Salesflare

The REST API has a public Swagger 2.0 file covering 71 operations, with typed filters on every list call and a 30-day trial that needs no card. No rate limit numbers, API changelog, SDK or audit log were found in the reviewed documentation, and API keys carry no documented scopes.

Before you call either

folk API + MCP

  1. Send X-API-Version: 2025-06-09 on every REST call
  2. Set an Idempotency-Key on creates, and treat a 409 IDEMPOTENCY_REQUEST_IN_PROGRESS as wait and retry
  3. On a 429, wait until details.retryAfter, and remember all your keys share one 600-a-minute budget
  4. Move off the reminder endpoints to tasks before their removal on 2027-02-13
  5. Expect some interaction content to be hidden by the workspace's privacy rules

Salesflare

  1. Send Authorization: Bearer <API key> to https://api.salesflare.com. A person creates the key in Settings, API keys
  2. Set limit on every list call. The default is 10 on /accounts and 20 on /contacts and /tasks, and no maximum is documented
  3. Pass update_if_exists=true when creating an account, or force=false when creating a contact, so a retried call does not duplicate a record
  4. Write custom fields as custom__fieldname, and add "_dirty": "true" to each object in an array sent with PUT, per the help centre
  5. Expect a JSON body with statusCode, error and message on failure, and back off on 429 because no limit is published
