/help I want to use the APi reference. However, I get a 400 error when I try to create one for ElevenLabs. How do I create an API request using the following code? I need step-by-step instructions. POST https://api.vapi.ai/provider/11labs/pronunciation-dictionary Content-Type: application/json Authorization: Bearer YOUR_API_KEY { "name": "Custom FICA Pronunciation", "rules": [ { "stringToReplace": "FICA", "type": "phoneme", "phoneme": "/ˈfaɪkə/", "alphabet": "ipa", "caseSensitive": true } ] }

Hi SKoess, Follow these steps to create the pronunciation dictionary via the API and troubleshoot the 400: 1. Prepare your API key - Get your Vapi API key from Dashboard (Dashboard → API Keys). - Use it exactly as: Authorization: Bearer YOUR_API_KEY 2. Validate request JSON - Use this minimal valid body (remove extra fields if 400 persists): { "name": "Custom FICA Pronunciation", "rules": \[ { "stringToReplace": "FICA", "type": "phoneme", "phoneme": "/ˈfaɪkə/", "alphabet": "ipa" } \] } - Note: the docs example does not require "caseSensitive". If you need case-sensitive rules, add it but try without first. 3. CURL example (replace YOUR_API_KEY): curl -X POST "https://api.vapi.ai/provider/11labs/pronunciation-dictionary" -H "Authorization: Bearer YOUR_API_KEY" -H "Content-Type: application/json" -d '{ "name":"Custom FICA Pronunciation", "rules":\[{"stringToReplace":"FICA","type":"phoneme","phoneme":"/ˈfaɪkə/","alphabet":"ipa"}\] }' 4. Common causes of 400 and quick fixes - Malformed JSON: run through a JSON linter or use the single-line curl payload above. - Missing or wrong Authorization header: ensure no trailing spaces, “Bearer ” prefix, and correct key. - Invalid field names/values: ensure "type" is "phoneme", "alphabet" is "ipa" (lowercase). - If using BYOK ElevenLabs flow: 400 can occur if ElevenLabs phoneme rules aren’t allowed for your model — phoneme rules require an ElevenLabs-compatible model when used in TTS (but dictionary creation should still succeed). 5. If you get a 400 response, capture and share: - Full HTTP response body (error message) - The exact curl/HTTP client command you used - Whether you're using Vapi's ElevenLabs integration or your own ElevenLabs API key (BYOK) Reference: Pronunciation dictionaries docs: https://docs.vapi.ai/assistants/pronunciation-dictionaries

Here is the error code: "message": "Unsupported data type. Either file or rules must be provided.", "error": "Bad Request", "statusCode": 400 } Also, please note that I am using the Vapi API reference. https://cdn.discordapp.com/attachments/1453080975318843436/1455568135972458655/Screenshot_2025-12-30_at_8.27.37_a.m..png?ex=695532f6&is=6953e176&hm=aede6818d37cd5142d7bdc862a2f50e84037ea2db7bba6643efc33ac5215e440&
