The Synthflow API relies on API keys for every request. You can create and manage keys in Integrations → API Keys as long as your user role allows it.

Keep your key secret. Do not embed it in public repos, client-side code, or shared screenshots. Store it in an environment variable or a secrets manager and inject it at runtime.

All requests must include the key using HTTP Bearer authentication:

$curl https://api.synthflow.ai/v2/assistants \ 
>  -H "Authorization: Bearer $SYNTHFLOW_API_KEY"
Rotate keys periodically and delete any that are no longer in use to reduce exposure.

Generate an API key

  1. Sign in to your Synthflow workspace at synthflow.ai.
  2. Open Integrations → API Keys.
  3. Click Create new API key, copy the value, and store it securely.
  4. Use the key in your requests as shown above.
