Getting started with the API



The ActiveCampaign API is used to enable integrations between your ActiveCampaign account and 3rd party services or a custom interface you created.

What is an API?

API is short for Application Programming Interface and it allows for one application to talk to another. We recommend using the ActiveCampaign API for any functionality needed outside of the main user interface, such as enabling an integration.

How to obtain your ActiveCampaign API URL and Key

In order to enable an integration between your ActiveCampaign account and a 3rd party application, you will need to first obtain your API URL and Key. The API URL and Key can be thought of as your username and password to your ActiveCampaign account. When you give this information to a 3rd party application, they will be able to access your account to sync information or perform other tasks.

  Each user in your ActiveCampaign account has their own API URL and Key.

If integrations are set up with a user’s API credentials, deleting the user will cause integrations to break. You must update affected integrations with another user's API credentials since there is no account default API.

To obtain your ActiveCampaign API URL and Key, follow these steps:

  1. Click "Settings" (gear icon) on the left menu. 
  2. The Account Settings menu will appear. Click the "Developer" option
  3. Copy your API URL and Key and paste it into your 3rd party application.

How to reset your API information

In the event that your API information has been compromised, you can reset your key.

To reset your API information:

  1. Navigate to the Developer Settings page.
  2. Click the "Reset API Key" button.
  3. A confirmation window will appear. Click "Reset API Key" to confirm the change.

Note that you will need to update all 3rd party applications with your new API information.

API for Developers

With the ActiveCampaign API, you can sync contact information, view contact information, add contacts to automations, create and send campaigns, and much much more. Our API is structured around REST, HTTP, and JSON and requires basic authentication (actual user account within the software or a valid API URL and Key).

Access the ActiveCampaign Developer portal.

In order to work with our API, you’ll need the following:

  • Valid ActiveCampaign account (a trial version will also work)
  • Experience with creating custom-coded solutions and/or integration with REST APIs
  • Ability to submit HTTP requests from your server

We provide a list of available API methods along with detailed descriptions of each parameter, as well as examples in actual code. Our community forum is a great resource as you're learning how the API works. There, you can interact with other developers and ask questions about the API. In addition, we have certified consultants that can assist you with your API needs.

Troubleshooting the API for Developers

If you are receiving script errors, missing data, or anything prohibiting you from fully using the API, please contact our Customer Experience Team and provide the following information:

  • Full API request URL (including all parameters)
  • If it's a POST request, your POST data
  • The expected response/action
  • The actual response received from the server, and action performed (if any)

Please note that while we'll do our best to help you troubleshoot your API issues, this can provide certain challenges. This is because it's not possible for us to see what is happening with your application, script, or environment. 

If you have a more general question (such as how a specific API method works or why a specific API is not returning data), we recommend posting the issue in our user forum where it is documented publicly so other user can help, share their own experiences, and help future users learn from past experiences.

If you need assistance with configuring something using the API, we recommend working with one of our certified consultants or posting in our community forum.
