Developer tools: API, webhooks, MCP
What Sayweek offers developers and automation: REST API, signed webhooks, Zapier, Make, Claude and ChatGPT (MCP) and an iCal link.
Updated:
Sayweek isn't only for the app: you can submit ideas from code, get notified about every event and let an AI assistant write drafts. Every write creates a draft that waits for your approval – nothing is published on its own.
What's available
- REST API – submit ideas, fetch posts and the week plan, create drafts with an API key. See API keys and scopes.
- Webhooks · n8n – signed JSON to your own URL on every event. See Webhooks.
- Zapier and Make – no-code automation with a ready-made Sayweek app. See Zapier and Make.
- Claude & ChatGPT (MCP) – plug Sayweek into your AI assistant. See Claude and ChatGPT.
- iCal / ICS – your post calendar as a subscription link. See iCal link.
Where to find them
- Open Settings → All integrations.
- Scroll to the Developer group, or type into Search integrations…, e.g.
api. - Click a card: its settings open in a side panel.

Role and plan
Only a workspace owner can create or revoke API keys, webhooks and iCal links. On the Solo plan the API and AI assistants can only read (plan, ideas, analytics); drafts and generation need Pro or higher – see the pricing page.
