Client API (removed)
The client sub-account feature and its thirteen Client.* API commands were removed in v5.9.1 (issue #1875). There is no replacement: the feature was discontinued, not renamed.
The following commands are no longer registered. Calling any of them returns the invalid-command envelope shown below, with HTTP status 400:
Client.Create, Client.Update, Clients.Get, Clients.Delete, Client.Login, Client.PasswordRemind, Client.PasswordReset, Client.AssignCampaigns, Client.AssignSubscriberLists, Client.Lists.Get, Client.List.Get, Client.Campaigns.Get, Client.Campaign.Get
{
"Success": false,
"ErrorCode": 100003,
"ErrorText": "Invalid API command: \"clients.get\" not found. Please check your command name or use versioned endpoints: /api/v1/ or /api/legacy/.",
"Errors": [
{
"Code": 100003,
"Message": "Invalid API command: \"clients.get\" not found. Please check your command name or use versioned endpoints: /api/v1/ or /api/legacy/."
}
]
}If an integration still calls these commands, remove the calls. Data that used to be scoped to a client (assigned lists and campaigns) belongs to the owning user account and is reachable through the user-scoped commands in Lists and Campaigns.
This page is kept so that old links resolve. It will be dropped from the sidebar in a later version.
