GoHighLevel Documents & Contracts Public API Guide

If you use tools like ClickUp alongside GoHighLevel, you can streamline document workflows by connecting systems through the Documents & Contracts public APIs. This guide shows you how to work with the document management endpoints so you can upload, list, and automate documents from your own integrations.

The information below is based on the official GoHighLevel Documents & Contracts API reference and is organized as a practical how-to article for implementers and agency teams.

What the GoHighLevel Documents API Does

The Documents & Contracts public APIs in GoHighLevel allow you to manage documents programmatically instead of only through the web interface. You can use these endpoints to:

  • Upload new documents and contracts to a sub-account
  • Retrieve a list of existing documents
  • Access details about a specific document
  • Support automations that depend on document records

All of this is done over HTTPS using standard REST-style endpoints and JSON payloads. Understanding how these endpoints work lets you build custom automation and integrations that extend GoHighLevel across your tech stack.

Before You Start with GoHighLevel APIs

To use the Documents & Contracts API, you need a few prerequisites in place:

  • An active GoHighLevel account
  • Access to a sub-account where you will manage documents
  • API credentials (usually an API key) with permission to work with documents
  • Basic familiarity with making HTTP requests (GET, POST, etc.)

If you are setting this up for a client agency, confirm that the correct sub-account is selected and that the API key is scoped appropriately for documents and contracts.

How Authentication Works in GoHighLevel

All GoHighLevel Documents & Contracts API requests must be authenticated. Typically, authentication is handled via an API key sent in the request header. The exact header name and format are defined in the official API documentation, but the general pattern is:

  • Include your API key in the request headers
  • Send requests over HTTPS only
  • Use keys that are associated with the correct sub-account

Never expose your API key publicly. Store it securely in environment variables or a secrets manager in your application.

Core GoHighLevel Documents Endpoints

The Documents & Contracts public APIs expose several key endpoints. While the specific URL paths are defined in the official reference, the key operations follow standard REST naming:

  • List documents – Fetch all documents for a sub-account
  • Upload document – Create or upload a new document
  • Get document by ID – Retrieve details for a single document

Each endpoint will specify:

  • HTTP method (GET, POST, etc.)
  • Required headers, including authentication
  • Request body fields (for POST and PUT)
  • Response schema and error codes

You can find exact endpoint paths, parameters, and example payloads in the official reference at GoHighLevel Documents & Contracts Public APIs.

Step-by-Step: Listing Documents in GoHighLevel

The most common starting point is listing documents for a sub-account. This gives you an overview of existing records that you can then filter or process in your application.

1. Prepare your GoHighLevel API request

To list documents, use the corresponding GET endpoint from the public API reference. In your HTTP client or integration tool:

  1. Set the request method to GET.
  2. Use the documents listing endpoint URL from the GoHighLevel reference.
  3. Add your authentication header with a valid API key.
  4. Include any optional query parameters documented in the API (such as pagination or filters, if supported).

2. Send the request and review the response

When you send the request, the GoHighLevel API will return a JSON response that typically includes:

  • A collection (array) of document objects
  • Fields such as document ID, name, status, and timestamps
  • Pagination information if there are multiple pages of results

Use the IDs returned here to work with individual documents or to drive automations in your CRM, pipelines, or external tools.

Step-by-Step: Uploading a Document to GoHighLevel

Uploading a document or contract via API is essential when you want to automate document generation or sync files from another platform into GoHighLevel.

1. Gather required document data

Before you call the upload endpoint, make sure you have:

  • The file content or a method to send it (for example, multipart/form-data or base64, depending on the endpoint specification)
  • Metadata required by the GoHighLevel API, such as document name or type
  • The correct sub-account context for where the document should live

2. Build the upload request

Follow the official endpoint format for uploading a document:

  1. Set the method to POST.
  2. Use the Documents & Contracts upload endpoint URL from the API reference.
  3. Include authentication headers for GoHighLevel.
  4. Attach the document file and any required metadata in the request body, using the content type specified in the documentation.

3. Validate the API response

On a successful upload, the GoHighLevel API returns details about the new document, such as:

  • Document ID
  • Document name
  • Status or processing state
  • Timestamps for creation

Store the returned document ID on your side so you can reference the file in later automations, such as sending contracts for signing or linking documents to contacts.

How to Retrieve a Single Document in GoHighLevel

Once you know a document ID, you can fetch details about that specific record.

Using the document-by-ID endpoint

  1. Set the HTTP method to GET.
  2. Use the document details endpoint and substitute the document ID in the URL path, as described in the API reference.
  3. Include the required GoHighLevel authentication header.
  4. Send the request and read the JSON response for document details.

This is especially useful in workflows where you need to check the status of a document or display document data in another system.

Best Practices for GoHighLevel API Integrations

When using the Documents & Contracts public APIs in GoHighLevel, follow these practices for reliability and security:

  • Secure API keys – Keep keys in environment variables or a vault and rotate them periodically.
  • Handle rate limits – If the API enforces rate limits, add retry logic with backoff.
  • Log requests and responses – Capture request IDs and error messages for debugging.
  • Validate inputs – Check file sizes, types, and required fields before sending data to the API.
  • Use test environments – When available, test against a staging or sandbox environment before production.
