/sys/sync

The /sys/sync endpoints are used to configure destinations and associate secrets to sync with these destinations.

Each destination type has its own endpoint for creation & update operations, but share the same endpoints for read & delete operations.

Configuration

The sys/sync/config endpoint is used to set configuration parameters for the sync system as a whole.

Restricted endpoint

The API path can only be called from the root or administrative namespace.

Method	Path
`PATCH`	`sys/sync/config`

Parameters

disabled (bool: false) - Disables sync operations from sending secrets in Vault to external destinations when set to true. While disabled, actions performed in Vault which trigger a sync operation will instead get queued to be processed once syncing is reactivated. Queued operations will have a status of PENDING until they are completed. This is provided as a safety mechanism for emergencies.
queue_capacity (int: 1,000,000) - Maximum number of pending sync operations allowed on the internal queue.

Sample payload

{
    "disabled": "true",
    "queue_capacity": 1000000

Read associations

This endpoint returns all existing associations for a given destination. An association references the mount via its accessor. Associations also contain the latest sync status for the secret they represent.

Note

In the event a synchronization operation does not succeed, the sync status will indicate the cause of the error and is a useful tool when troubleshooting.

Method	Path
`GET`	`/sys/sync/destinations/:type/:name/associations`

Parameters

type (string: <required>) - Specifies the destination type. This is specified as part of the URL.
name (string: <required>) - Specifies the name for this destination. This is specified as part of the URL.

Sample request

$ curl \
    --header "X-Vault-Token: ..." \
    --request GET \
    http://127.0.0.1:8200/v1/sys/sync/destinations/aws-sm/my-store-1/associations

Sample response

{
    "request_id": "uuid",
    "lease_id": "",
    "renewable": false,
    "lease_duration": 0,
    "data": {
        "associated_secrets": {
            "kv_eb4acbae/my-secret-1": {

        "store_type": "aws-sm"
    },
    "wrap_info": null,
    "warnings": null,
    "auth": null
}

Set association

The set endpoint links a secret to an existing destination using the secret name and mount path and triggers a sync operation. If the secret is already associated with the destination, Vault performs a refresh without recreating the link. Triggering a refresh is useful to push the secret to external systems or retry a failed sync operation if the underlying problem that caused the failure has been resolved.

Note

Only KV-v2 secrets are supported at the moment.

Method	Path
`POST`	`/sys/sync/destinations/:type/:name/associations/set`

Parameters

type (string: <required>) - Specifies the destination type. This is specified as part of the URL.
name (string: <required>) - Specifies the name for this destination. This is specified as part of the URL.
mount (string: <required>) - Specifies the mount where the secret is located. For example, if you can read a secret with vault kv get -mount=my-kv my-secret-1, the mount name is my-kv.
secret_name (string: <required>) - Specifies the name of the secret to synchronize. For example, if you can read a secret with vault kv get -mount=my-kv my-secret-1, the secret name is my-secret-1.

Sample payload

{
    "mount": "my-kv",
    "secret_name": "my-secret-1"
}

Sample request

$ curl \
    --header "X-Vault-Token: ..." \
    --request POST \

    "wrap_info": null,
    "warnings": null,
    "auth": null
}

Remove association

The remove endpoint unlinks a secret from an existing destination based on the secret name and mount path, and triggers an unsync operation. Unsync operations delete the secret from the external system. The unsync operation reports success if the targeted association is removed, does not exist, or the secret was already removed from the external system.

Method	Path

Parameters

type (string: <required>) - Specifies the destination type. This is specified as part of the URL.
name (string: <required>) - Specifies the name for this destination. This is specified as part of the URL.
mount (string: <required>) - Specifies the mount where the secret is located. For example, if you can read a secret with vault kv get -mount=my-kv my-secret-1, the mount name is my-kv.
secret_name (string: <required>) - Specifies the name of the secret to synchronize. For example, if you can read a secret with vault kv get -mount=my-kv my-secret-1, the secret name is my-secret-1.

Configure a custom GitHub app

Use the POST operation with sys/sync/github-apps endpoint to configure a custom GitHub application for syncing secrets with GitHub repositories.

Method	Path
`POST`	`sys/sync/github-apps/:name`

Parameters

name (string: <required>) - Specifies a custom name for the GitHub application that is used when configuring the destination. Although this can be any name, we recommend using the same app name configured in GitHub.
app_id (string: <required>) - Specifies the GitHub application ID, provided by GitHub.
private_key (string: <required>) - Specifies the private key used to authenticate with the GitHub application.

Sample payload

{
    "app_id": "true",
    "private_key":  "<PRIVATE KEY PEM>"
}

Sample requests

$ curl \
    --header "X-Vault-Token: ..." \
    --request POST \
    --data @payload.json
    http://127.0.0.1:8200/v1/sys/sync/github-apps/my-custom-app

Sample response

{
    "request_id": "uuid",
    "data": {
        "app_id": 123456,
        "fingerprint": "<fingerprint>",
        "name": "my-custom-app",
        "private_key": "*****"
    },
    "mount_type": "system"
}

Read custom GitHub app

Use the GET operation with sys/sync/github-apps to view details about the configured GitHub application.

Method	Path
`GET`	`sys/sync/github-apps/:name`

Parameters

name (string: <required>) - Specifies a custom name for the GitHub application.

Sample requests

$ curl \
    --header "X-Vault-Token: ..." \
    --request GET \
    http://127.0.0.1:8200/v1/sys/sync/github-apps/my-custom-app

Sample response

{
    "request_id": "uuid",
    "data": {
        "app_id": 123456,
        "fingerprint": "<fingerprint>",
        "name": "my-custom-app",
        "private_key": "*****"
    },
    "mount_type": "system"
}

Delete custom GitHub app

Use the DELETE operation with sys/sync/github-apps to delete a configured GitHub application.

You cannot delete applications with active authentication destination references. Deleting an application configuration does not delete the GitHub application from GitHub.

Method	Path
`DELETE`	`sys/sync/github-apps/:name`

Parameters

name (string: <required>) - Specifies a custom name for the GitHub application.

Sample requests

$ curl \
    --header "X-Vault-Token: ..." \
    --request DELETE \
    http://127.0.0.1:8200/v1/sys/sync/github-apps/my-custom-app
