Create conversation

Initiate a new direct message conversation with a specified user. If a conversation already exists with the recipient, the message is added to the existing thread. **Currently supported platforms:** Twitter/X only. Other platforms will return `PLATFORM_NOT_SUPPORTED`. **DM eligibility:** Before sending, the endpoint checks if the recipient accepts DMs from your account (via the `receives_your_dm` field). If not, a 422 error with code `DM_NOT_ALLOWED` is returned. You can skip this check with `skipDmCheck: true` if you have already verified eligibility. **X API tier requirement:** DM write endpoints require X API Pro tier ($5,000/month) or Enterprise access. This applies to BYOK (Bring Your Own Key) users who provide their own X API credentials. **Rate limits:** 200 requests per 15 minutes, 1,000 per 24 hours per user, 15,000 per 24 hours per app (shared across all DM endpoints).
