Why Pydantic Powers the Vonage Python SDK
If you've ever passed a raw Python dict to an API and hoped for the best, Pydantic is the library that puts an end to that.
Karl from Vonage's tooling team joins Jeremy to talk about what it's like maintaining SDKs across six languages, and what he discovered when he started working on the Python SDK: Pydantic. They cover what Pydantic actually does, why validation errors as first-class citizens change how you think about data, and how the Vonage Python SDK uses it for request modeling, response parsing, and the model_dump pattern.
What you'll learn:
What Pydantic is and how it enforces types at runtime (not just statically)
How BaseModel, field validators, and model validators work
How the Vonage Python SDK uses Pydantic to validate API requests before they're sent
The model_dump(by_alias=True) pattern for snake_case ↔ camelCase mapping
Real-world conditional validation with @model_validator
