Each user in your ActiveCampaign account has their own unique API key. If a user is deleted, integrations using their API credentials will break.

​
Locating Your API URL

Your API URL is unique to your ActiveCampaign account and includes your data center region.

1

Access Developer Settings

Sign in to your ActiveCampaign account, click the Settings gear icon (⚙) in the top-right corner of the header, then select Developer from the Settings menu on the left.

2

Copy Your API URL

In the API Access section, find the URL field displaying your unique URL and copy the entire URL.

  • Format: https://{account-name}.api-{region}.com
  • Example US: https://acmecompany.api-us1.com
  • Example EU: https://acmecompany.api-eu1.com
  • Note: Copy the full URL including https:// but without any trailing path

​
Locating Your API Key

Each ActiveCampaign user has a unique API key for authenticating API requests.

1

Find and copy your API key

In Settings > Developer, find the Key field below the URL in the API Access section. Copy the full value and store it securely for use later.

  • Note: Never share your API key publicly or commit it to version control.
  • If compromised, click Reset API Key to regenerate it — this will break any existing integrations using the old key.
