Verdicts

Capsule CRM

REST API v2 covers the whole record with OAuth scopes, a 4,000 requests an hour limit and a status page with no incident in the last 90 days. There is no OpenAPI file, llms.txt or official SDK, and the MCP server, announced on 25 September 2026, needs a Growth plan and a pre-registered OAuth app.

Freshsales API

Contact upsert and bulk upsert of up to 100 records make creates safe to retry. No MCP server for Freshsales.

Before you call either

Capsule CRM

  1. Send Authorization: Bearer <token> to https://api.capsulecrm.com/api/v2. Projects use the old name in paths, /kases
  2. Follow the Link header for the next page. perPage goes up to 100 and the default is 50
  3. On 429, wait until the epoch time in X-RateLimit-Reset. The docs suggest one second between calls
  4. Ask for the read scope when the task only reads. A write with a read-only token answers 403 with insufficient_scope
  5. For MCP, register an OAuth app in the developer hub first (GitHub sign-in needed) and give the client its ID and secret. Personal API tokens are refused

Freshsales API

  1. Build the base URL from the bundle alias shown under the API key, https://<alias>.myfreshworks.com/crm/sales/api/
  2. Use /api/contacts/upsert rather than create, so a retry updates instead of duplicating
  3. Budget calls, since 1,000 an hour covers the whole account and 429s carry no Retry-After
  4. Add include=owner,sales_accounts to pull related records in one call
  5. Expect to see only what the key owner's role can see
