Rebilly REST API (2.1)

Download OpenAPI specification:Download


The Rebilly API is built on HTTP. Our API is RESTful. It has predictable resource URLs. It returns HTTP response codes to indicate errors. It also accepts and returns JSON in the HTTP body. You can use your favorite HTTP/REST library for your programming language to use Rebilly's API, or you can use one of our SDKs (currently available in PHP and Javascript).

We have other APIs that are also available. Every action from our app is supported by an API which is documented and available for use so that you may automate any workflows necessary. This document contains the most commonly integrated resources.


When you sign up for an account, you are given your first secret API key. You can generate additional API keys, and delete API keys (as you may need to rotate your keys in the future). You authenticate to the Rebilly API by providing your secret key in the request header.

Rebilly offers three forms of authentication: secret key, publishable key, JSON Web Tokens, and public signature key.

  • Secret API key: used for requests made from the server side. Never share these keys. Keep them guarded and secure.
  • Publishable API key: used for requests from the client side. For now can only be used to create a Payment Token and a File token.
  • JWT: short lifetime tokens that can be assigned a specific expiration time.

Never share your secret keys. Keep them guarded and secure.


You can create a JSON Web Token (JWT) via our JWT Session resource. Usage format: Bearer <JWT>

Security Scheme Type HTTP
HTTP Authorization Scheme bearer
Bearer format "JWT"


Only for the Tokens resource. You can create a Publishable API Key via our API Keys resource, by specifying the type as publishable.

Security Scheme Type API Key
Header parameter name: Authorization


When you sign up for an account, you are given your first secret API key. To do so please follow this link. Also you can generate additional API keys, and delete API keys (as you may need to rotate your keys in the future). All API keys can be restricted to a small set of permissions (restricted API keys).

Security Scheme Type API Key
Header parameter name: REB-APIKEY


Rebilly offers a Javascript SDK and a PHP SDK to help interact with the API. However, no SDK is required to use the API.

Rebilly also offers FramePay, a client-side iFrame-based solution to help create payment tokens while minimizing PCI DSS compliance burdens and maximizing the customizability. FramePay is interacting with the payment tokens creation operation.

Javascript SDK

The Javascript SDK is maintained within Github, and contains the installation and usage instructions.


For all PHP SDK examples provided in these docs you will need to configure the $client. You may do it like this:

$client = new Rebilly\Client([
    'apiKey' => 'YourApiKeyHere',
    'baseUrl' => '',

Using filter with Collections

Rebilly provides collections filtering. You can use ?filter param on collection to define which records should be shown in the response.

Here is filter format description:

  • Fields and values in filter are separated with :: ?filter=firstName:John.

  • Fields in filter are separated with ;: ?filter=firstName:John;lastName:Doe.

  • You can use multiple values using , as values separator: ?filter=firstName:John,Bob.

  • To negate the filter use !: ?filter=firstName:!John. Note that you can negate multiple values like this: ?filter=firstName:!John,Bob. This filter rule will exclude all Johns and Bobs from the response.

  • You can use range filters like this: ?filter=amount:1..10.

  • You can use gte (greater than or equals) filter like this: ?filter=amount:1.., or lte (less than or equals) than filter like this: ?filter=amount:..10.

  • You can create some predefined values lists and use them in filter: ?filter=firstName:@yourListName. You can also exclude list values: ?filter=firstName:!@yourListName

Expand to Include Embedded Objects

Rebilly provides the ability to pre-load additional objects with a request.

You can use ?expand param on most requests to expand and include embedded objects within the _embedded property of the response.

The _embedded property contains an array of objects keyed by the expand parameter value(s).

You may expand multiple objects by passing them as comma-separated to the expand value like so:


And in the response, you would see:

"_embedded": [
    "recentInvoice": {...},
    "customer": {...}

Expand may be utilitized not only on GET requests but also on PATCH, POST, PUT requests too.

Getting Started Guide

Rebilly's API has over 300 operations. That's more than you'll need to implement your use cases. If you have a use case you would like to implement, please consult us for feedback on the best API operations for the task.

Our getting started guide will demonstrate a basic order form use case. It will allow us to highlight core resources in Rebilly that will be helpful for many other use cases too.

Within 25 minutes, you'll have sent API requests (via our console) to create a subscription order.
