D-Tools SI API Fields & Errors
D-Tools SI API field selection, and stable error codes — one request shape via MindCloud.
Once your first D-Tools SI request works, use this page to shape real production requests. MindCloud keeps the app-specific API details behind one REST format, so you can control arguments, pagination, filtering, fields, and errors without learning a separate convention for every provider. If you have not connected D-Tools SI yet, start with Connect to D-Tools SI.
Arguments
Arguments are the inputs an action needs. Put them in the JSON body under the arguments field. Each D-Tools SI action page documents its exact argument keys and types. It also shows which arguments are required. Keys are case-sensitive. Requests with missing or invalid required arguments fail.
Request format
Choose a D-Tools SI action and send a POST request to its Universal API run URL. Authenticate with your MindCloud API Key. Put the connection, arguments, and response controls in the JSON body.
| Piece | Where it goes |
|---|---|
arguments | An object in the JSON body. Put all action fields inside it. |
connectionId | An optional public connection id in the JSON body. The API selects the default or only valid connection when omitted. |
limit, offset, where, sort, fields | Response controls in the JSON body. |
Field selection
Use the fields body field to return only the response fields your code reads. Use dot notation for nested objects: fields=id,name,profile.email. Selection is applied to each row in data after the response is mapped, and id is kept whenever it exists so rows stay identifiable.
Responses and errors
Every D-Tools SI response is mapped into the same public envelope before it reaches your code: success, your rows in a data array (single-row actions return an array with one item), and optional meta. Failed requests return success: false with a stable code to branch on and a human-readable message:
{
"success": false,
"code": "CONNECTION_APP_MISMATCH",
"message": "Connection \"conn_123\" is not configured for this app."
}Check the HTTP status first: 401 or 403 for authentication and authorization, 400 for invalid request shape, and 5xx when MindCloud cannot complete the action upstream. Most failures come from a missing API Key, a missing or mismatched connection, or arguments that do not match the action page.
