A customer event will be created in all threads that belong to the provided customer ID. If you want an event to appear in a specific thread use a thread event.
To create an event you need a customer ID. You can get this by upserting a customer in Plain, from data in webhooks or other API calls you made. If you want to test this, press ⌘ + K on any thread and then “Copy customer ID” to get an ID you can experiment with. In this example we’ll be creating the following event:
Example event
For this you’ll need an API key with the following permissions:
  • customerEvent:create
import { PlainClient, uiComponent } from '@team-plain/typescript-sdk';

const client = new PlainClient({ apiKey: 'plainApiKey_xxx' });

const res = await client.createCustomerEvent({
  title: 'API key generated',

  customerIdentifier: {
    // You can use the email:
    emailAddress: 'jane@acme.com',

    // ...or if you set external id on customers:
    // externalId: 'YOUR_ID',

    // ...or you can use the customer's id in Plain:
    // customerId: 'c_01H14DFQ4PDYBH398J1E99TWSS'
  },

  components: [
    uiComponent.text({
      text: 'New API key was added with the fingerprint **3b7896975ee9fd15eeb7** with 4 associated roles.',
    }),
    uiComponent.spacer({
      size: 'M',
    }),
    uiComponent.linkButton({
      label: 'View in admin',
      url: 'https://admin.your-app.com',
    }),
  ],

  // Optional - if provided, this will ensure that this event can only
  // be created once and fail on the second time. This external id acts
  // as an idempotency key while also letting you correlate an event to
  // something your systems.
  externalId: 'XXX',
});

if (res.error) {
  console.error(res.error);
} else {
  console.log(res.data);
}
Which would console.log:
