Support Cases Over the API, MCP and the CLI

List, read, open, reply on and close your support cases with BankSync from a script, an AI agent or an automation, always as a person and never with more reach than they have in the app.

On this page

Your conversations with BankSync support are not only on the app's Support page. An API key, an MCP client (Claude, Cursor, the copilot), the CLI and an automation can list them, read them, open a new one, reply, and close one you raised.

Who the call is for#

Every support call is made as a person, and BankSync support sees exactly what that person would see in the app:

  • A key or an OAuth app acts as the user it belongs to, in the key's workspace.
  • An MCP client acts as the member who connected it.
  • An automation acts as the member who approved its grant, and anything it writes is marked as sent by the automation on their behalf.

So a key never sees a case its user could not see, can only close a case its user raised, and is held to the same limit on open cases (ten).

What you need#

  • A key with support:read to list and read, and support:write to open, reply and close.
  • Support is on in every workspace; there is nothing to enable.

Over the API#

WhatRequest
List your casesGET /v1/support/cases
Read oneGET /v1/support/cases/{caseId}
Open a casePOST /v1/support/cases
Reply on a casePOST /v1/support/cases/{caseId}/messages
Close a casePOST /v1/support/cases/{caseId}/close
Shell
curl -X POST https://api.banksync.io/v1/support/cases \  -H "Authorization: Bearer $BANKSYNC_API_KEY" \  -H "Content-Type: application/json" \  -d '{"subject":"Sync stalled","message":"Nothing has synced since Monday.","idempotencyKey":"sync-stalled-2026-09-29"}'

Send the same idempotencyKey when you retry an open or a reply, and nothing is opened or posted twice. A reply reaches BankSync support straight away and cannot be taken back.

From the CLI#

Shell
banksync support listbanksync support get case_123banksync support open --subject "Sync stalled" --message "Nothing has synced since Monday."banksync support reply case_123 --message "Here is the log you asked for."banksync support close case_123

Over MCP#

The tools are list_support_cases, get_support_case, create_support_case, reply_to_support_case and close_support_case. A case's words come from people: an agent treats them as data, never as instructions.

In an automation#

The same five operations are steps under Support, and the support triggers (a case opened, support replied, a case closed) start an automation. An automation's replies count against a limit of 20 a day for the whole workspace.

When it says no#

AnswerWhat it means
403closing a case someone else raised, or a key missing its scope
404a case you cannot see answers the same as one that does not exist
409the case is already closed, or closed too long ago to reply on
429 TOO_MANY_OPEN_CASESyou already have ten open cases: reply on one of those
503 SUPPORT_UNAVAILABLEsupport could not be reached just now: retry shortly

Reopening a case, rating one, following a colleague's case and adding attachments are done in the app.
