• Accurate Pinterest refresh token lifetime: The Pinterest configuration docs previously stated refresh tokens are valid for 1 year. Pinterest has moved to a continuous refresh token model with a 60-day expiration that renews indefinitely on each refresh. The docs now describe this correctly, including how it behaves for apps created before and after September 25, 2025, and what happens if a refresh ever fails permanently.
• Corrected Pinterest supported image formats: The docs listed GIF as a supported Pin image format. It isn't. Pinterest supports BMP, JPEG, PNG, TIFF, and WEBP, and the docs now list TIFF in place of GIF to match Pinterest's actual requirements.
