Put Pingdom TM (hidden) 2.1 API into 3.1 API


We (at OVH) are using the API 2.1 for TM:
- 2.1/
- 2.1/tms.summary.outage/${id}
- 2.1/tms.summary.performance/${id}

And we want to migrate our scripts to use the new 3.1 API (with API token auth), but I've some errors:
  "error": {
  "statuscode": 404,
  "statusdesc": "Not Found",
  "errormessage": "Please specify a valid API resource."

Your support told me that they are not available in API 3.1.

Is it possible to migrate it please?

Thank you
