Introducing Writers
Bulk import user data by giving Vern an API spec

Vish Varma
Co-founder, CEO
Product

Point Vern at an OpenAPI spec, a docs URL, or just an API name, and it builds a writer for your destination automatically. No more hand-coding and maintaining an integration adapter per customer.
Each writer handles the hard parts out of the box:
Auth and credential management
Retries and rate limiting
Resumability on interrupted runs
Nested objects and foreign-key threading
Custom fields and provisioning
Vern maps your source entities to the right write endpoints and verifies each mapping against a real write before production.
You can now build and test API Writers from the Templates page here.
