AttachInstances

POST

Add CVM instances to a scaling group.

Wire call

Converge Cloud is RPC over HTTP. There is one path — / — and the action travels in the X-TC-Action header. The /as/AttachInstances path used in the OpenAPI document is a documentation convenience so each action is addressable; it is not a route on the server.

curl

curl -sS https://as.api3.convergecloud.com/ \
  -H 'Authorization: TC3-HMAC-SHA256 Credential=<SecretId>/<YYYY-MM-DD>/as/tc3_request, SignedHeaders=content-type;host;x-tc-action, Signature=<sig>' \

Response

Fields are returned inside the Response envelope. Converge Cloud answers HTTP 200 for errors as well as successes, so read Response.Error rather than the status code — and test for the presence of that object, because Code is occasionally the empty string.

Field	Type	Description
ActivityId	string	Scaling activity ID
RequestId	string	The unique request ID, generated by the server, will be returned for every request (if the request fails to reach the server for other reasons, the request will not obtain a RequestId). RequestId is required for locating a problem.

Success

{
  "Response": {
    "ActivityId": …,
    "RequestId": "…"
  }
}

Error

{
  "Response": {
    "Error": { "Code": "…", "Message": "…" },
    "RequestId": "…"
  }
}
