Check Templates​

Every check is created from a check template. Set the check's template field to the template ID for your product, and set params.@type to the matching parameters type. The template decides which verification steps run, and the parameters type decides which subject data you must supply.

Create these checks with POST /v1/{parent}/checks. KYB Verification is in preview and is not yet available in v1, so create KYB checks with POST /v1alpha2/{parent}/checks and the v1alpha2 parameters type shown.

These are the templates documented for integrators, and each product guide documents its template's parameters and summary in full. ListCheckTemplates may also return other templates, such as right-to-rent and tenant referencing, which are enabled per organization and are not covered by these guides.

ListCheckTemplates returns template names in their fully qualified form, organizations/global/checkTemplates/{template}. CreateCheck requires the short form shown in the table, checkTemplates/{template}. Remove the organizations/global/ prefix before you pass a listed template to CreateCheck.

Your package determines which products your organization can use. Contact your account manager to add a product to your package.
