Before You Start

The Offerslook API is designed for developers, engineers, or anyone else who’s comfortable creating custom-coded solutions or integrating with RESTful APIs.


There is one authentication methods for the API: HTTP Basic authentication. The easiest way to authenticate is using HTTP Basic authentication.

Network API Authentication: Enter network’s name as your username and supply your API Key as the password.

Affiliate API Authentication: Enter affiliate’s email as your username and supply your API Key as the password.


The API only supports JSON. So instead of XML, HTTP POST parameters, or other serialization formats, most POST and PATCH requests require a valid JSON object for the body.

HTTP Methods

The API supports 5 HTTP methods for interacting with resources:

  • GET

Make a GET request to retrieve data. GET requests will never cause an update or change to your data because they’re safe and idempotent.

  • POST

Use a POST request to create new resources. For example, make a POST request to a collection endpoint (like /lists) where the body of your request JSON is a new list.


Make a PATCH request to update a resource. With PATCH requests, you only need to provide the data you want to change.

  • PUT

Use a PUT request to create or update a resource. This is most useful for syncing subscriber data.


Make a DELETE request to remove a resource.


We give a valid, signed certificate for all API methods. If you’re manually coding submit URLs, change http to https in the URL, and make sure your connection library supports HTTPS.

Notice: Offerslook will support SSL within 1-2 month.


There are 4 main categories of parameters for each endpoint in the Offerslook API: path, query string, request body, and response body. The API Reference includes a list of all available parameters for each possible request, but these sections offer an overview of the 4 main categories and their subcategories.


We expose API errors in two ways: standard HTTP response codes and human-readable messages in JSON format. For example, the following code snippet shows an HTTP 405 error in the response headers:

And this snippet shows the human-readable error as a JSON object, we recommend reviewing the Application Error Codes for more context to help you troubleshoot.

For HTTP response codes, 4xx codes suggest a bad request. If you receive a 4xx response, we recommend reviewing the Http Status Codes for more context to help you troubleshoot.

Otherwise, you’re welcome to contact our support team[support@offerslook.com]. If you contact support, we recommend including the complete request you’re trying to make and the error code and response you’re receiving so they can help as quickly as possible.
