You can add multiple labels to a thread with a call to addLabels. Label type IDs passed to this endpoint should not be archived, we return a validation error with code cannot_add_label_using_archived_label_type for any which are submitted. If a label type you provide is already added to the thread we will return a validation error with code label_with_given_type_already_added_to_thread. You can retrieve label type IDs in the Plain UI settings by hovering over a label type and selecting ‘Copy label ID’ from the overflow menu. This operation requires the following permissions:
  • label:create
  • Typescript SDK
  • GraphQL
import { PlainClient } from '@team-plain/typescript-sdk';

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

const res = await client.addLabels({
  labelTypeIds: ['lt_01HB8BTNVM7GEBKBEDNC2K8ST7'],
  threadId: 'th_01HD1G6649R1DK061W27VBT7QB',
});

if (res.error) {
  console.error(res.error);
} else {
  console.log(res.data);
}
This will output:
