`team_id`	string	Specify team_id starts with `T` in case of Org Token Example`T1234567890`
`to_old`	boolean	Specify `true` to convert `W` global user IDs to workspace-specific `U` IDs. Defaults to `false`. Default: Example`true`

Example responses

Common successful response

{
    "ok": true,
    "team_id": "T1KR7PE1W",
    "enterprise_id": "E1KQTNXE1",
    "user_id_map": {
        "U06UBSUN5": "W06M56XJM",
        "U06UEB62U": "W06PTT6GH",

    },
    "invalid_user_ids": [
        "U21ABZZXX"

Common error response

Typical error response when there are no mappings to provide

{
    "ok": false,
    "error": "not_enterprise_team"
}

Easily convert your vintage user IDs to Enterprise Grid-friendly global user IDs.

This method is best used in conjunction with turning off the translation layer for your app, as a bulk conversion step just after a workspace migrates to Enterprise Grid.

By providing a list of "local" user IDs associated with the same workspace as your token, you can exchange your IDs for "global" user IDs beginning with the letter W.

You can use any existing tokens authorized for the team to request for the user mappings.

The to_old parameter is false by default. When false, the method returns a user_id_map mapping from local user IDs to global user IDs. For a reverse mapping from global user IDs back to local user IDs, set to_old to true.

The method may only be used on workspaces that have migrated to enterprise. When used on typical workspaces, a not_enterprise_team error is thrown.

Additional nuance

Users that were already part of a workspace migrating to Enterprise Grid have two user IDs: a local user ID and a global user ID. Users that are created post-migration or on workspaces that are created after migration have only global user IDs.

When using this method and attempting to convert a global user ID to a local user ID and that corresponding user only has a global user ID, you'll receive the global user ID on both sides of the map.

Providing invalid users or user IDs not belonging to the related workspace will result with those IDs being listed in an invalid_user_ids array.

Errors

This table lists the expected errors that this method could return. However, other errors can be returned in the case where the service is down or other unexpected factors affect processing. Callers should always check the value of the ok params in the response.

Error	Description
`not_enterprise_team`	The workspace associated with the token is not part of an Enterprise organization. User IDs have not changed and there is nothing to map.
`too_many_users`	Too many user IDs provided in `users`. Up to 400 user IDs are allowed per request.
`not_authed`	No authentication token provided.
`invalid_auth`	Some aspect of authentication cannot be validated. Either the provided token is invalid or the request originates from an IP address disallowed from making the request.
`account_inactive`	Authentication token is for a deleted user or workspace when using a `bot` token.
`token_revoked`	Authentication token is for a deleted user or workspace or the app has been removed when using a `user` token.
`token_expired`	Authentication token has expired
`no_permission`	The workspace token used in this request does not have the permissions necessary to complete the request. Make sure your app is a member of the conversation it's attempting to post a message to.
`org_login_required`	The workspace is undergoing an enterprise migration and will not be available until migration is complete.
`ekm_access_denied`	Administrators have suspended the ability to post a message.
`missing_scope`	The token used is not granted the specific scope permissions required to complete this request.
`not_allowed_token_type`	The token type used in this request is not allowed.
`method_deprecated`	The method has been deprecated.
`deprecated_endpoint`	The endpoint has been deprecated.
`two_factor_setup_required`	Two factor setup is required.
`enterprise_is_restricted`	The method cannot be called from an Enterprise.
`team_access_not_granted`	The token used is not granted the specific workspace access required to complete this request.
`invalid_arguments`	The method was either called with invalid arguments or some detail about the arguments passed are invalid, which is more likely when using complex arguments like blocks or attachments.
`invalid_arg_name`	The method was passed an argument whose name falls outside the bounds of accepted or expected values. This includes very long names and names with non-alphanumeric characters other than `_`. If you get this error, it is typically an indication that you have made a very malformed API call.
`invalid_array_arg`	The method was passed an array as an argument. Please only input valid strings.
`invalid_charset`	The method was called via a `POST` request, but the `charset` specified in the `Content-Type` header was invalid. Valid charset names are: `utf-8` `iso-8859-1`.
`invalid_form_data`	The method was called via a `POST` request with `Content-Type` `application/x-www-form-urlencoded` or `multipart/form-data`, but the form data was either missing or syntactically invalid.
`invalid_post_type`	The method was called via a `POST` request, but the specified `Content-Type` was invalid. Valid types are: `application/json` `application/x-www-form-urlencoded` `multipart/form-data` `text/plain`.
`missing_post_type`	The method was called via a `POST` request and included a data payload, but the request did not include a `Content-Type` header.
`team_added_to_org`	The workspace associated with your request is currently undergoing migration to an Enterprise Organization. Web API and other platform operations will be intermittently unavailable until the transition is complete.
`invalid_json` [hidden]	The method was called via a `POST` request with `Content-Type` `application/json`, but the body was not valid JSON.
`json_not_object` [hidden]	The method was called via a `POST` request a valid JSON body, but the JSON value was not an object.
`ratelimited`	The request has been ratelimited. Refer to the `Retry-After` header for when to retry the request.
`accesslimited`	Access to this method is limited on the current network
`request_timeout`	The method was called via a `POST` request, but the `POST` data was either missing or truncated.
`upgrade_required` [hidden]	The calling application needs to be upgraded.
`service_unavailable`	The service is temporarily unavailable
`fatal_error`	The server could not complete your operation(s) without encountering a catastrophic error. It's possible some aspect of the operation succeeded before the error was raised.
`internal_error`	The server could not complete your operation(s) without encountering an error, likely due to a transient issue on our end. It's possible some aspect of the operation succeeded before the error was raised.

Warnings

This table lists the expected warnings that this method will return. However, other warnings can be returned in the case where the service is experiencing unexpected trouble.

Warning	Description
`missing_charset`	The method was called via a `POST` request, and recommended practice for the specified `Content-Type` is to include a `charset` parameter. However, no `charset` was present. Specifically, non-form-data content types (e.g. `text/plain`) are the ones for which `charset` is recommended.
`superfluous_charset`	The method was called via a `POST` request, and the specified `Content-Type` is not defined to understand the `charset` parameter. However, `charset` was in fact present. Specifically, form-data content types (e.g. `multipart/form-data`) are the ones for which `charset` is superfluous.
