Prerequisites
Before creating an ActiveCampaign credential in Nexla, you need to obtain your API URL and API key from your ActiveCampaign account. These credentials authenticate Nexla with the ActiveCampaign API and should be kept secure.
-
Sign in to your ActiveCampaign account.
-
Navigate to My Settings by clicking your account icon in the upper right corner and selecting Settings from the dropdown menu.
-
Click on the Developer tab to access the developer settings page.
-
On the Developer page, locate the API Access section. This section displays your API credentials.
-
Copy your API URL. This is a unique URL specific to your ActiveCampaign account that serves as the base URL for all API requests. The API URL typically follows the format
https://[your-account].api-us1.comor similar, depending on your account's data center. -
Copy your API Key. This key authenticates API requests and provides access to your ActiveCampaign account data. The API key is a long alphanumeric string.
Your API URL and API Key are unique to your ActiveCampaign account and should be kept secure. Do not share these credentials publicly or commit them to version control systems. If you suspect your API key has been compromised, regenerate it immediately in your ActiveCampaign account settings.
For additional information about ActiveCampaign API authentication and credential management, see the ActiveCampaign API documentation.
Authenticate
Credentials required
| Field | Required | Secret | Description |
|---|---|---|---|
| API URL | Yes | No | Your API URL can be found in your account on the My Settings page under the "Developer" tab. |

Create a credential in Nexla
- After selecting the data source/destination type, click the Add Credential tile to open the Add New Credential overlay.
New Credential Overlay – ActiveCampaign

-
Enter a name for the credential in the Credential Name field and a short, meaningful description in the Credential Description field.
-
Enter your ActiveCampaign API URL in the API URL field. This should be the complete base URL for your ActiveCampaign account's API, typically in the format
https://[your-account].api-us1.comor similar. You can find this URL in your ActiveCampaign account under My Settings → Developer → API Access. -
Enter your ActiveCampaign API key in the API Key field. This key authenticates Nexla with the ActiveCampaign API and should match the API key obtained from your ActiveCampaign account settings. The API key is sent in the
Api-Tokenheader for all API requests.The API key provides full access to your ActiveCampaign account data through the API. Keep your API key secure and do not share it publicly or commit it to version control systems. ActiveCampaign uses the API key in the
Api-Tokenheader for authentication, which allows Nexla to make authenticated requests to your account. -
Click the Save button at the bottom of the overlay. The newly added credential will now appear in a tile on the Authenticate screen during data source/destination creation.
Use as a data source
To create a new data flow, navigate to the Integrate section, and click the New Data Flow button. Select the ActiveCampaign connector tile, then select the credential that will be used to connect to the ActiveCampaign instance, and click Next; or, create a new ActiveCampaign credential for use in this flow.
Endpoint templates
Nexla provides pre-built templates that can be used to rapidly configure data sources to ingest data from common ActiveCampaign endpoints. Select the endpoint from which this source will fetch data from the Endpoint pulldown menu. Available endpoint templates are listed in the expandable boxes below.
Once the selected endpoint template has been configured, click the Test button to the right of the endpoint selection menu to retrieve a sample of the data that will be fetched. Sample data will be displayed in the Endpoint Test Result panel on the right, allowing you to verify that the source is configured correctly before saving.
Manual configuration
ActiveCampaign data sources can also be manually configured to ingest data from any valid ActiveCampaign API endpoint, including endpoints not covered by the pre-built templates, chained API calls, or custom request parameters. Select the Advanced tab at the top of the configuration screen, and follow the instructions in Connect to Any API to configure the API method, endpoint URL, date/time and lookup macros, path to data, metadata, and request headers.
ActiveCampaign API endpoints follow the pattern {API_URL}/api/3/{resource_type}, where {API_URL} is your account-specific API URL and {resource_type} is the type of resource you want to access. For a complete list of available ActiveCampaign API endpoints, see the ActiveCampaign API documentation.
Once all of the relevant settings have been configured, click the Create button in the upper right corner of the screen to save and create the new ActiveCampaign data source. Nexla will now begin ingesting data from the configured endpoint and will organize any data that it finds into one or more Nexsets.
Use as a destination
Click the + icon on the Nexset that will be sent to the ActiveCampaign destination, and select the Send to Destination option from the menu. Select the ActiveCampaign connector from the list of available destination connectors, then select the credential that will be used to connect to the ActiveCampaign organization, and click Next; or, create a new ActiveCampaign credential for use in this flow.
Endpoint templates
Nexla provides pre-built templates that can be used to rapidly configure destinations to send data to common ActiveCampaign endpoints. Select the endpoint to which data will be sent from the Endpoint pulldown menu. Then, click on the template in the list below to expand it, and follow the instructions to configure additional endpoint settings.
Manual configuration
ActiveCampaign destinations can also be manually configured to send data to any valid ActiveCampaign API endpoint. Select the Advanced tab at the top of the configuration screen, and follow the instructions in Connect to Any API to configure the API method, data format, endpoint URL, request headers, attribute exclusions, record batching, and response webhooks.
ActiveCampaign API endpoints typically expect JSON format for request bodies. Endpoints follow the pattern {API_URL}/api/3/{resource_type} for create operations and {API_URL}/api/3/{resource_type}/{resource_id} for update operations, where {API_URL} is your account-specific API URL. For update/upsert operations, include the ID of the object to be updated at the end of the URL.
Save & activate
Once all endpoint settings have been configured, click the Done button in the upper right corner of the screen to save and create the destination. To send the data to the configured ActiveCampaign endpoint, open the destination resource menu, and select Activate.
The Nexset data will not be sent to the ActiveCampaign endpoint until the destination is activated. Destinations can be activated immediately or at a later time, providing full control over data movement.
