API Reference

PUT multiple Custom Field Values Async

This endpoint is used to asynchronously insert and update Custom Field Values. Use this endpoint for improved performance. Maximum of 10,000 objects per request.

🚧

Limit for object set fields

You can add a maximum of 256 objects to an object set or multi-select picker custom field with this API.

🚧

Value size limit

This endpoint may not accept a custom field value that's more than 190 KB in size. This is a known issue that will be addressed.

For Alation Cloud Service customers on the cloud-native architecture, this API runs two background jobs when updating custom field values. The API response returns the ID of the first job. Use that ID to query the Jobs API. The response from the Jobs API returns the ID of the second job.

If either job fails, you must retry the API request.

As background for why we run two jobs, Alation is transitioning from storing custom field values in one data store to another, faster data store. To keep data consistent and performant during the transition, we write asynchronously to both places. Eventually the second one will be removed.
