Sandbox Environment

The sandbox environment returns schema-correct fake responses for every endpoint. Use it to verify your integration before connecting to production.

Base URL

https://sandbox.adzen.ai

What to expect

• Every POST /ugc/process call returns one fake ad named Sandbox Test Ad.
• The response shape is identical to production — same fields, same types.
• Impressions and disables accept the call and return a 200, but do nothing.
• No billing events are generated.

Interactive Swagger UI

The sandbox ships with a hosted Swagger UI at:

https://sandbox.adzen.ai/swagger-ui/?api-key=YOUR_SANDBOX_KEY

Paste your sandbox key in the URL and every "Try it out" request will include the header automatically. This is the fastest way to explore the API shape.

Testing failure paths

The sandbox returns successful responses by default. If you need to test how your client handles errors, send a deliberately malformed request — the API will return the same 400 validation errors as production.
