Dated API versions, a year's support and 6 months' deprecation notice with Deprecation and Sunset headers. MCP server in open beta since 1 July 2026.

Before you call either

Microsoft Dynamics 365 Sales

  1. Send OData-MaxVersion: 4.0, OData-Version: 4.0 and Accept: application/json, and name columns with $select on every read
  2. Page with Prefer: odata.maxpagesize (up to 5,000) and follow @odata.nextLink. $skip is not supported
  3. On 429, wait the seconds in Retry-After. The x-ms-ratelimit-* headers are for debugging, not pacing
  4. Use PATCH on an alternate key to upsert, and add If-Match: * when an update must not create a record
  5. For MCP, call describe for logical table and column names before read_query. Update any allow list that still names describe_table, list_tables or fetch

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
