What the ClosingDealz API Is
An overview of the ClosingDealz API, what problems it solves, and how it enables programmatic lead ingestion and qualification inside your workspace.
Table of Contents
The ClosingDealz API is a programmatic entry point into the ClosingDealz platform that allows you to send leads directly into a workspace in real time, without relying on the user interface.
It is designed for teams and systems that need instant, reliable lead ingestion from external sources such as websites, backend services, internal tools, or custom integrations.
At its core, the API enables you to:
- Push leads into ClosingDealz as they are generated
- Preserve full lead structure, metadata, and contact information
- Ensure every lead is immediately available for qualification, routing, and follow-up
The API is workspace-scoped, meaning each request is automatically tied to a specific workspace through its API key. This guarantees strict data isolation and removes the need to manually manage workspace identifiers.
What the API Is Used For Today
The current version of the ClosingDealz API focuses on lead creation.
With a single endpoint, you can:
- Create company or contact leads
- Attach multiple contacts to a company
- Include communication details such as emails, phone numbers, socials, and addresses
- Apply labels and metadata at creation time
This makes the API ideal for:
- Custom lead capture flows
- Server-side form handling
- Integrations where speed matters more than UI interaction
What the API Is Not
The ClosingDealz API is not a replacement for the user interface.
It does not:
- Manage pipelines or deals
- Handle automation logic
- Replace qualification or sales workflows
- Expose full CRM functionality
Those capabilities live inside the platform itself.
The API’s role is to get high-quality leads into the system instantly, where ClosingDealz takes over.
As the platform evolves, the API will expand — but it will always prioritize speed, clarity, and correctness over surface area.
