outboundsync.com
OutboundSync is an outbound data integration and orchestration platform that syncs activity from outbound tools into CRMs like HubSpot, Salesforce, Close, and Attio. It helps teams route replies, automate workflows, attribute revenue, and maintain block or exclusion lists from CRM data.
OutboundSync exposes one documented developer surface: a Bearer-authenticated REST API at `https://app.outboundsync.com/api/v1` for validating API keys and listing accessible CRM connections; no public GraphQL API, MCP server, or CLI is currently documented on outboundsync.com.
- OutboundSync API v1discovered
Log in to OutboundSync, then go to Connected Accounts → API keys. Create a key, choose either All connections (account-wide) or a single connection scope, and copy the plaintext key immediately; it is only shown once. An administrator must enable API access for at least one CRM connection before the key can successfully call the API. Store the key in a secret manager or an environment variable such as OUTBOUNDSYNC_API_KEY.
