How we connect

Read-only by default.
Your data never moves.

NumLK pulls metadata via standard OAuth — invoices, ledger entries, customer lists, deals. We don't store your raw payment data, employee PII, or sensitive contracts. Everything is encrypted in transit and at rest, audited under SOC 2 Type II.

  • OAuth 2.0 with read-only scopes wherever possible.
  • SOC 2 Type II audited; ISO 27001 in progress.
  • AES-256 encryption at rest, TLS 1.3 in transit.
  • Disconnect anytime — your data is purged within 30 days.

Don't see your tool?

Our integration team ships new connectors monthly based on customer requests. If you use it, we'll likely connect to it.

Common requests in flight:

  • Workday Adaptive Planning
  • Pleo, Spendesk
  • Sage 50, MYOB
