Update Customers' Metadata in Bulk

Updates metadata parameters for a list of customers. Every resource in the list will receive the metadata defined in the request.

The request can include up to 10 MB of data.

The response returns a unique asynchronous action ID. Use this ID in the query paramater of the GET Async Action endpoint to check, e.g.:

• The status of your request (in queue, in progress, done, or failed)

• Resources that failed to be updated

• The report file with details about the update

If a product object is not found, it is upserted. This is shown in the report file in the GET Async Action endpoint. The upserted resources have value false in the found column and true in the updated column.

This API request starts a process that affects Voucherify data in bulk. In the case of small jobs (like bulk update), the request is put into a queue and processed when every other bulk request placed in the queue prior to this request is finished.
