-- `Secret.Tags` - A map of key-value user-defined metadata associated with the source secret
+  matches to the first mapping that applies. Once Vault imports a secret with a
+  particular mapping, subsequent reads from the same source will ignore that
+  secret. See the [priority section](/vault/docs/import/mappings#priority) for an example.
 
-You can also apply simple binary conditions to input values:
+</Tip>
-
-- `Secret.Name != "foo"`
-- `Secret.Tags.Team matches "my-dept.*"`
-- `Secret.Tags contains "my-required-tag-name"`
-
-These can be combined using `and`, `or`, and `not`:
-
-- `(Secret.Name == "foo" or Secret.Tags.Team == "my-team") and Secret.Tags.Category = "my-cat"`
-
-#### Transformers
-
-Transform stanzas come in two forms: `exact` and `regexp`.
-
-An exact transform allows renaming a secret during import, so that the `from` secret name
-is imported into Vault as a secret named `to`.  In the following example it, takes a source secret
-named `foo` and transforms it to `foosball` during import.
-
-```hcl
-  transform "exact" {
-    from = "foo"
-    to = "foosball"
-  }
-```
-
-`regexp` transforms rename secrets during import using
-[Go regular expression syntax](https://github.com/google/re2/wiki/Syntax). For
-example, the transform below imports any secret in the source whose name starts
-with `foo` and replaces the `foo` prefix with `bar`.
-
-```hcl
-  transform "regexp" {
-    from = "foo(.*)"
-    to = "bar$1"
-  }
-  transform "regexp" {
-    from = "foo(?P<suffix>.*)"
-    to = "bar$suffix"
-  }
-```
-
-The `from` value supports parentheses to bookend capture groups and named
-capture groups using the syntax `(?P<name>re)`. When you use named capture
-groups, you can reference the named group in the `to` value. For example,
-`$name` instead of `$1`.

+page_title: Secrets import mappings
+description: Mappings lets users apply various filtering methods to secrets being imported in to Vault.
+---
+
+# Secrets import mappings
+
+Vault supports multiple filter types for mapping blocks. Each of the types provides a different mechanism
+used to filter the scanned secrets and determine which will be imported in to Vault.
+
+
+## Argument reference
+
+Refer to the [HCL syntax](/vault/docs/import#hcl-syntax-2) for arguments common to all mapping types.
+
+## Passthrough mapping filters
+
+The passthrough mapping block `mapping_passthrough` allows all secrets through from the specified source to the
+specified destination. For example, one use case is setting it as a base-case for imported secrets. By assigning
+it the lowest priority in the import plan, all other mapping blocks will be applied first. Secrets that fail
+to match any of the previous mappings will fall through to the passthrough block and be collected in a single
+KVv2 location.
+
+### Additional arguments
+
+There are no extra arguments to specify in a `mapping_passthrough` block.
+
+### Example
+
+In this example, every single secret that `my-gcp-source-1` scans from GCP Secret Manager will be imported
+to the KVv2 secrets engine mount defined in `my-dest-1`.
+
+```hcl
+mapping_passthrough {
+  name        = "my-map-1"
+  source      = "my-gcp-source-1"
+  destination = "my-dest-1"
+  priority    = 1
+}
+```
+
+## Metadata
+
+The metadata mapping block `mapping_metadata` allows secrets through from the specified source to the specified
+destination if they contain matching metadata key-value pairs. Metadata is not supported in all external secret
+management systems, and ones that do may use different terminology for metadata. For example, AWS allows tags
+on secrets while [GCP](/vault/docs/import/gcpsm) allows labels.
+
+### Additional arguments
+
+* `tags` `(string: <required>)` - A set of key-value pairs to match on secrets from the external system. All of the specified
+keys must be found on a secret and all of the values must be exact matches. Specifying a key in this mapping with
+an empty value, i.e. `""`, acts as a wildcard match to the external system's key's value.
+
+### Example
+
+In this example, `my-map-1` will only import the secrets into the destination `my-dest-1` that contain a tag with
+a key named `importable` and its value set to `true`. 
+
+```hcl
+mapping_metadata {
+  name        = "my-map-1"
+  source      = "my-gcp-source-1"
+  destination = "my-dest-1"
+  priority    = 1
+
+  tags = {
+    "importable" = "true"
+  }
+}
+```
+
+## Regex
+
+The regex mapping block `mapping_regex` allows secrets through from the specified source to the specified
+destination if their secret name passes a regular expression check.
+
+### Additional arguments
+
+* `expression` `(string: <required>)` - The regular expression used to match secrets' names from the external system.
+
+### Example
+
+In this example, any secret in the GCP source whose name begins with `database/` will be imported into Vault.
+
+```hcl
+mapping_regex {
+  name        = "my-map-1"
+  source      = "my-gcp-source-1"
+  destination = "my-dest-1"
+  priority    = 1
+  expression  = "^database/.*$"
+}
+```
+
+## Priority
+
+Priority works in a "first match" fashion where lower values are higher priority. To explain in more detail,
+consider the above metadata example with a second additional mapping.
+
+Below are two metadata mappings. The first, `my-map-1`, has a priority of 1. This will only import the secrets
+into the destination `my-dest-1` that contain both tag keys `database` and `importable`. Each of these keys' values
+must also match to `users` and `true` respectively. The second, `my-map-2`, has a priority of 2. Even though all
+the secrets in the first mapping would also qualify for the second mapping's filtering rule, those secrets will only
+be imported into `my-dest-1` because of `my-map-2`'s lower priority. All remaining secrets that have the tag
+`importable` with a value of `true` will be imported into `my-dest-2`. 
+
+```hcl
+mapping_metadata {
+  name        = "my-map-1"
+  source      = "my-gcp-source-1"
+  destination = "my-dest-1"
+  priority    = 1
+
+  tags = {
+    "database"   = "users"
+    "importable" = "true"
+  }
+}
+
+mapping_metadata {
+  name        = "my-map-2"
+  source      = "my-gcp-source-1"
+  destination = "my-dest-2"
+  priority    = 2
+
+  tags = {
+    "importable" = "true"
+  }
+}
+```
