title: Splunk Observability Cloud APM visibility filters API
version: 3.0.1
description: 'APIs to manage visibility filters on indexed and unindexed span tags in Splunk APM. These filters identify and hide span tag values that might contain sensitive data from everywhere in Splunk APM. Note that the tags are hidden rather than purged; information is not purged from Splunk APM until it expires after the 8-day default retention period.
Requirements
You must have an organization access token with the API permission or a session token to use the API.
You have to have the Splunk Observability Cloud admin, power, or read_only role to use the GET /apm/visibility/filter and GET /apm/visibility-filter/{FilterId} operations.
You have to have the Splunk Observability Cloud admin role to use the POST /apm/visibility-filter, DELETE /apm/visibility-filter/{FilterId}, and PUT /apm/visibility-filter/{FilterId}/enabled operations.'

note: Splunk's own OpenAPI objects, extracted from the React Server Component payload embedded in each of the 48 API reference pages at dev.splunk.com. The operations and schemas are Splunk's; the assembly into standalone documents is API Evangelist's. Splunk serves no fetchable spec file — dev.splunk.com answers 200 with an identical 6,638-byte shell for every asset path, including invented control paths — so this is NOT first-party publication and is not graded as such.

description: 'JSON object specifying the field values of a visibility filter in an API request.
Note the following logic involving the related matcher, visibleTags, and hiddenTags fields:
When all three fields are present, visibleTags defines the list of span tags that Splunk APM leaves visible in the span. Splunk APM hides any tags provided in the hiddenTags list, as well as any other not provided in either list.
When only matcher and visibleTags are present, visibleTags defines the list of span tags that Splunk APM leaves visible in the span. All other tags in each affected span are hidden.
When only matcher and hiddenTags are present, hiddenTags defines the list of span tags that Splunk APM hides in the span. All other tags in each affected span are left visible.
When only matcher is present and both visibleTags and hiddenTags are absent, the set of field names in matcher will define the list of visible tags. Splunk APM also leaves the following mandatory tags visible: sf_environment, sf_service, sf_endpoint, sf_operation, sf_httpMethod, sf_kind, sf_workflow, and sf_error.'
