Connect a user's LMNT account once, then configure and run Create Custom Voice from your backend or agent.
import { PipedreamClient } from "@pipedream/sdk"
const pd = new PipedreamClient({
projectId: process.env.PIPEDREAM_PROJECT_ID!,
clientId: process.env.PIPEDREAM_CLIENT_ID!,
clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
projectEnvironment: "production",
})
const result = await pd.actions.run({
id: "lmnt-create-custom-voice",
externalUserId: "{external_user_id}", // any stable ID for this user in your system
configuredProps: {
lmnt: { authProvisionId: "apn_xxxxxxx" },
files: ["Audio Files Paths or URLs"],
name: "Name",
