Keep lead lists in Systeme.io updated without manual exports. The flow pulls every contact and tag, lets you filter by tag, and can add many contacts in one run. It helps marketers and small teams build segments and keep data clean.

Under the hood it uses HTTP requests to the Systeme.io API. Contacts, tags, and tagged contacts are fetched with safe pagination settings and a short wait between calls, so rate limits are not hit. Split nodes break the items into single records for easy processing. A final request adds new contacts when you load a list. You get reliable full data pulls and precise tag based lists that are ready for campaigns.

You need a Systeme.io API key and a header based credential in n8n. Set your tag IDs, test each fetch, then post a few sample contacts before running big batches. Expect hours of list work to drop to minutes, especially when migrating lists or building targeted segments on a schedule.

• Get all contacts from Systeme.io with limit and startingAfter pagination
• Fetch all tags and split them into single items for easy lookups
• Retrieve contacts that match one or more tag IDs using the tags query parameter
• Split Out nodes convert arrays into single records for downstream steps
• Built in request interval respects API rate limits during large pulls
• Bulk add contacts by posting records to the API in repeatable batches
• Single HTTP Header Auth credential reused across all HTTP Request nodes

• Reduce manual exports and imports from 2 hours to 10 minutes per week
• Streamline list building by 80 percent with tag based pulls
• Improve data completeness by 100 percent by paging until the last record
• Handle thousands of contacts without timeouts by spacing requests
• Connect one source of truth by pulling contacts and tags from the same API

1. Import the template into n8n: Create a new workflow in n8n > Click the three dots menu > Select 'Import from File' > Choose the downloaded JSON file.
2. You'll need accounts with Systeme.io. See the Tools Required section above for links to create accounts with these services.
3. In your Systeme.io account, create an API key in your settings. Keep it safe as you will paste it into n8n.
4. In n8n Cloud, open the Credentials section and create a new HTTP Header Auth credential for Systeme.io. If unsure, double click any HTTP Request node, choose Create new credential, and follow the on screen instructions.
5. Open the node named Systeme | Get all contacts and select your Systeme.io credential. Keep limit set to 100 so pagination works as designed.
6. Open Systeme | Get All tags, select the same credential, and execute the node. Note the tag IDs you need for your segments.
7. Open Systeme | Get contacts with tag and set the tags query parameter to one or more IDs, separated by commas. Run the node and review the Split Out3 output.
8. Open Systeme | Add contact. Map the body fields required by Systeme.io, such as email and name. Test with one sample record before sending larger batches.
9. If you see partial results or errors, increase the request interval to reduce API load and confirm the startingAfter pagination value is present.
10. Optional: add a Cron node to run daily or weekly. Connect it to the fetch nodes so lists refresh on a schedule.
