Setting up Loops
From the connector definition itself: where to find the credentials, what they need to be allowed to do, and which API this adapter talks to.
This connector uses the Loops v1 REST API (https://loops.so/docs/api-reference).
Setup:
- Sign in to https://app.loops.so → Settings → API → Create API key.
- Pick the scope: Public API (recommended for most use) or higher.
- Copy the key (prefixed). Set
LOOPS_API_KEY.
Authentication: Authorization: Bearer ${LOOPS_API_KEY}.
Mental model: Loops is event-driven. You send events (like 'user.signed_up', 'subscription.upgraded'), and those events trigger loops (the email automations you build in the UI). For transactional sends (password reset, magic link), use loops_send_transactional_email with a pre-built transactional template ID.
Contacts: identified by email (primary key). Use userGroup to bucket contacts (free / pro / churned). Custom properties via the properties object.
Transactional templates: built in the Loops UI under Transactional. Each has a transactionalId (visible after publishing). Variables in the template ({{firstName}}) are filled from the dataVariables map on send.
Idempotency: events can include an eventName + idempotencyKey — duplicate calls with the same idempotency key within 24h are deduped.
Rate limits: 10 req/sec per API key for sends, higher for reads. On 429, back off.
Out of scope here: campaign management (Loops campaigns are visual UI-only), audience filters, attribution reports.
