OpenRTB downloads: cheat sheet, sample payloads, and test collections
Reference material and test data you can keep offline. Everything is free to use; the sample payloads are synthetic.
OpenRTB 2.6 cheat sheet
Request, impression, and response fields with types and defaults, key enums, macros, and no-bid codes. Printable, also as a PDF.
Open →Sample payloads
Valid and deliberately broken bid requests, responses, and ARTF envelopes, with a README naming what each broken one trips.
Download →Postman collection
The bid request samples as POSTs to a bidder_url variable, valid and broken, with the OpenRTB version header set.
Download →Bruno collection
The same requests as a Bruno collection with a local environment.
Download →JSON Schemas
Draft 2020-12 schemas for bid requests and responses in every supported OpenRTB version.
Open →Use them in a test loop
Send the collection at a local bidder, then validate what it returns against the request with the rtblint CLI. The validation in CI guide shows how to fail a build on spec violations.
