of a managed link workflow so the public URL remains useful while its behavior stays configurable.
Background services

How it works
From destination to controlled link.
A simple workflow that scales from one manual link to application-generated infrastructure.
01
Choose a destinationStart with the URL, download endpoint, campaign destination, or application resource you want to expose.
02
Apply the policyConfigure the access and lifecycle rules that match the use case: protection, expiration, usage, or domain.
03
Publish the linkShare the resulting short URL anywhere a normal link can be used: browser, email, QR code, product UI, or API workflow.
04
Manage it laterReview activity and update the link without needing to replace every place where the public URL was published.

Frequently asked
Clear answers before you ship.
Can ASP.NET use the SURLS API?
Yes. ASP.NET and other .NET applications can call the HTTP API with HttpClient or another supported HTTP client.
Can I combine multiple controls?
Yes. SURLS is designed so lifecycle and access controls can be combined where the workflow requires more than one condition.
Can I use this from an application?
Yes. SURLS provides API-oriented link infrastructure so applications can create and manage links programmatically.
Can I use my own domain?
Custom-domain support lets you connect a domain, verify DNS, and create links using that domain.
