Policy, approvals and errors

SDK function policy ID: hubspot.schemas_get_schemas. Catalog operation: schemas_get_schemas. Rules can name either ID; function rules distinguish managed calls and conservatively cover raw calls sharing the route. Existing grant permissions and policy rules apply. wait() returns an immediate result or waits for a required approval; it never approves the request itself. Persist the approval ID to resume after a restart.

Provider errors retain their response; JSON decoding raises ProviderAPIError for provider failures. ManagedOperationError identifies contract/input/retention errors. See error handling and provider-specific behavior. Sensitive input may be refused before approval storage. A decoding error never resubmits a write.

Required provider scopes: ["crm.objects.custom.highly_sensitive.read.v2", "crm.objects.custom.read", "crm.objects.custom.sensitive.read.v2", "crm.schemas.custom.read"]
