Capsule CRM is a simple yet powerful CRM platform designed to help businesses…

Provider
capsule_crm
Category
Crm
Setup
One-click OAuth (we host the OAuth app)

Quick start

Call Capsule CRM from your generated app's worker code via the OverSkill composio client. The toolkit slug below maps to Capsule CRM's public Composio identifier — your app references it by name and OverSkill handles the OAuth round-trip.

// In your generated app's worker handler:
const composio = composioClient(env);

const result = await composio.execute(
  "CAPSULE_CRM_ACTION_NAME",
  { /* action parameters — see Actions section below */ }
);

return new Response(JSON.stringify(result), {
  headers: { "Content-Type": "application/json" }
});

Replace ACTION_NAME with one of the slugs listed in the Actions section below. The composio client handles auth + rate limits automatically — no API key is exposed to user code.

Setup

OverSkill hosts the OAuth application for Capsule CRM. End-users click Connect on the integration card in your app, complete the OAuth flow with Capsule CRM, and OverSkill stores the access token scoped to their account. No client_id / client_secret configuration needed on your side.

Supported auth schemes: OAUTH2, API_KEY.

Build with Capsule CRM

Open OverSkill, describe what you want to build, and reference Capsule CRM in your prompt — the AI will wire up the integration automatically.
