Connect n8n to GuardenerAI with the API.

Step by step

1. Save the key as a credential

   In an HTTP Request node set Authentication to Generic Credential Type, then Header Auth. Create the credential with Name X-Api-Key and your key as the Value. Every GuardenerAI request in the workflow can reuse it.

2. Start the workflow

   Use the trigger for the app where your leads arrive, or a Webhook node if another system can post to n8n.

3. Look the person up by email

   Add an HTTP Request node, method GET, with the Header Auth credential. Lower-case the email in the expression, because the match is case-sensitive.

   Copy

   https://YOUR-ORG.guardenerai.com/api/leads?filter=email:equals:{{ $json.email.toLowerCase() }}

4. Branch with If

   Add an If node that checks whether totalElements equals 0. The true branch is a new lead. The false branch is a lead you already have, and content[0].id is its id.

5. Create or update

   On the true branch add an HTTP Request node, method POST, to /api/leads, with Send Body on and JSON as the body. firstName, lastName and email are required. On the false branch send a PUT to /api/leads/{id} with every field you want to keep, because a PUT replaces the whole record. Then publish the workflow.

   Copy

   {
     "firstName": "{{ $('Webhook').item.json.first_name }}",
     "lastName": "{{ $('Webhook').item.json.last_name }}",
     "email": "{{ $('Webhook').item.json.email.toLowerCase() }}",
     "message": "{{ $('Webhook').item.json.message }}",
     "sourceMedium": "n8n",
     "sourceCampaign": "contact form"
   }
