ACL Token HTTP API

The /acl/token endpoints create, read, update, list, clone and delete ACL tokens in Consul.

For more information on how to setup ACLs, refer to the following resources:

• Access control list (ACL) overview
• ACL tutorial

Create a Token

This endpoint creates a new ACL token.

The table below shows this endpoint's support for blocking queries, consistency modes, agent caching, and required ACLs.

The corresponding CLI command is consul acl token create.

Query Parameters

• ns (string: "") EnterpriseEnterprise - Specifies the namespace of the token you create. You can also specify the namespace through other methods.

JSON Request Body Schema

• AccessorID (string: "") - Specifies a UUID to use as the token's Accessor ID. If not specified a UUID will be generated for this field. Added in v1.5.0.

• SecretID (string: "") - Specifies a UUID to use as the token's Secret ID. If not specified a UUID will be generated for this field. Added in v1.5.0. Note: The SecretID is used to authorize operations against Consul and should be generated from an appropriate cryptographic source.

• Description (string: "") - Free form human readable description of the token.

• Policies (array<PolicyLink>) - The list of policies that should be applied to the token. A PolicyLink is an object with an "ID" and/or "Name" field to specify a policy. With the PolicyLink, tokens can be linked to policies either by the policy name or by the policy ID. When policies are linked by name they will be internally resolved to the policy ID. With linking tokens internally by IDs, Consul enables policy renaming without breaking tokens.

• Roles (array<RoleLink>) - The list of roles that should be applied to the token. A RoleLink is an object with an "ID" and/or "Name" field to specify a role. With the RoleLink, tokens can be linked to roles either by the role name or by the role ID. When roles are linked by name they will be internally resolved to the role ID. With linking tokens internally by IDs, Consul enables role renaming without breaking tokens. Added in Consul 1.5.0.

• TemplatedPolicies (list of maps) - The list of templated policies that should be applied to the role.

  • TemplateName (string: <required>) - The templated policy name.
  • TemplateVariables (map of strings|maps: <optional>) - The templated policy variables. Not all templated policies require variables.

• ServiceIdentities (array<ServiceIdentity>) - The list of service identities that should be applied to the token. Added in Consul 1.5.0.

  • ServiceName (string: <required>) - The name of the service. The name must be no longer than 256 characters, must start and end with a lowercase alphanumeric character, and can only contain lowercase alphanumeric characters as well as - and _.

  • Datacenters (array<string>) - Specifies the datacenters the effective policy is valid within. When no datacenters are provided the effective policy is valid in all datacenters including those which do not yet exist but may in the future.

• NodeIdentities (array<NodeIdentity>) - The list of node identities that should be applied to the token. Added in Consul 1.8.1.

  • NodeName (string: <required>) - The name of the node. The name must be no longer than 256 characters, must start and end with a lowercase alphanumeric character, and can only contain lowercase alphanumeric characters as well as - and _.

  • Datacenter (string: <required>) - Specifies the nodes datacenter. This will result in effective policy only being valid in that datacenter.

• Local (bool: false) - If true, indicates that the token should not be replicated globally and instead be local to the current datacenter.

• ExpirationTime (time: "")- If set this represents the point after which a token should be considered revoked and is eligible for destruction. The default unset value represents NO expiration. This value must be between 1 minute and 24 hours in the future. Added in Consul 1.5.0.

• ExpirationTTL (duration: 0s) - This is a convenience field and if set will initialize the ExpirationTime field to a value of CreateTime + ExpirationTTL. This field is not persisted beyond its initial use. Can be specified in the form of "60s" or "5m" (i.e., 60 seconds or 5 minutes, respectively). This value must be no smaller than 1 minute and no longer than 24 hours. Added in Consul 1.5.0.

• Namespace (string: "") EnterpriseEnterprise - Specifies the namespace of the token you create. This field takes precedence over the ns query parameter, one of several other methods to specify the namespace.

JSON Request Body Schema

• AccessorID (string: "") - Specifies the accessor ID of the token being updated. This field is required in the URL path but may also be specified in the JSON body. If specified in both places then they must be an exact match. This field is immutable. If not present in the body and only in the URL then it will be filled in by Consul.

• SecretID (string: "") - Specifies the secret ID of the token being updated. This field is immutable so if present in the body then it must match the existing value. If not present then the value will be filled in by Consul.

• Description (string: "") - Free form human readable description of this token.

With linking tokens internally by IDs, Consul enables policy renaming without breaking tokens.

• Roles (array<RoleLink>) - The list of roles that should be applied to the token. A RoleLink is an object with an "ID" and/or "Name" field to specify a role. With the RoleLink, tokens can be linked to roles either by the role name or by the role ID. When roles are linked by name they will be internally resolved to the role ID.

  • ServiceName (string: <required>) - The name of the service. The name must be no longer than 256 characters, must start and end with a lowercase alphanumeric character, and can only contain lowercase alphanumeric characters as well as - and _.

  • Datacenters (array<string>) - Specifies the datacenters the effective policy is valid within. When no datacenters are provided the effective policy is valid in all datacenters including those which do not yet exist but may in the future.

• NodeIdentities (array<NodeIdentity>) - The list of node identities that should be applied to the token. Added in Consul 1.8.1.

  • NodeName (string: <required>) - The name of the node. The name must be no longer than 256 characters, must start and end with a lowercase alphanumeric character, and can only contain lowercase alphanumeric characters as well as - and _.

  • Datacenter (string: <required>) - Specifies the nodes datacenter. This will result in effective policy only being valid in that datacenter.

• Local (bool: false) - If true, indicates that this token should not be replicated globally and instead be local to the current datacenter. This value must match the existing value or the request will return an error.

• AuthMethod (string: "") - Specifies the name of the auth method that created this token. This field is immutable so if present in the body then it must match the existing value. If not present then the value will be filled in by Consul.

• ExpirationTime (time: "") - Specifies the expiration time for the token being updated. This field is immutable so if present in the body then it must match the existing value. If not present then the value will be filled in by Consul.

• Namespace (string: "") EnterpriseEnterprise - Specifies the namespace of the token you update. This field takes precedence over the ns query parameter, one of several other methods to specify the namespace.
