Introduction

Duda's Partner API is organized around REST. Our API has predictable resource-oriented URLs, accepts JSON request bodies, returns JSON-encoded responses, and uses standard HTTP response codes, authentication, and verbs.

The Partner API is designed to be a Management API, which means you can integrate Duda's white-labeled resources (sites, accounts, etc.) into your own workflows and/or services.

Duda's primary path for all production API endpoints is: https://api.duda.co/api

📘

To access the Duda API, you need to request access through your websites dashboard or submit a request to our support team.

Authentication & Security

Duda's APIs use basic HTTP authentication to authenticate requests and allow access to resources.

As part of getting access to the API, you will get a user name and password specific to your account. The user and password need to be joined with a colon and base64 encoded before passing it into the Authorization header. An example cURL request:

curl -H 'Authorization: Basic <base64-token>' 'https://api.duda.co/api'

Duda's APIs are only available over HTTPS to ensure that data is securely transmitted over the internet. In addition, Duda only accepts connections using TLS v1.2 and higher.

Rate Limits

Duda's servers enforce rate limits to maintain a level of performance and stability for all Duda customers. We have both global and endpoint-specific rate limits.

For all API endpoints, there is a hard limit of 10 API calls per second. If you are running any batch process against the API, Duda recommends limiting your requests to one every 125ms (8 a second) to prevent hitting the rate limit.

The following endpoints have their own specific limits:

• Publish Site and Unpublish Site: 20 calls per minute
• Create Site: 60 calls per minute
• Create Account: 60 calls per minute
• Refresh Collection Data by External ID: 1 call every 15 minutes
• Get Contact Form Submissions: 800 calls per minute
• Analytics: 60 calls per minute
• Form Submissions: 300 calls per minute
• Batch Membership Invitations : 10 calls per minute

Duda will respond with a 429 Too Many Requests status code if you hit the rate limit.

Errors

When Duda detects an error in your request, we will respond with a 400 (Bad Request) HTTP response and return a JSON error object:

{
  "error_code": "ResourceNotExist",
  "message": "Site with alias 'badName' doesn't exist"
}

Good-to-Know

Dates

There are some Duda APIs that return date-time values. Duda formats these in the standard universal full date-time pattern in the UTC timezone. The format is: yyyy-mm-ddThh:mm:ss. So for example: 2016-11-15T22:55:53 would be November 15th, 2016 at 10:55:53 PM UTC.

When sending dates to Duda, you can use the full universal format above, or just the YYYY-MM-DD format. If you omit the time, Duda will default that time to the beginning of the day.

Languages

There are some parts of the API where Duda returns real-world content to display to users. As part of this, we are able to deliver localized content. Below you will see a full list of languages that the Duda platform (UI) is localized for along with their corresponding language codes.

Python Requests

All endpoints require a user-agent header to be present. Some tools like cURL will add the user agent automatically. The same holds true for helper libraries such as node-fetch. The cURL, Ruby, Node and JavaScript code examples included for each endpoint all handle the user-agent header for you. If you are using Python, your header should include an explicit user-agent in your request.
