FAQ
Where do I connect an integration?
Open Admin → Workspace Settings → Integrations, select the provider, and follow its setup guide.
Why do I not see every integration in my workspace?
Available integrations depend on your account type, agreement, and enabled features. Agency, telephony, and BYOK options appear only when they are included in your setup.
Which telephony providers are supported?
Synthflow supports purchased numbers, Twilio, and SIP or PBX integrations across native and community-validated providers. See the telephony overview for options, tiers, and setup guides.
Can I use my own OpenAI or Azure credentials?
Yes, when BYOK is enabled for your workspace. Connect OpenAI or Azure under Admin → Workspace Settings → Integrations. See OpenAI BYOK and Azure for setup steps.
