Only the fields you send are touched; omitted fields are left as they were. A field set to the mask sentinel (`••••••`) is SKIPPED — echoing a masked secret back keeps the stored one, so you never overwrite a credential you were never shown; send a real value only to change it. This operation STORES CREDENTIALS and can wire a LIVE external integration (it is the domain's lowest agent tier): do not call it speculatively, and confirm the credentials with the operator first. 404 on an unknown key, 400 on a malformed config (a nested/non-primitive value). Requires `pos.settings.manage`. ## OpenAPI ````yaml /openapi.json put /v1/integrations/{key} openapi: 3.0.3 info: title: Solya POS API version: 1.0.0 description: >- The Solya POS backend HTTP surface.
