Platform-Specific Settings
Use platform_overrides to customize content for Threads:
{
"content": "Default content for all platforms",
"platform_overrides": {

}
}
}Rate Limits
Threads enforces its own rate limits. RelayAPI automatically queues and retries posts when platform rate limits are reached. See Rate Limits for details.
