Asked before implementation
Who implements the integration?
Your technical team or your system implementer — this guide plus the technical reference cover everything needed; typical effort is one working day.
Does the external system write into TAC Flow?
No — the partner API is read-only in its current version, which makes the integration inherently safe: no external mistake can corrupt your data.
