A thread event will only be created in the thread ID provided. If you want an event to appear in all threads for a customer please use a customer event.
To create a thread event you need a thread ID. You can get this by creating a thread 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 thread 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:
  • threadEvent:create
  • threadEvent:read
  • thread:read
  • customer:read
import { PlainClient, uiComponent } from '@team-plain/typescript-sdk';

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

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

  threadId: 'th_01HB924RWAW8H3Q8KZDFWYBJHZ',

  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: 'ex-id-1',
});

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