Bearer token auth

Create API keys per workspace with read or write scope. Keys are stored hashed.

HMAC-signed webhooks

Receive events on tasks, projects and comments – with HMAC-SHA256 signature for verification.

No-code integrations

Works directly with Zapier, Make.com, n8n and Workato.

Quickstart

Create an API key in the workspace settings, then:

# List all projects
curl -H "Authorization: Bearer flnk_..." \
  https://app.flenio.ch/api/v1/projects

# Create a task
curl -X POST -H "Authorization: Bearer flnk_..." \
  -H "Content-Type: application/json" \
  -d '{"project_id":"...","title":"New task","priority":"high"}' \
  https://app.flenio.ch/api/v1/tasks

# Mark task as done
curl -X PATCH -H "Authorization: Bearer flnk_..." \
  -H "Content-Type: application/json" \
  -d '{"status":"done"}' \
  https://app.flenio.ch/api/v1/tasks/{id}
