Omitted fields keep their values. Disconnected connections cannot be updated. Requires a user-scoped API key, and `write:gl` for a general-ledger connection or `write:connections` for other connections. A general-ledger connection supports one legal entity. NetSuite rejects an ambiguous configuration with HTTP 409. Exchange, bank and card connections accept an optional `If-Match` with the `etag` of the connection. A changed connection returns HTTP 412. The check is not atomic with the provider call. General-ledger connections ignore `If-Match`. ## OpenAPI ````yaml openapi-public-preview.json PATCH /v1/connections/{connection_id} openapi: 3.1.0 info: title: Entendre API version: 1.0.0 description: Programmatic access to crypto-native accounting and treasury operations. servers: - url: https://api.entendre.finance description: Production API. security: - ApiKey: [] tags: - name: Organization description: Read your organization profile and find members for agent assignments. - name: Transactions description: Find transactions, inspect their details and create manual records. - name: Sources description: >- Manage wallets, exchange accounts, bank accounts and other transaction sources. - name: Assets description: Inspect asset acquisitions, remaining quantities and cost basis. - name: Journals description: >- Create and post journal entries, correct eligible entries and sync posted journals to a connected general ledger. - name: Documents description: >- Upload documents, check processing status and link supporting evidence to transactions. - name: Legal Entities description: Manage the legal entities used in your accounting records. - name: Ledger Accounts description: Manage your chart of accounts and find accounts for journal entries. - name: Tags description: Create and manage tags to classify your records. - name: Accruals description: >- Create and post accruals, inspect their status and reverse eligible entries. - name: Cash Application description: Match deposits to invoices and manage the resulting cash applications. - name: Classification description: >- Classify transactions in a batch, post eligible entries and inspect the results. - name: Revaluation description: Run asset revaluations for an accounting period and check their results. - name: Accounting Periods description: Check whether a period is ready to close, then close or reopen it. - name: Income Statement description: View revenue, expenses and net income for a reporting period. - name: Balance Sheet description: View assets, liabilities and equity as of a reporting date. - name: Trial Balance description: Review ledger account balances and debit and credit totals. - name: Closing Positions description: View asset positions at the end of a reporting period. - name: Treasury Balances description: Review treasury balances by asset and source. - name: Realized Gains & Losses description: Review realized gains and losses from asset dispositions. - name: Asset Tax Lots description: Inspect asset tax lots, remaining quantities and cost basis. - name: Schedule of Dispositions description: >- Review asset dispositions and their proceeds, cost basis and gains or losses. - name: Financial Insights description: Review financial insights for your selected reporting context. - name: Agents description: Create agents, schedule their work and inspect their runs. - name: Memory description: Read, search and maintain the memory files your agents use. - name: Connections description: Connect providers, manage authorization and disconnect. - name: GL Mapping description: >- Map ledger accounts and legal entities to your ERP.
