Use the Count API to estimate Vault API export sizes

Quick launch summary 

We’re adding a Count API to the Vault API. The Count API enables you to see the number of messages, files, or other data items that match a search query. 

You can use the number of items to estimate the size of the export, and then choose to proceed with the export or adjust the query to retrieve fewer items. This can help ensure a successful export by reducing the likelihood of export errors due to size. 

Getting started 

  • Admins: Visit the API documentation to learn more about the Count API and review an example. 
  • End users: No end user impact. 

Rollout pace 


  • Available to Business Plus, Enterprise Standard, Enterprise Plus, Enterprise for Education, as well as other customers with the Vault add-on license
