Freemius API (1.0)

Welcome to the Freemius API Documentation!

You can use our API to access Freemius API endpoints, which can get information on various aspects of Freemius.

  • Manage products.
  • Manage license verifications.
  • Create custom integration with your SaaS.

If you're using Freemius for a WordPress product, please check out our official SDK.

Bearer Token Auth

Freemius API supports Bearer Token authentication for product-specific operations.

To retrieve your API token:

  1. Go to the Freemius Developer Dashboard.
  2. Open the Settings page of the relevant product.
  3. Click on the API Token tab.
  4. Copy the API Bearer Authorization Token from the UI.

Use this token by including it in the Authorization header of your API requests:

Authorization: Bearer {api_token}

Bearer tokens are scoped to a specific product. This means they can only be used with endpoints under the /products/{product_id}/ namespace. For example:

GET /products/12345/users.json
Authorization Bearer {api_token}

Requests to endpoints outside the product scope will result in an authorization error.

Other Scopes and Authentication

The Freemius API is organized around different scopes, based on the top-level entity of the operation:

For example, let's say you want to list all payments of a product. This operation can be done in several scopes:

  • Product Scope: /products/{product_id}/payments.json.
  • Developer Scope: /developers/{developer_id}/products/{product_id}/payments.json.

On the other hand, if a user would want to list their payment, then endpoint will be scoped to the user:

  • User Scope: /users/{user_id}/payments.json.

Some operations can be done from a particular scope only. For example only a developer can update a plan of a product or create a new plan. So the following operations will work:

  • Update Plan: POST /developers/{developer_id}/products/{product_id}/plans/{plan_id}.json
  • Create Plan: POST /developers/{developer_id}/products/{product_id}/plans.json

If you try to perform the same operation on a product scope, it will return an error. The scopes provides a way to control access and permissions for different entities in the Freemius ecosystem.

Currently, Bearer Token authentication is supported for product scope only. If you need access to endpoints in others scopes, use the secret-key based authentication with the following SDKs:

For most use cases, managing your products, licenses, and customers through the Developer Dashboard or Customer Portal provides all the necessary capabilities.
