Passing `terms` replaces the whole list -- there is no incremental add/remove. If the dictionary is attached to any agent and the new `char_count` would push that agent over 10,000 combined characters, the request fails with `DICTIONARY_CHAR_LIMIT_EXCEEDED`. ## OpenAPI ````yaml /openapi.json patch /dictionaries/{id} openapi: 3.1.0 info: title: Vocobase Partner API version: '2.0' description: >- API for managing voice AI agents, documents, and calls on the Vocobase platform. servers: - url: https://api.vocobase.com/api/v2 description: Production security: - bearerAuth: [] tags: - name: Config description: >- Read and update partner configuration, webhook settings, and telephony credentials. - name: Agents description: Create, read, update, and delete voice AI agents. - name: Voices description: >- List voice tiers, available voices, and stream preview audio for agent configuration. - name: Documents description: Upload, manage, and delete knowledge base documents. - name: Agent Documents description: Link and unlink documents to agents for knowledge base integration. - name: Calls description: Initiate outbound calls and view call history. - name: Phone Numbers description: >- Import DIDs, assign agents for inbound routing, and re-sync carrier Application bindings. - name: Inbound Routing Policies description: >- Define pre-answer routing decisions for inbound calls before AI sessions are created. - name: Telephony Connections description: Create, list, rename, and disconnect named V2 telephony connections. - name: VoiceLink Management description: Manage VoiceLink reseller clients, DID mapping, and readiness sync. - name: Projects description: Organize agents into projects.
