Sellsy (Client Credentials)

Sign up for a free Tenklo account (here) if you haven't already. Then navigate to Integrations -> Configure New Integration -> select Sellsy.

Go to Connections -> Add Test Connection -> Authorize, then enter your Sellsy Client Id and Secret shopper. Later, you'll let your users do the same directly from your app.

Let's make your first request to Sellsy (fetch a list of contacts). Replace the placeholders below with your Environment API key, integration ID, and connection ID:

curl -X GET "https://api.tenklo.dev/proxy/v2/contacts" \
  -H "Authorization: Bearer <NANGO-API-KEY>" \
  -H "Provider-Config-Key: <INTEGRATION-ID>" \
  -H "Connection-Id: <CONNECTION-ID>" \
  -H "Accept: application/json"

You can also fetch credentials dynamically via the Node SDK or API.
