# Assemble product from FPO

POST https://api.runtype.com/v1/products/assemble
Content-Type: application/json

Assemble a product from a validated Full Product Object (FPO). API keys must carry PRODUCTS:WRITE (or PRODUCTS:CREATE) and SECRETS:WRITE, plus the write scope for every entity kind the FPO materializes (FLOWS:WRITE, AGENTS:WRITE, PRODUCTS:SURFACES:WRITE, SCHEDULES:WRITE, RECORDS:WRITE, EVALS:WRITE, SKILLS:WRITE), and SECRETS:READ when an inline HTTP step references a managed secret.
